Just as a practice, I am working on an app that solves the famous middle school pythagorean theorem, a squared + b squared = c squared. Unfortunately, the out-coming answer has, in my eyes, nothing to do with the actual answer. Here is the code used during the "solve" action.
- (IBAction)solve {
int legoneint;
int legtwoint;
int hypotenuseint;
int lonesq = legoneint * legoneint;
int ltwosq = legtwoint * legtwoint;
int hyposq = hypotenuseint * hypotenuseint;
hyposq = lonesq + ltwosq;
if ([legone.text isEqual:@""]) {
legtwoint = [legtwo.text intValue];
hypotenuseint = [hypotenuse.text intValue];
answer.text = [NSString stringWithFormat:@"%d", legoneint];
self.view.backgroundColor = [UIColor blackColor];
}
if ([legtwo.text isEqual:@""]) {
legoneint = [legone.text intValue];
hypotenuseint = [hypotenuse.text intValue];
answer.text = [NSString stringWithFormat:@"%d", legtwoint];
self.view.backgroundColor = [UIColor blackColor];
}
if ([hypotenuse.text isEqual:@""]) {
legoneint = [legone.text intValue];
legtwoint = [legtwo.text intValue];
answer.text = [NSString stringWithFormat:@"%d", hypotenuseint];
self.view.backgroundColor = [UIColor blackColor];
}
}
By the way, legone, legtwo, and hypotenuse all represent the UITextField that corresponds to each mathematical part of the right triangle. Answer is the UILabel that tells, you guessed it, the answer. Does anyone see any flaws in the program? Thanks in advance!
