Question
Replaces the "XXXXs" in the code below to complete the two functions.
You should repace the "XXXXXs" with some combination of:
cout << *n << endl;
recursivePrintForward(n+1, nCount-1);
recursivePrintBackwards(n+1, nCount-1);
if (nCount > 0){ }
////
#include <iostream>
using namespace std;
void recursivePrintForward(int *n, int nCount){
// *n is a pointer to an array of ints
// nCount is the number of items in the array
XXXX
XXXX
XXXX
}
void recursivePrintBackwards(int *n, int nCount){
// *n is a pointer to an array of ints
// nCount is the number of items in the array
XXXX
XXXX
XXXX
}
int main(){
int numbers[] = {10,20,30,40,50,60,70,80,90};
cout << "Testing recursivePrintForward:" << endl;
recursivePrintForward(numbers,9);
cout << "Testing recursivePrintBackwards:" << endl;
recursivePrintBackwards(numbers,9);
return 0;
}
Explanation / Answer
void recursivePrintForward(int *n, int nCount){
// *n is a pointer to an array of ints
// nCount is the number of items in the array
if (nCount==0)
{
return;
}
else
{
recursivePrintForward(n,nCount-1);
printf("%d",*(n+nCount-1));
}
}
void recursivePrintBackwards(int *n, int nCount){
// *n is a pointer to an array of ints
// nCount is the number of items in the array
if (nCount==0)
{
return;}
else{
recursivePrintBackwards((n+1),nCount-1);
printf("%d",*n);
}
}
