Functions allow us to break our program into smaller, more manageable subprocedures. Before using a function, we need to define it and optionally declare it explicitly. Although function declaration isn’t strictly required, omitting it may generate compiler warnings if the default declaration does n...

Main function – This function marks the start of any C program. It is a preset function that is first executed when a program is run. The main function may call other functions to execute specific tasks. Example: int main(void) { // code to be executed return 0; } Library functions...
In the Hello World program, we used the function printf, which prints the given message to the standard output. The printf function is a standard built-in function in C. So the compiler understands the action requested by the use of that function. But it is often necessary in programming t...
In this tutorial, we will learn functions in C programming. A function is a block of statements that performs a specific task. Let's say you are writing a C program and you need to perform a same task in that program more than once. In such case you have
A function exists in almost all programming languages. As the word suggests, a function is a group of statements clubbed together to perform a particular task. Each function is accompanied by a set of parenthesis, the opening bracket ( and the closing bracket ). There may be a group of var...
Explore the different categories of functions in C programming, including library functions, user-defined functions, and more to enhance your coding skills.
If a name that has not been previously declared occurs in an expression and is followed by a left parenthesis, it is declared by context to be a function name, the function is assumed to return an int, and nothing is assumed about its arguments. Furthermore, if a function declaration does...
