Description

To calculate the power of a number, the base and power is user input.
Here pow() function used for calculating the power.

C/C++

/* C Program to calculate power of a number */
//Save it as PowerOfNumber.c

#include<stdio.h>
int main(){

    double base, power;

    printf("Enter a base : ");
    scanf("%lf",&base);

    printf("Enter power : ");
    scanf("%lf",&power);

    double value = pow(base, power);

    printf("%lf^%lf = %lf",base,power,value);

    return 0;
}

Input:
Enter a base : 2
Enter power : 5

Output:
2.0^5.0 = 32.0

Java

/* Java Program to calculate power of a number */
//Save it as PowerOfNumber.java

import java.io.*;
import java.util.Scanner;

public class PowerOfNumber {

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);
        
        System.out.println("Enter a base : ");
        double base = scanner.nextDouble();
        
        System.out.println("Enter power : ");
        double power = scanner.nextDouble();
        
        double value = Math.pow(base, power);
        
        System.out.println(base+"^"+power+" = "+value);
    }
}

Input:
Enter a base : 
2
Enter power : 
5

Output:
2.0^5.0 = 32.0
