Posted on Dec 27, 2019

C program to find x raised to the power of y.

Program 

#include<stdio.h>
#include<conio.h>
#include<math.h>
void main()
{
	double num1, num2, power;

   	printf("Enter first number: ");
   	scanf("%lf",&num1);

	printf("Enter second number: ");
   	scanf("%lf",&num2);

   	power = pow(num1,num2);
   	printf("\n%lf raised to the power of %lf is: %lf",num1,num2,power);

	getch();
}

Output 

Enter first number: 4
Enter second number: 5

4.000000 raised to the power of 5.000000 is: 1024.000000

Explanation

In C, pow() function is used to find the power of any number. It is a library function of math.h header file.
Syntax for pow() function in C is as follows,
double pow (double base, double exponent);

In the above program, this function is used to find the power of a number.
For this, base value and exponent value are entered by the user, and received in variables 'num1' and 'num2' respectively. Power of a number is calculated using statement
pow(num1, num2)
and the result is stored in 'power' variable.

Note that %lf is the format specifier for double data type.
