    2D Arrays

    Hi

    If i have a number sequence for Example
    1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17 and maximum columns in the array is 5. if i input the above then the program should display in 2D array formats as below choice for the use is to key board input the values.

    TABLE: 1 5 9 12 15
    2 6 10 13 16
    3 7 11 14 17
    4 8

    Output Image

    What have you tried?

    Also, think about what happens if the user inputs say 16 numbers, or 18 numbers.

    Or they choose a column number other than 5.

    Knowing what you're supposed to do in other cases helps to figure out the algorithm to solve all cases.

    For example, the number of 'long' columns is apparently 17 % 5 (which is 2). But is that just me, or what you really want?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
