Question

**C++ only using recursion, no vectors classes, or global variables

*put #1 and #2 in the same program and print using a recursive function

1) Write a function to fill an array of size 32 with values 1 to 32 recursively

2) Write a function to fill an array of size 32 with values 32 to 1 recursively

Answer 1

#include<iostream>

using namespace std;

//to fill values 1 to 32
void fill_1(int* A, int size, int value)
{
if(size < 1)
return;
A[size - 1] = value;
fill_1(A, size - 1, value - 1);
}

//to fill values 32 to 1

void fill_2(int* A, int size, int value)
{
if(size < 1)
return;
A[size - 1] = value;
fill_2(A, size - 1, value + 1);
}

void print(int* A, int size)
{
if(size < 1)
return;
print(A, size - 1);
cout<<A[size - 1]<<" ";
}
int main()
{
int A1[32], A2[32];
fill_1(A1, 32, 32);
fill_2(A2, 32, 1);
print(A1, 32);
print(A2, 32);
return 0;
}
