advanced use of the IF statement

Hey GDers! I have an extremely tedious task for you. I have an IF statement with a LOT of parentheses (29x2 pairs!). The problem is that my compiler (Borland C++ Builder 3) gives me errors ("Expression syntax", "If statement missing )" and "Compound statement missing }" ) Sound like a n00b problem? Perhaps it is and people use IF like this all the time, but is it possible to go overboard like I did here? if( ( ( (x1 <= x ) && (x2 => x) ) || ( (x2 <= x) && (x1 => x) ) ) && ( ( (line->x1 <= x) && (line->x2 => x) ) || ( (line->x2 <= x) && (line->x1 => x) ) ) && ( ( (y1 <= y) && (y2 => y) ) || ( (y1 >= y) && (y2 <= y) ) ) && ( ( (line->y1 <= y) && (line->y2 >= y) ) || ( (line->y1 >= y) && (line->y2 <= y) ) ) ) { return true; } This block of code checks that the bounds of x are within x1 and y1 and within line->x1 and line->x2, and that the bounds of y are within y1 and y2 and within line->y1 and line->y2. a) Is this a legal use of IF, and if so, why am I getting errors with it? b) Is there a simpler way of doing this?
