This error is rather conf...

In the past I returned -1 when this error occurred, because I didn't need to convert strings to negative numbers. But now I want it to convert strings to negativ...

On occasion I've heard people discuss the benefits of keeping track of programming mistakes, if for no other reason than it increases awareness of common errors. I've started to keep a list of bugs that I find in my code, along with what could have led to them. The main question I have is this: What information related to my mistakes...
Hi, I am executing a diff command in perl. my @lines = `/usr/local/bin/diff -udr \"$expected_file\" \"$gen_file\"`; if ($? != 0) { print ERRFILE "Diff between $expected_file and $gen_file failed\n"; return $diff_err; } Here the diff might have failed because of some reason.

Is there any way to get a specific error condition when a C++ stream open fails? That is, whether it failed because the file didn't exist, or permissions were wrong, or etc. Basically I'm looking for functionality equivalent to errno for fopen() in plain C. GCC seems to set errno properly, but that doesn't seem to be required by the C++...
