Power of Any Number Without Using In-Built Function.

Welcome to Codingfizz,

In this article, we will print the power of any number without using pow() or an in-built function in C, C++, and Java programming languages.

pow() function is used to return the power of any number. pow() is an in-built function. 

Example:

With pow() function

Input:

a = 2, b= 2

pow(2, 2);

Output:

4

Program to print the power of any number without the pow() function in C.

 #include <stdio.h>

 int main()
 {
    int a, b, i;
    int power =1;
    scanf("%d %d",&a,&b);
    
    for(i=0; i<b; i++){
        power = power*a;
    }
    printf("%d",power);

    return 0;
 }

Output:

2 3

Program to print the power of any number without the pow() function in C++.

 #include <iostream>

 using namespace std;

 int main()
 {   
    int a, b, i;
    int power =1;
    cin>> a>>b;
    
    for(i=0; i<b; i++){
        power = power*a;
    }
    
    cout<<power;

    return 0;
 }

Output:

2 3

Program to print the power of any number without the pow() function in Java.

 public class Main
 {
 	public static void main(String[] args) {
 	    
 	    int a=2, b=3, i;
        int power =1;
        
        for(i=0; i<b; i++){
        power = power*a;
        }
        
 		System.out.println(power);
 	}
 }

Output:

2 3
