Small Steps I — Creating with Text and Numbers

Drawing several rows of stars

Draw three rows with four stars each.

What you will learn

You can put a loop inside another loop. The outer loop counts rows; the inner loop counts the stars in each row.

Try it

void small_main()
{
    for (int row = 0; row < 2; row = row + 1)
    {
        for (int col = 0; col < 3; col = col + 1)
        {
            write("*");
        }
        print();
    }
}

write does not move to a new line after output. print() moves to a new line without printing content. The program therefore prints three adjacent stars and then a newline, twice.

Expected output:

Exercise

Draw three rows with four stars each.

void small_main()
{
    for (int row = 0; row < 2; row = row + 1)
    {
        for (int col = 0; col < 3; col = col + 1)
        {
            write("*");
        }
        print();
    }
}

Hint

Change the parts of the example that you need.

void small_main()
{
    for (int row = 0; row < 3; row = row + 1)
    {
        for (int col = 0; col < 4; col = col + 1)
        {
            write("*");
        }
        print();
    }
}
