what does "it doesn't work" mean?

Do you get compiler errors? If so tell us what they are.

Does it compile but doesn't behave as expected? If so explain desired behavior and the behavior you're actually getting.

Does it crash? If so describe exactly what happens, how far in the program you get, and to the best of your understanding what is making it crash (when you provide certain input -- or always just after startup).

Just saying "this doesn't work" and pasting a huge chunk of code (which isn't even in [code] [/code] tags) makes us have to do a lot of unnecessary work to try and help you. I for one tend to not bother with posts like these (no matter how urgently you claim to need the info) but felt like chiming in with a post like this because I've been seeing a lot of these kinds of posts here lately.

I have been getting this error on the compiler and the same error comes up ten times for my "cins"

error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'std::string' (or there is no acceptable conversion)

Im sorry for the lack of info and im grateful you are trying to help :)

[Disch]

I searched the whole source and I didn't see you use << with 'cin' anywhere, so I'm guessing you're misinterpretting the error.

please edit your original post and put the code in code tags:

[code]
.. put your code here ..
[/code]

Then please tell me what line(s) the errors are occuring on.

PS - just tried compiling in GCC and it works fine (I'm guessing 'DEV' also uses GCC -- which is why it works there as well). I don't have MSVS to test with, so unfortunately I can't see the errors for myself.

try to #include <string>

[HSABRAHAM]

error C2679: binary '>>' : no operator defined which takes a right-hand operand of type 'class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >' (or there is no acceptable conversion)

I get this error on line 40, 63, 64 , 65, 66, 67,68,69


and then I get this on line 80
rror C2677: binary '!=' : no global operator defined which takes type 'class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >' (or there is no acceptable conversi

hey bazzy thanks, now i only have two errors


H:\Private\My Documents\PROJECT 5 COMPLETE.cpp(80) : error C2677: binary '!=' : no global operator defined which takes type 'class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >' (or there is no acceptable conversi
on)


H:\Private\My Documents\PROJECT 5 COMPLETE.cpp(80) : fatal error C1903: unable to recover from previous error(s); stopping compilation
Error executing cl.exe.



Someone please help :)

[Bazzy]

in while (searchname!=List[i].lastName); you are comparing a string with a bool
