Hint: use for/while loop or recursion

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.

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; }
