 | the reason is because your different functions individually parse each character without regard to what the other is doing. Specifically, your "SkipOverRestOfCommand" function disposes of the ';' character without properly accounting for it to the "SkipBlanks" function. in the even someone enters a ';' before any commands, your "SkipBlanks" function … |
| | you're trying to use a 20-year-old compiler on a modern OS. that's the problem.

| | this is the reason why globals are generally considered bad programming. unless you have a compelling reason to do so, do not use global variables. pass your array as a pointer argument into the functions that will be making use of it and/or modifying it. your problems will disappear.  |
| | scanf is often the source of input problems. as you can see, you have the most trivial example and it's [I]already[/I] being problematic. since there are better alternatives readily available, you'll do well to learn to stop using it as soon as possible. i too am partial to [URL="http://www.cplusplus.com/reference/clibrary/cstdio/fgets/"]fgets()[/URL]. it's … |

| | i've never heard of Relo as an IDE, so I don't know anything about it. If you're using it with the MinGW compiler, I suppose it should be fine. open up a new project and either write or copy and paste your C code. if it's anything like any other … |

| | i tend to avoid "do/while" loops.
