I’m trying to run this for loop;
for (int col= 0; grid[0].length; col++)
However every time I try to compile I get an error stating ‘incompatible types – found int but expected boolean’
I can’t work out what I’m doing wrong!
the second statement: grid[0].length is an integer. The second statement in a for loop is a condition statement and needs to be a boolean.
If you’re trying to loop while col is less than the length of grid[0], then you need this as your second statement:
col < grid[0].length;
