In this tutorial, we are going to learn to write a C program to calculate the power of any given number.
So to calculate power we require at least two numbers. One number is known as a base number and another number is known as an exponent.
Let’s see how it works.
For example, we want to calculate the 4 to the power 5.
In mathematical representation, we can represent the above statement as 4^5.
Here,
Base = 4
Exponent = 5
And the operation that happens to calculate power is
4^5 means five-time multiplication of 4
4*4*4*4*4 = 1024
How our program will behave?
- Our program will take two integer inputs. One number will be base and another will be an exponent.
- And to calculate Power we will use pow() method of C which is in built method present in Math.h.
- pow(base, exp) , takes two parameter one is the base number for which we have to calculate power. And exp is the value of power.
- If we have to calculate 3^5, pow function will look like pow(3,5)
Program in C to calculate the Power of number using pow() function
#include <math.h>
#include <stdio.h>
int main() {
int base, exp, result;
printf("Program to calculate Power of given number\n");
printf("Enter a value of base: ");
scanf("%d",&base);
printf("Enter a value of exponent: ");
scanf("%d",&exp);
result = pow(base, exp);
printf("%d to the power %d is = %d", base, exp, result);
return 0;
}
Output
Program to calculate Power of given number
Enter a value of base: 3
Enter a value of exponent: 3
3 to the power 3 is = 27
