Yes it is possible to call function inside itself. This is called recursion.
Each time function will be call and parameter value will be change until you don't break function at some point.
This code is running continuously till infinity because of count == 0
Do count <= 0

You can get factorial of number using recursion.
Factorial of 5
------------
#include<stdio.h>
int printFact(int count);
int main () {
printf("%d", printFact(5));
return 0;
}
int printFact(int count) {
if(count <= 1)
return 1;
//printf ("Hello\n");
return count * printFact(count - 1);
}
