What is the correct way to call a function

When a function is called by passing values in the argument, it's called called by value, but what kind of function call is done when no values are passes? What kind of function call can we call it if it's not call by value or reference? Example: #include int add(); int text(); int main() Output: Sum of two numbers is 3 In this program the add() function is called by passing values and we can say that it has been called by passing value but what can we call the text() function? How it is called?

Suppose, you need to create a program to create a circle and color it. You can create two functions to solve this problem: • create a circle function • create a color function Dividing a complex...

In this article If you're writing PowerShell one-liners or scripts and find yourself often having to modify them for different scenarios, there's a good chance that it's a good candidate to be turned into a function that can be reused. Whenever possible, I prefer to write functions because they are more tool oriented. I can put the functions in a script module, put that module in the $env:PSModulePath, and call the functions without needing to physically locate where they're saved. Using the PowerShellGet module, it's easy to share those modules in a NuGet repository. PowerShellGet ships with PowerShell version 5.0 and higher. It is available as a separate download for PowerShell version 3.0 and higher. Don't over complicate things. Keep it simple and use the most straight forward way to accomplish a task. Avoid aliases and positional parameters in any code that you reuse. Format your code for readability. Don't hardcode values; use parameters and variables. Don't write unnecessary code even if it doesn't hurt anything. It adds unnecessary complexity. Attention to detail goes a long way when writing any PowerShell code. Naming When naming your functions in PowerShell, use a -. In PowerShell, there's a specific list of approved verbs that can be obtained by running Get-Verb. Get-Verb | Sort-Object -Property Verb Verb Group ---- ----- Add Common Approve Lifecycle Assert Lifecycle Backup Data Block Security Checkpoint Data Clear Common Close Common Compare Data Complete Lifec...

You can call by name: function_name(args); You can call by function pointer: void (*function_pointer)(int, char *) = ...; (*function_pointer)(3, "moo"); // classic function pointer syntax function_pointer(3, "moo"); // alternate syntax which obscures that it's using a function pointer No, you cannot call a function without using (). You can hide the () by using a macro but that just hides where they are; in the end you must use () somewhere. There are several pedantic ways to invoke a function without using (). Naming the function "main" (with correct parameter & return types) is one good way. You could register it as an interrupt handler. You could trick the compiler into jumping into it by smashing the stack ( not portable and not recommended, works with gcc on 64-bit x86): #include void foo() Thanks for contributing an answer to Stack Overflow! • Please be sure to answer the question.
