    Xor

    Consider the following code:

    arraysum[coll][line] = arraysum[coll][line] ^ array[coll][line];

    Every variables are typed int and the arrays can only take 1 and 0 as values.

    My compiler reports an error:
    "operands of ^ have illegal types 'int' and 'pointer to int'"

    By the way, I use lcc-win32.

    Where is the error, the code or the compiler?

    What are the exact definitions of arraysum and array?
    Naturally I didn't feel inspired enough to read all the links for you, since I already slaved away for long hours under a blistering sun pressing the search button after typing four whole words! - Quzah

    aslo you know that can be shorthanded
    Code:
    arraysum[coll][line] = arraysum[coll][line] ^ array[coll][line];
    
    arraysum[coll][line]^=array[coll][line];
    of course once we help you figure out the error.

    Code:
    arraysum[coll][line] = arraysum[coll][line] ^ array[coll][line];
    Code:
    int array[21][4][4];
    int arraysum[4][4];
    You mean to say it isn't obvious what the problem is here?
