    array

    How can I put a range of numbers in an array without typing in all the numbers. Like 0-24,25-49,50-74,75-100

    I tried;

    Code:
    int x[] = {0-24,25-49,50-74,75-100};
    Is that a legal statement?

    any sugguestions?

    Thanks

    You don't. Try either building a vector at runtime or using paired numbers for the minimum and maximum of the range:
    Code:
    int x[] = {
            0,  24,
            25, 49,
            50, 74,
            75, 100,
    };

    Hey twm - chill on the sig man. Most people here are very cool and some of the best people you'll ever meet on a board. It's all good.


    Usually you load an array from disk if you have a lot of numbers to put into it. Unfortunately there is no DATA like BASIC keyword that allows you to put data directly into the data segment and then retrieve it with a READ.

    I'm not sure if this is what you wanted, but uhm, for loop?
    Code:
    for(int i =0; i < max; ++i)
      array[i] = i;

    You could use a 2d array, something like:
    Code:
    int array[4][25] ;
    for (int x=0;x<4;x++)
     for(int y=0;y<25;y++)
       array[x][y] = y*(x+1);
    Note I didn't test this code
