Finding power of a number in C, C++, Java and python
Program to find the power of a number is discussed here. Power of the number is the base raised to its exponent value. Power of a number can be found using loops, using recursion and also using library functions.
Program to find power of a number using pow() function
C
#include <math.h>
int main()
{
int base, exponent;
printf(“\nEnter the base value : “);
scanf(“%d”, &base);
printf(“\nEnter the exponent value : “);
scanf(“%d”, &exponent);
int result = pow(base,exponent);
printf(“\nResultant value : %d\n”, result);
return 0;
}
C++
#include
#include <math.h>
using namespace std;
int main()
{
int base, exponent;
cout << “\nEnter the base value : “;
cin >> base;
cout << “\nEnter the exponent value : “;
cin >> exponent;
int result = pow(base,exponent);
cout << “\nResultant value : ” << result>
return 0;
}
JAVA
// Java program to find the power of a number using recursion
import java.util.*;
public class Main
{
public static void main (String[] args)
{
int base,exponent;
Scanner sc = new Scanner(System.in);
System.out.print(“\nEnter the base value : “);
base = sc.nextInt();
System.out.print(“\nEnter the exponent value : “);
exponent = sc.nextInt();
int result = (int)Math.pow(base, exponent);
System.out.println(“\nResultant value : ” + result);
}
}
PYTHON 3
base = int(input(“Enter the base value : “))
exponent = int(input(“Enter the exponent value : “))
print(“Resultant value :”,int(pow(base, exponent)))
Output
Input- Enter the base value :3 Enter the exponent value :6 Output- Resultant value : 729
Program to find the power of a number using while loop
C
// C program to find power of a number using loops
#include
int main()
{
int base, exponent;
long int result = 1;
printf(“\nEnter the base value : “);
scanf(“%d”, &base);
printf(“\nEnter the exponent value : “);
scanf(“%d”, &exponent);
while(exponent != 0)
{
result = result * base;
–exponent;
}
printf(“\nResultant value : %d\n”, result);
return 0;
}
