It is a function to call itself. if a program allows you to call a function inside the same function, then it is called a recursive call of the function

In programming languages, if a program allows you to call a function inside the same function, then it is called a recursive call of the function. void recursion() { recursion(); /* function calls itself */ } int main() { recursion(); }

In a programming language, if you can call the same function from itself, then the programming language supports recursion. There are many problems which can be solved by recursion as it's very intuitive. For example, factorial of a number can be defined in terms of factorial(n) = factorial(n -1) * factorial(n-2) * factorial(n-3).... factorial(2) * factorial(1). As you can see, you can write the factorial of a given number using a recursive function. Here is a C snippet for the same. int fact(n) { if ( n == 1) { return 1; } else { return n * fact(n -1); } } read less

When a function call itself is known as recursion. for example if you want to add subsequent numbers in a list let a = and your o/p should be then you need to use recursion for such kind of problem

A function calling itself is called a recursive function and the methodology is called recursion. To break the calling of the function, a condition is provided. Different languages use different syntax to achieve recursion.
