Question

#include<iostream>
using namespace std;
int main()
{int a[5],b[5];
int i=0,j=4;
cout<<"enter elements";
for(i=0;i<5;i++)
{cin>>a[i];}
while(i<5&&j>=0)
{b[j]=a[i];
j--;
i++;
}
for(i=0;i<5;i++)
cout<<b[i];
return 0;
}

Answer 1

Try resetting the variable i to zero after the first for loop because it is be equal to 5 before the while loop is initiated.
Otherwise you could consolidate the first for loop and the while loop by doing something like:
int a[5], b[5];
int j = 4;
cout << "enter elements: " << endl;
for (int i = 0; i < 5; i++) {
cin >> a[i];
b[j] = a[i];
j--;
}
