回答1:

I'd hazard a guess you're missing '}' in first else block.

To avoid such problems in the future, fix your indentation (or let AStyle or similar program fix it for you) and use editor that highlights the syntax (especially blocks of code between braces).

回答2:

Your first if else statement has a missing } after the { for your else. My suggestion: get rid of the { since it's only a single line of code.

回答3:

It could be that you miss "}" in the end, another important thing that you should beware is that try to use the full address of your files. I met the same problem, and different compiler would read adresses in different ways. So try to make clear the address of files.
