Question

This code is based on creating a recursive funciton. You cannot alter the code besides adding your solution in the particular area.

Write code to complete PrintFactorial()'s recursive case. Sample output if userVal is 5:

5! = 5 * 4 * 3 * 2 * 1 = 120

#include

void PrintFactorial(int factCounter, int factValue){
   int nextCounter = 0;
   int nextValue = 0;

   if (factCounter == 0) {            // Base case: 0! = 1
      printf("1\n");
   }
   else if (factCounter == 1) {       // Base case: print 1 and result
      printf("%d = %d\n", factCounter, factValue);
   }
   else {                             // Recursive case
      printf("%d * ", factCounter);
      nextCounter = factCounter - 1;
      nextValue = nextCounter * factValue;

      /* YOUR SOLUTION GOES HERE*/

   }
}

int main(void) {
   int userVal = 0;

   userVal = 5;
   printf("%d! = ", userVal);
   PrintFactorial(userVal, userVal);

   return 0;
}

Answer 2

#include <stdio.h>

void PrintFactorial(int factCounter, int factValue){
int nextCounter = 0;
int nextValue = 0;

if (factCounter == 0) { // Base case: 0! = 1
printf("1\n");
}
else if (factCounter == 1) { // Base case: print 1 and result
printf("%d = %d\n", factCounter, factValue);
}
else { // Recursive case
printf("%d * ", factCounter);
nextCounter = factCounter - 1;
nextValue = nextCounter * factValue;

/* YOUR SOLUTION GOES HERE*/
return PrintFactorial(nextCounter, nextValue);

}
}

int main(void) {
int userVal = 0;

userVal = 5;
printf("%d! = ", userVal);
PrintFactorial(userVal, userVal);

return 0;
}

Output :
