C program to find the power of a number. Write a C program to enter the base and exponents and calculate the power of a number using the pow function.

Write a C program to input base and exponent and calculate the power of the number using `pow()`

function.

To calculate power of a number we can use `pow()`

function which is available under `math.h`

header file.

This problem can also be solved using loops if we don't want to use `pow()`

function but we will see this later in loops section.

**Example -**

```
Input:
Enter base: 5
Enter exponent: 2
Output:
5.00 to the power 2.00 = 25.00
```

## C program to find power of a number

```
#include <stdio.h>
#include <math.h>
void main()
{
double base, exponent, power;
printf("Enter base: ");
scanf("%lf", &base);
printf("Enter exponent: ");
scanf("%lf", &exponent);
power = pow(base, exponent);
printf("%0.2lf to the power %0.2lf = %0.2lf", base, exponent, power);
}
```

**Output**

```
Enter base: 5
Enter exponent: 2
5.00 to the power 2.00 = 25.00
```

Here, `double`

data type is used to store data and calculate power of the number because the output could be a large number and `pow()`

returns `double`

type of data.

`0.2lf`

is used to print values upto 2 decimal places.
