The function called itself is called recursion. For example, a factorial program

int factorial(int number) {
 if(number == 0) {
 return 1;
 }
 factorial_i(number, 1);
}
int factorial_i(int currentNumber, int sum) {
 if(currentNumber == 1) {
 return sum;
 } else {
 return factorial_i(currentNumber - 1, sum*currentNumber);
 }
}
