pratima sharma so you want to calculate x^y, but avoid using a predefined function, like pow()?

If the answer to my question is yes, than as voja 🏊♂️ said try using for loop and continue multiplying the number x with itself until you got the y number of multiplications.

int y = 5;
int x = 2;
int x2 = x;
for(int i = 0; i < y; i++){
x = x * x2;
}
cout << x << endl;

pratima sharma i check it out myself and it worked just fine, this is the code:
c++
#include <iostream>
using namespace std;
int main() {
int y = 5;
int x = 2;
int x2 = x;
for(int i = 0; i < y-1; i++){
x = x * x2;
}
cout << x << endl;
return 0;
}
