Question

1. implement a program that reads a number of rows and a symbol. The program will draw a square with the specified number of rows and the provided symbol. For example, if the user enters 5 as the number of rows and * as the symbol, the program will print the following diagram:

                   * * * * *
                   * * * * *
                   * * * * *
                   * * * * *
                   * * * * *

2. For this problem:
   • The square will be drawn by a function called drawRectangle that has the following prototype: function drawSquare(maxRows, symbol)
   • Write JavaScript code outside of the function that will read the number of rows using prompt and the message "Enter number of rows". The function will then read the symbol using prompt and the message "Enter symbol (e.g., *)". After reading this data, the code will call the drawSquare function.
   • Your program must work for different number of rows and symbols.

Answer 1

function drawSquare(maxRows, symbol) {
    for (var i = 0; i < maxRows; i++) {
        var s = "";
        for (var j = 0; j < maxRows; j++) {
            s += symbol + " ";
        }
        console.log(s);
    }
}

var rows = prompt("Enter number of rows");
var symbol = prompt("Enter symbol (e.g., *)");
drawSquare(rows, symbol);
