#123762 - Uninitialised? Responding to: ???'s previous message |
Jon Ledbetter said:
temp = temp * 10 + key; For this to work, you need to ensure that temp is set to zero at the start of your function. You didn't show the initialisation; if it's really not there, the behaviour becomes pretty much undefined. The thing with "undefined" behaviour is that it can sometimes look like "correct" behaviour - so it might be just pure luck that gives you the "right" answer when you define it as 'char' rather than 'int'... |
