Hence we can say that main() in c programming is user defined as well as predefined because it’s prototype is predefined.

What is user define function in C?

A function is a block of code that performs a specific task. C allows you to define functions according to your need. These functions are known as user-defined functions. For example: Suppose, you need to create a circle and color it depending upon the radius and color.

What is main function in C?

What is function in C and its advantages?

Advantages of Function Avoid repetition of codes. Increases program readability. Divide a complex problem into simpler ones. Reduces chances of error. Modifying a program becomes easier by using function.

What is function advantage and disadvantage?

Definition of Function: … The idea behind a function is that it compartmentalizes part of the program, and in particular, that the code within the function has some useful properties. Advantages of Functions: i) The length of a source program can be reduced by using functions at appropriate places.

Why do we need functions in C?

Why we need functions in C a) To improve the readability of code. b) Improves the reusability of the code, same function can be used in any program rather than writing the same code from scratch. c) Debugging of the code would be easier if you use functions, as errors are easy to be traced.
