    Arrays and functions

    I've only been learning c for a week or two and i'm currently doing an assignment to find the line of best fit for a number of user set co-ordinates.
    i am having trouble setting up a function to sum one of the columns of a two column array. especially what arguments i'm meant to use.

    any help would be GREATLY appreciated

    Too little information. Can you provide a code snippet?

    If the OP doesn't even know what arguments to use, probably not.

    So you have something like this:
    Code:
    int array[2][number];
    and you have to add all the numbers in array[0] or array[1]? Well, your prototype could look something like this:
    Code:
    int add_col(int array[], int size_of_array);
    
    /* function call */
    int array[2][100];
    printf("%i\n", add_col(array[0], 100));
