Console Application doesn't work correctly
l4nd3r:
I'm having trouble with this encrypt-decrypt program, it compiles but it isn't saving(writing) nor reading the words on the .txt file, but the weird thing is this same code is working on Visual Studio, but as my teacher requires the use of Code::Blocks I'm here asking for help to discover why it isn't working on Code::Blocks.
Also, as I'm Brazilian, so some of the words of the code is in Portuguese, I'll try to give a all around idea of what each function does.

If anyone has doubt any about a meaning of a word, just ask. Thanks.

Edit: Just realized a CB Related problem that might cause the issue.
Post the Full Build Log here and the run commands and your file locations.
Edit2: You likely are failing to open the file; you need to always check the file was opened.
I would suggest learning what Compiler your instructor is using; Note, Code::Blocks is NOT a compiler!

The compiler we use is the 'default' GNU GCC Compiler, but he never mentioned this is the one we should use. He just requires the use of Code::Blocks IDE.
And what does CB mean?

CB or C::B both means Code::Blocks.
You need to follow these steps if you want me to help you.
1. Do a Clean
2. Do a Build
Post that full build log (Looks like you likely already did this part; but, I am NOT sure that you did).
3. Do a Run.
Post the run command.
If you do NOT know how to do one of the steps, ask!
Tim S.
PS: Your instructor may be a Idiot since he did NOT tell the Compiler to use under Code::Blocks.
