# C++ program to find the Power of a number

## Program to find the Power of a number

Here we will discuss how to find the power of a number using C++ Programming language.

To calculate the power of a number we need the two inputs – base and exponent. These two inputs are passed into a function, pow(input1,input2), as parameters and it will return the power of the number(base). The function is present in the math.h header file.

For Example: Base5 ,  Exponent 3

pow(Base, Exponent) = pow(5, 3)

= 125 ### Working

Let’s see how the code works:

• User gives two inputs.
• Inputs are stored in two double type variable say base & exp.
• A function, pow(base, exp) is called with base and exp as parameters.
• The calculated power is stored in another variable say res.
• res is printed with precision set up to 2 decimal places.

### C++ Code

`//C++ Program//Power of a number#include <iomanip>#include <iostream>#include <math.h>using namespace std;//main programint main() {    double exp, base;    cout<<"Enter base: ";    //user input 1    cin>>base;    cout<<"Enter Exponent: ";    //user input 2    cin>>exp;    //calculating power using function    double res = pow(base, exp);    //printing result    cout << base << "^" << exp << " = " ;    cout << fixed <<setprecision(2)<<res<<endl;    return 0;}`

#### Output

`Enter base: 123Enter Exponent: 3.5123^3.5 = 20638013.40`
