power in c++

/* pow example */
#include <stdio.h>      /* printf */
#include <math.h>       /* pow */

int main ()

power function c++

#include <bits/stdc++.h>
using namespace std;
#define ll long long

ll power(ll a,ll b){
  ll ans = 1;
  while(b--){
    ans *= a;
  }
  return ans;
}

int main(){
  ll x,y;
  cin >> x >> y;
  ll x_power_y = power(x,y);
  cout << x_power_y << endl;
}

power in c++

double result = pow(x, y);

how to use power in c++

// CPP program to illustrate
// power function
#include <bits/stdc++.h>
using namespace std;
 
int main()
{
    double x = 6.1, y = 4.8;
 
    // Storing the answer in result.
    double result = pow(x, y);
 
    // printing the result upto 2
    // decimal place
    cout << fixed << setprecision(2) << result << endl;
 
    return 0;
}

pow c++

template<class T>T Pow(T n,T p) 
{ 
  T res = n; 
  for(T i = 1; i < p; i++)  
     res *= n;  
  return res; 
}
//Example: Pow(2,3) = 8

pow in c++

In C++, pow(a, b) = a^b
