Void someFunction (const int b[], size_t startSubscript, size_t size) { if {startSubscript

Explanation / Answer

PART A:

#include <stdio.h>

//This function calculats the product of the integers a and b
unsigned int mystery(unsigned int a, int unsigned int b){

   //If b is 1, returning a
   if(1==b) return a;
  
   //Else adding a to the answer and decrementing b
   return a+mystery(a,b-1);
}
int main(void ) {
   unsigned int x;
   unsigned int y;
   printf("%s","Enter two positive integers: ");
   scanf("%d%d",&x,&y);
   printf("%d",mystery(x,y));
}

PART B:

#include <stdio.h>
#define SIZE 10

//This function prints the elements of the array in reverse order
void someFunction(const int b[], size_t startSubscript, size_t size){
   if(startSubscript < size){
       //Making a recursive call
       someFunction(b, startSubscript + 1, size);
       printf("%d",b[startSubscript]);
   }
}
int main(void ) {
   int a[SIZE] = {8,3,1,2,6,0,9,7,4,5};
   printf("Answer is : ");
   someFunction(a,0,SIZE);
   puts("");
}
