# C Exercises: Calculate the power of any number

## C Recursion : Exercise-17 with Solution

Write a program in C to calculate the power of any number using recursion.
Test Data :
Input the base value : 2
Input the value of power : 6
Expected Output :

`The value of 2 to the power of 6 is : 64 `

C Code:

```#include <stdio.h>

long int CalcuOfPower(int x,int y)
{
long int result=1;
if(y == 0) return result;
result=x*(CalcuOfPower(x,y-1));  //calling the  function CalcuOfPower itself recursively
}
int main()
{
int bNum,pwr;
long int result;
printf("\n\n Recursion : Calculate the power of any number :\n");
printf("----------------------------------------------------\n");

printf(" Input the base  value : ");
scanf("%d",&bNum);

printf(" Input the value of power : ");
scanf("%d",&pwr);

result=CalcuOfPower(bNum,pwr);//called the function CalcuOfPower

printf(" The value of %d to the power of %d is : %ld\n\n",bNum,pwr,result);

return 0;
}
```

```#include <stdio.h>

long int CalcuOfPower(int x,int y)
{
long int result=1;
if(y == 0) return result;
result=x*(CalcuOfPower(x,y-1));  //calling the  function CalcuOfPower itself recursively
}
int main()
{
int bNum,pwr;
long int result;
printf("\n\n Recursion : Calculate the power of any number :\n");
printf("----------------------------------------------------\n");

printf(" Input the base  value : ");
scanf("%d",&bNum);

printf(" Input the value of power : ");
scanf("%d",&pwr);

result=CalcuOfPower(bNum,pwr);//called the function CalcuOfPower

printf(" The value of %d to the power of %d is : %ld\n\n",bNum,pwr,result);

return 0;
}```
