Write a program that reads a list of integers, and outputs those integers in reverse.

Question

Write a program that reads a list of integers, and outputs those integers in reverse. The input begins with an integer indicating the number of integers that follow. For coding simplicity, follow each output integer by a space, including the last one.

Ex: If the input is:

5 2 4 6 8 10

the output is:

10 8 6 4 2

To achieve the above, first read the integers into a vector. Then output the vector in reverse.

#include <iostream>

#include <vector> // Must include vector library to use vectors

using namespace std;

int main() {

vector<int> userInts; // A vector to hold the user's input integers

/* Type your code here. */

return 0;

}

Answer 1

using namespace std;

#include <iostream>

int Go()

{

int N;

int A[20];

cout << " How many integers do you have ??? :>";

cin >> N;

if (N>20) { N=20; }

for (int iLoop=0; iLoop<N; iLoop++)

{

cout << "Input integer # " << (iLoop+1) << " :>";

cin >> A[iLoop];

}

for (int iLoop=N-1; iLoop>=0; iLoop--)

{

cout << A[iLoop] << " ";

}

cout << endl;

}

int main()

{

Go();

}
