Couldn't find the code you mentioned.

Use std::string instead of plain C-style strings. If you declared temp
something as:

char temp[ SOME_LEN];

then temp == "n" will compare two pointers instead of two strings. The
result of comparing will be always false.

If you use std::string like:

std::string temp;

then the operator== is overloaded and it will compare the two strings.
