I have a programming assignment for CSCI180. The assignment is to create a recursive function power(base, exponent) that when invoked returns base ^ exponent. Everything compiles correctly and when i run the program i enter the base and exponent like prompted. But then the program stops working and i cannot determine why.
Here is the code i have. help would be greatly appreciated.
#include <stdio.h>
int power(int base,int exponent);
int main( void )
{
int choice;
int base;
int exponent;
do{
printf("enter a number and an exponent.\n");
scanf("%d,%d", &base, &exponent);
printf("%d raised to the %d is %d.\n", base, exponent, power(base,exponent));
printf("would you like to enter another power?\n");
printf("please type (1 = yes, 2 = no)\n");
scanf("%d", &choice);
}while ( choice != 2 );
return 0;
}
int power( int base, int exponent)
{
if (exponent==1){
return base;
}
else {
return base * power(base, exponent-1);
}
if (exponent < 0)
return 1/base * power(base, exponent-1);
}
