    Array with input? please help..beginner

    I have std input thats says

    @ 3 4

    This means that I need to put an @ sign at slot 3 in my array, and slot 4. how do I do this using getline? im using ./exe <input as my command line argument, so my file 'input' looks like this

    @ 3 4
    % 5 12
    # 2 17

    so obviously i have a 2 dimensional array.. so.. array[i][j] = @ if i = 0 and j = 3.. right?
    how do i put this in a loop?

    Code:
    char buff[BUFSIZ];
    while ( fgets( buff, sizeof buff, stdin ) != NULL ) {
    }
    Reads from the keyboard, or from the file if you use <input on the command line.
    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.
