What are inbuilt functions in C?

1) Predefined standard library functions Standard library functions are also known as built-in functions. Functions such as puts() , gets() , printf() , scanf() etc are standard library functions. These functions are already defined in header files (files with . h extensions are called header files such as stdio.

What is C function?

A function is a group of statements that together perform a task. Every C program has at least one function, which is main(), and all the most trivial programs can define additional functions. … A function declaration tells the compiler about a function’s name, return type, and parameters.

What is main function in C?

Every C program has a primary (main) function that must be named main. … The main function serves as the starting point for program execution. It usually controls program execution by directing the calls to other functions in the program.
