Integer power

What i gotta do:

Write a function called "integerPower(base, exponent)" that calculates and then returns the value of base to the power exponent. For example, if you invoke the function in the following manner:

integerPower(3,4);

the function should return the value 81 (3 * 3 * 3 * 3 = 81). Assume that "exponent" is a positive nonzero integer and that "base" is an integer. You should use type "long" to represent the exponent and base. The function should return a "long" value as well. Do NOT use any math library functions as part of your solution.

Write a main() function to use (and test) your integerPower() function. Your main() function should request a base and exponent value from the user and then invoke the function with the values provided by the user.

As a general rule, it is prefered that you NOT input or output (scanf or printf) from inside a function. By having the calling program (main() in our case) do all the input and output, your function remains more general purpose.



What i got .... cant seem to get the function workin properly

Code:

---

#include <stdio.h>

long integerpower( long base, long exponent );

int main()
{
        long base;
        long exponent;

        printf("\nEnter the base value: ");
        scanf("%d", &base);

        do{
                printf("Enter the exponent value(must be a positive integer): " );
                scanf("%d", &exponent);
                if(exponent<0){
                printf("\nInvalid data entered, try again!\n" );               
                }
        }        while(exponent<0);

        printf("%d raised to the power %d is: %d\n\n", base, exponent , integerpower);
        return 0;
}

long integerpower(long base, long exponent)
{
  if (exponent == 1)
    return base;
  else
    return(base * integerpower(base, exponent -1));
}

---

Code:

---

  printf("%ld raised to the power %ld is: %ld\n\n", base, exponent,
          integerpower(base,exponent));

---

Easy as pie sir.:)

Code:

---

#include <stdio.h>

int Power(int base, int pow){
//Special Cases:
    if (pow == 0) {return 1;}
    if (pow < 0)  {return 0;}  //No negative power is an integer

    int result=1;
        for(int i=0;i<pow;i++){
              result *= base;
        }
    return result;
}
           
int main(){
    printf("%d\n",Power(5,3));
    getchar();
    return 0;
}

thx bro....... haha wut a simple mistake ..... awell thx for the correction
