Why do we use in C?

By learning C, you will be able to understand and visualize the inner workings of computer systems (like allocation and memory management), their architecture and the overall concepts that drive programming. As a programming language, C will also allow you to write more complex and comprehensive programs.

What is main () in C?

A main() function is a user-defined function in C that means we can pass parameters to the main() function according to the requirement of a program. A main() function is used to invoke the programming code at the run time, not at the compile time of a program.

Why we use void main in C?

The void main() indicates that the main() function will not return any value, but the int main() indicates that the main() can return integer type data.
