Question

#include <iostream>
using namespace std;

void drawRect(int h, int w) {}

int main() {}

Write a program that produces h x w rectangles comprised of alternating columns of 1's and 0's (where h and w all user-specified).

For example:

Enter the desired dimensions for a rectangle: 6 4

Result:

Answer 1

#include <iostream>
using namespace std;

void drawRect(int h, int w) {
    int n = 1;
    for (int i = 0; i < h; ++i) {
        for (int j = 0; j < w; ++j) {
            cout << n;
            n = (n+1)%2;
        }
        cout << endl;
    }
}

int main() {
    int h, w;
    cout << "Enter the desired dimensions for a rectangle: ";
    cin >> h >> w;
    drawRect(h, w);
    return 0;
