    A space char is ascii 32 on most PC's. If you don't have an ascii table yet, you can easily download one from the net. Very handy for anyone who programs.

    If you mean a null char, then it's just '\0'. For both the form in general is
    Code:
    for(row=0;row<R;row++) {//R=3 in your example
       for(col=0;col<C;col++) { //C=3  "   "      "
            and assign your char array[row][col] the value of either '\0' or 32
       }
    }

    No, don't go using magic numbers like 32. The only time you ever need an ASCII table is when debugging and looking at stuff in a memory viewer. If you're actually writing code then you should always be using actual characters.
    In this case a space was asked for, so that means assigning a space character, e.g.
    Code:
    loc[i][j] = ' ';
