    std::cin >> rows; 
    std::cout << "How many columns? "; 
    std::cin >> columns; 
    std::cout << "What character to display? "; 
    std::cin >> character; 
 
    std::cout << "\n"; 
    for (int i = 0; i < rows; i++) 
    { 
           for (int j = 0; j < columns; j++) 
           { 
                std::cout << character; 
           }
