Enter row or col using _ or | followed by
the row or column you wish to sort
(row [0-11), col [0-5]): _ 0
Exit - y or n n
Enter row or col using _ or | followed by
the row or column you wish to sort
(row [0-11), col [0-5]): _ 1
Exit - y or n

when I input the character which is the underscore, and the row # it should display the table and sort that specific row. Why is the if statement skipped? This is not the complete program but has everything needed.

You never change your rORc (or sizerc) variables. You are passing variables by value. That means an independed copy is crated for use in functions and changing it will not change originls. You may use return value or pass by reference to achieve what you want.

Okay I understand. Thanks a lot MiiNiPaa, I really appreciate the help. Still learning you know.
