Write a C Program to Find power of a number using recursion.

1. #include<stdio.h>
2. #include<conio.h>
3. 
   
4. int main() {
5. int pow,no;
6. long int res;
7. long int power(int,int);
8. printf("Enter a number: ");
9. scanf("%d",&no);
10. printf("\n Enter power: ");
11. scanf("%d",&pow);
12. res=power(no,pow);
13. printf("\n%d to the power %d is: %ld",no,pow,res);
14. return 0;
15. }
16. int i=1;
17. long int sum=1;
18. long int power(int num,int pow) {
19. if(i<=pow) {
20. sum=sum*no;
21. power(no,pow-1);
22. } else
23. return sum;
24. }

OUTPUT:

Enter a number: 5

Enter power: 2

5 to the power 2 is: 25
