Is typeof in C, really an operator? I'm thinking because there is no polymorphism in C, that there is nothing to do at run-time. That is, the answer to typeof is known at compile-time. (I can't think of a use of typeof that would not be known at compile time.) So it appears to be more of a compile-time directive, than an operator. Does typeof use any (processor) run-time (in GCC)? Since typeof is a compiler extension, there is not really a definition for it, but in the tradition of C it would be an operator, e.g sizeof and _Alignof are also seen as an operators. And you are mistaken, C has dynamic types that are only determined at run time: variable modified (VM) types. size_t n = strtoull(argv[1], 0, 0); double A[n][n]; typeof(A) B; can only be determined at run time. Add on in 2021: there are good chances that typeof with similar rules as for sizeof will make it into C23. @JensGustedt I' want to ask you if I can i call this a "dynamic type" the same way we call types in other languages like python as this is just plain old VLA which has known type of double with just missing boundaries sizes. Anyway, VLA's are not recommended as they generate lots of code and they are slow. ex: Linux removed all it;s It's a GNU extension. In a nutshell it's a convenient way to declare an object having the same type as another. For example: int x; /* Plain old int variable. */ typeof(x) y; /* Same type as x. Plain old int variable. */ It works entirely at compile-time and it's primarily u...

In this article The logical Boolean operators perform logical operations with !), binary logical AND ( &), OR ( |), and exclusive OR ( ^), and the binary conditional logical AND ( &&) and OR ( ||). • Unary ! (logical negation) operator. • Binary & (logical AND), | (logical OR), and ^ (logical exclusive OR) operators. Those operators always evaluate both operands. • Binary && (conditional logical AND) and || (conditional logical OR) operators. Those operators evaluate the right-hand operand only if it's necessary. For operands of the &, |, and ^ operators perform bitwise logical operations. For more information, see Logical negation operator ! The unary prefix ! operator computes logical negation of its operand. That is, it produces true, if the operand evaluates to false, and false, if the operand evaluates to true: bool passed = false; Console.WriteLine(!passed); // output: True Console.WriteLine(!true); // output: False The unary postfix ! operator is the Logical AND operator & The & operator computes the logical AND of its operands. The result of x & y is true if both x and y evaluate to true. Otherwise, the result is false. The & operator evaluates both operands even if the left-hand operand evaluates to false, so that the operation result is false regardless of the value of the right-hand operand. In the following example, the right-hand operand of the & operator is a method call, which is performed regardless of the value of the left-hand operand: bool SecondOperand(...

What are Operators in C? The C programming language utilizes operators as symbols representing precise operations to be executed on one or more operands. C provides a wide range of operators that can perform arithmetic, logical, and bitwise operations and operations on pointers and arrays. Operators are symbols that help in performing functions of mathematical and logical nature. The classification of C operators is as follows: • Arithmetic • Relational • Logical • Bitwise • Assignment • Conditional • Special Even though there are many operators, the execution of these operations happens based on the precedence given to them. Precedence is the order in which the compiler executes the code comprising numerous operators. Web development, programming languages, Software testing & others Explanation of Operators in C Below is a detailed explanation of operators in C: #1 Arithmetic Operators These operators are responsible for performing arithmetic or mathematical operations like addition (+), subtraction (-), multiplication (*), division (/), the remainder of the division (%), increment (++), and decrement (–). There are two types of arithmetic operators: • Unary Operators: This type of operator works with a single value (operand) like ++ and –. • Binary Operators: This type of operator works with two operands like +,-,*,/ Here is a tabular form of the number of Operator Function + Adds two values – Subtract a second value from the first. * Multiply two values / Divide numerat...

In C programming, data types are declarations for variables. This determines the type and size of data associated with variables. For example, int myVar; Here, myVar is a variable of int (integer) type. The size of int is 4 bytes. Basic types Here's a table containing commonly used types in C programming for quick access. Type Size (bytes) Format Specifier int at least 2, usually 4 %d, %i char 1 %c float 4 %f double 8 %lf short int 2 usually %hd unsigned int at least 2, usually 4 %u long int at least 4, usually 8 %ld, %li long long int at least 8 %lld, %lli unsigned long int at least 4 %lu unsigned long long int at least 8 %llu signed char 1 %c unsigned char 1 %c long double at least 10, usually 12 or 16 %Lf int Integers are whole numbers that can have both zero, positive and negative values but no decimal values. For example, 0, -5, 10 We can use int for declaring an integer variable. int id; Here, id is a variable of type integer. You can declare multiple variables at once in C programming. For example, int id, age; The size of int is usually 4 bytes (32 bits). And, it can take 2 32 distinct states from -2147483648 to 2147483647. float and double float and double are used to hold real numbers. float salary; double price; In C, floating-point numbers can also be represented in exponential. For example, float normalizationFactor = 22.442e2; What's the difference between float and double? The size of float (single precision float data type) is 4 bytes. And the size of doubl...

