I need to write a program that reads an command prompt argument (int n) that then outputs a cross made of Xs depending on the number, so an arg of 3 would output this

X would increase or decrease depending on the number in the arg

im not really sure how to go about this

Answer 1

Here's an algorithm (not actual code) for printing the cross (assuming the argument passed in is referred to as count):

LOOP(count times)
    LOOP(count times)
        PRINT space_character
    ENDLOOP
    PRINT "X"
    PRINT newline
ENDLOOP

LOOP(count times)
    PRINT "X"
ENDLOOP

PRINT " "

LOOP(count times)
    PRINT "X"
ENDLOOP

PRINT newline

LOOP(count times)
    LOOP(count times)
        PRINT space_character
    ENDLOOP
    PRINT "X"
    PRINT newline
ENDLOOP

Answer 2

There are different ways to do this, the best way to start though is to break it up into loops.

So there would be a loop to create the first vertical section. Then one to produce the second horizontal and finally one to produces the last vertical section
