C Functions

All C programs has at least one function, which is main() ,  and all the most simple programs define more functions. A function is a group of statements that together perform a task. You can divide up your code into separate functions. How you divide up your code among different functions is up to you, but logically the division is such that each function performs a specific task. A function declaration tells the compiler about a function's name, return type, and parameters. A functi...

C Recursion

Recursion in programming is the process of calling a procedure repeatedly in a self-similar way, a recursive function or routine is a function that call itself repeatedly. void recursion() { recursion(); /* function calls itself */ } int main() { recursion(); } The C programming language supports recursion, i.e., a function to call itself. But while using recursion, programmers need to be careful to define an exit condition from the function, otherwise it will go into an...