Output i d d In this example, we have included the “typeinfo” library so that we can use typeid() function to check the data type. We have defined an integer variable ‘num’ and converted it into a double using static_cast. After that, we print the data types of variables and pass static_cast(num) in typeid() function to check its data type. we can see the output “i, d, d” is printed where ‘i’ denotes integer and ‘d’ denotes double. 2. dynamic_castdivBlock The Output Dog barks. Failed to cast to Cat. Explanation: The first line of output is printed because the ‘animalPtr’of the ‘Animal’type is successfully cast to the ‘Dog’ type and speak() function of the Dog class is invoked but the casting of the ‘Animal’ type to ‘Cat’ type is failed because ‘animalPtr’ points to a ‘Dog’ object thus, the dynamic cast fails because the typecasting is not safe. 3. const_cast The const_cast operator is used to modify the const or volatile qualifier of a variable. It allows programmers to temporarily remove the constancy of an object and make modifications. Caution must be exercised when using const_cast, as modifying a const object can lead to undefined behavior. Syntax for const_cast const_cast (expression); Example of const_cast Output Integer Address: 0x7fff64789f1c Char Address: 0x7fff64789f1c In the above example, we have defined an int variable ‘number’ and then store the address of ‘number’ in ‘numberPointer’of the int type after that we have converted the ‘numberPointer’ of the int...

Assume variable A holds 1 and variable B holds 0, then − Operator Description Example && Called Logical AND operator. If both the operands are non-zero, then the condition becomes true. (A && B) is false. || Called Logical OR Operator. If any of the two operands is non-zero, then the condition becomes true. (A || B) is true. ! Called Logical NOT Operator. It is used to reverse the logical state of its operand. If a condition is true, then Logical NOT operator will make it false. !(A && B) is true. Example Try the following example to understand all the logical operators available in C − Live Demo #include main() When you compile and execute the above program, it produces the following result − Line 1 - Condition is true Line 2 - Condition is true Line 3 ...

C Operators are symbols that represent operations to be performed on one or more operands. C provides a wide range of operators, which can be classified into different categories based on their functionality. Operators are used for performing operations on variables and values. What are Operators in C? Operators can be defined as the symbols that help us to perform specific mathematical, relational, bitwise, conditional, or logical computations on operands. In other words, we can say that an operator operates the operands. For example, ‘+’ is an operator used for addition, as shown below: c = a + b; Here, ‘+’ is the operator known as the addition operator, and ‘a’ and ‘b’ are operands. The addition operator tells the compiler to add both of the operands ‘a’ and ‘b’. The functionality of the C programming language is incomplete without the use of operators. Types of Operators in C C has many built-in operators and can be classified into 6 types: Operators in C The above operators have been discussed in detail: 1. Arithmetic Operations in C These operators are used to perform arithmetic/mathematical operations on operands. Examples: (+, -, *, /, %,++,–). Arithmetic operators are of two types: a) Unary Operators: Operators that operate or work with a single operand are unary operators. For example: Increment(++) and Decrement(–) Operators int val = 5; cout= , <= )(See int a = 3; int b = 5; cout<<(a < b); // operator to check if a is smaller than b 3. Logical Operator in C Log...

When shifting left, there is no difference between arithmetic and logical shift. When shifting right, the type of shift depends on the type of the value being shifted. (As background for those readers unfamiliar with the difference, a "logical" right shift by 1 bit shifts all the bits to the right and fills in the leftmost bit with a 0. An "arithmetic" shift leaves the original value in the leftmost bit. The difference becomes important when dealing with negative numbers.) When shifting an unsigned value, the >> operator in C is a logical shift. When shifting a signed value, the >> operator is an arithmetic shift. For example, assuming a 32 bit machine: signed int x1 = 5; assert((x1 >> 1) == 2); signed int x2 = -5; assert((x2 >> 1) == -3); unsigned int x3 = (unsigned int)-5; assert((x3 >> 1) == 0x7FFFFFFD); Actually, left shift also results in undefined behavior for positive signed values if the resulting mathematical value (which isn't limited in bit size) can't be represented as a positive value in that signed type. The bottom line is that you have to tread carefully when right shifting a signed value. @MichaelBurr: I know that hypermodern compilers use the fact that behavior that wasn't defined by the C standard (even though it had been defined in 99% of implementations) as a justification to turn programs whose behavior would have been fully defined on all platforms where they could be expected to run, into worthless bunches of machine instructions with no useful behav...
