Basic Fail #1

for (int t; t<n; t++) {
    ...
}

... Forgetting to initialise the variable in a for loop.

In the above example, if t is not initialised to anything then the program will still compile and run, but display odd behaviour. I seem to be doing this a lot recently - it can be tricky to track down and just infuriated me for half an hour. Oops.
