    Default If-goto Loop

    Hey guys,

    I have an assignment due for thursday and this is one of the questions

    Here is a for loop:
    1. for i equals 1 to 10
    2. an instruction
    3. another instruction

    Rewrite this loop in if-goto language.

    The problem is, I have no idea what if-goto language is :/ it;s really confusing me, hoping someone can offer me some help

    Default Re: Java question

    if-goto is what it sounds like:

    If something is true, goto somewhere else.

    For example:

    1. ask user for input
    2. if invalid input: Goto 1
    3. process input

    This will keep asking the user for inputs until what they enter is valid.

    In current programming practice goto should be avoided as it has a tendency to produce "spaghetti code" (code that's hard for humans to read/understand). It has it's uses and is a must in assembly/machine language, but you really shouldn't be programming at that level if you don't have to.

    Please don't post the same question under multiple categories. I've moved stuff around so you only have one thread.
