Question

PA 9-1 (25 points) Use nested loops to create a 11x11 grid like the one below. Tab in to start each row. Each cell is one row tall and three spaces wide. Dash (-) characters (45) were used to construct the horizontal lines. Using the rand function (hint: rand()%15) fill in all the cells in the grid with characters from ASCII number 33 (!) to 47(/). For full credit, use nested loops and center the digits in cells. Hint: for loops work best.

#include <iostream>
#include <cstdlib>
#include <ctime>

using namespace std;

int main() {
    srand(time(NULL));
    int num;
    for (int i = 0; i < 11; ++i) {
        for (int j = 0; j < 11; ++j) {
            num = 33 + (rand() % 15);
            cout << (char) num << "  ";
        }
        cout << endl;
        for (int j = 0; j < 11; ++j) {
            cout << "---";
        }
        cout << endl;
    }
    return 0;
