Compute Power of a Number

“Compute Power of a Number” is again basic problem of programming for beginners. Here, we are given a base and exponent number, entered by users and our task is to write a program to compute the power of a number, base^exponent.

2³ = 2 * 2 * 2 = 8

Example (Compute Power of a Number)

INPUT:
Base = 2, Exponent = 3
OUTPUT:
8

To compute the power of a number, simply loop can be used.

C++ Program to Compute Power of a Number is as follows:

/* C++ Program to Compute Power of a Number */
#include<bits/stdc++.h>  
using namespace std;  
int main()  
{  
    //Scan the base and exponent  
    int base,exponent;  
    cout<<"Enter the base and exponent:";  
    cin>>base>>exponent;  
      
    // Compute the Power  
    int Power = 1;  
    for(int i = 1 ; i <= exponent ; i++)  
    {  
        Power = Power * base;  
    }  
      
    // Printing the result  
    cout<<Power;  
}  

OUTPUT:
Enter the base and exponent: 2 3
8
