    Question about arrays?? PLease read..

    Ok, I'm not an expert here of course but I'm having a difficult time with array's. Here's the question...

    User enters in a number regarding how many inputs to be entered (ie. 2.3, 4.5, 2.0). Then the user is asked to enter a number 1-10. Now what this number does is starts at the predetermined array and goes back wards to the beginning.

    EX:
    Enter X: (user puts 4)
    Enter Y: (user puts 3)

    output:
    Enter number 1: (user input 2.0)
    Enter number 2: (user input 3.4)
    Enter number 3: (user input 1.1)
    Enter number 4: (user input 2.9)

    break

    The last three numbers you have entered are: 2.9, 1.1, 3.4

    How in the world can I start at a specific array and go backwards? Hope you can help.

    Code:
    for (i = 10; i >= 0; i--)
    {
    	printf ("Array element %d is %d\n", i, myarray[i]);
    }
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    Keep in mind that arrays go from: 0 to Size-1.

    Thus, if you do:

    int array[10];

    You access the elements as:

    array[0] = 1;
    ...
    array[9] =10;

    Hope is the first step on the road to disappointment.

    >myarray[11];
    When all else fails, read the instructions.
