Question

This is my second C assignment and we have been told to recreate a version of Conway’s Game of Life. I am using a struc (typedef) to hold my 2d array of ints for the grid created with:

typedef int TableType[HEIGHT][WIDTH];

HEIGHT & WIDTH are #define constants.

I am trying to use the function below to compare 2 tables. With the following error (no matter what way I try and compare the values):

error: expected expression before '==' token


int compareTables (TableType tableA, TableType tableB){
    int height, width;
    for (height = 0; height < HEIGHT; height++) {
        for (width = 0; width < WIDTH; width++) {
        if(tableA[height][width]) == tableB[height][width])
        return LIFE_NO;
        }
    }
    return LIFE_YES;
}

I am using Code-Blocks as my compiler and can’t seem to find a way to get gccx to work. So, as far as I know ‘stdio.h’ is the only library I can use.

I’ve tried importing pointers and manipulating those with the -> operator to get the values to compare to no avail.
I also use a similar method to copy tables and it seems to compile fine.

Any suggestions??
Please be gentle I’m a nOOb.

Thanks in advance.

Answer 1

if(tableA[height][width]) == tableB[height][width])

should be

if(tableA[height][width] == tableB[height][width])
