In programming we have recursion functions, these functions are the functions which call themselves in the same function.
In simple words if any function calls itself then it is known as recursion.

if(x != 0)
{
return x * fact(x-1);
}
else
{
return 1;
}
}
//itvoyagers.in
int main()
{
int num,rsl;
printf("Enter enter any number : ");
scanf("%d",&num);
rsl = fact(5);
printf("Factorial of %d is %d", num, rsl);
return 0;
//itvoyagers.in
}
Output :
Enter enter any number : 5
