C++ Recursion1 min read

Recursion refers to the process when a function calls itself inside that function directly or indirectly or in a cycle. And such functions are called recursive functions. However, the crucial part is the termination condition, if not handled properly then it might go into an infinite loop.


We can use the if…else statement to stop it from going into an infinite loop. Using the if…else statement, one branch of if-else can call the function itself and the other can give the condition to end the function.
