What is the definition of a function in C?

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 subroutine in 12th class?

What is a subroutine? Answer: Subroutines are the basic building blocks of computer programs. Subroutines are small sections of code that are used to perform a particular task that can be used repeatedly.

What happens when subroutine is called?

When a subroutine is called, program control is transferred from the main program to the subroutine. When the subroutine finishes executing, control is returned to the main program. The stack provides the means of connecting the subroutines to the main program.

What type of abstraction is subroutines?

What is prototype in C?

A function prototype is simply the declaration of a function that specifies function’s name, parameters and return type. It doesn’t contain function body. A function prototype gives information to the compiler that the function may later be used in the program.
