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
```
