These are all in the language Qbasic
– Using nested FOR loops, write a program BOX to do the following:
Ask the user how wide and how long a box to print. (Ask for numbers in the range 1-20.)
Print a “box” that displays Xs. It should have as many Xs across as the user specified as wide and as many lines down as the user specified as long.
For example, if the user said 10 wide and 3 long, you would print the following box:
XXXXXXXXXX
XXXXXXXXXX
XXXXXXXXXX
-------------
– Using a FOR loop and the LOCATE statement, write a program DIAGONAL to do the following:
Print an X at row 1, column 1. Then print an X at row 2, column 2. Then one at row 3, column 3. And so on, through row 20, column 20.
After you print each X, use a timing delay loop to delay printing so you can see the staggered printing. The timing delay loop should be:
FOR t& = 1 TO 300000
NEXT t&
-----------
– EXTRA CREDIT: Write a program MOVING to do the following:
“Move” an X across the screen on row 10.
Hint: In addition to printing each new X in the next column to the right and using the timing delay loop, you need to “erase” the previous X by overwriting it with a space.
– EXTRA CREDIT: Write
a program DOWN to do the following:
“Move” the words GOING DOWN “down” the screen, from row 2 to row 18.
