Damn C++ iostream

[tvjames]

Basically i need to use
std::getline(std::cin, reason)

reason is a std::string
and well i would have expected this to work perfectly except for the fact that the program does not wait for user input and just goes on to the next prompt in the program ... this is quite frustrating

yet it works as expected if used from main() ... but where i am using it from is deep inside a class.

Thanks

Have you tried cin.readline(reason) ?

I think you should also look at your class structure, its generally not good practice for something deep inside a class to be getting user input, it reduces the reusability of the code. Perhaps you should get the user input somewhere else and pass it as a parameter to the class that needs it.

You probably need to clear your input buffer cin.clear()? before attempting to read user input.

Thanks

BUT

i have tried as a function (not in class, local to the file) and that produces the same output, also
getline(cin, reason);
and
cin.getline(buff, buff_size);

(buff is a char[buff_size])
both cause the same problem in the class and also in a function ... yet if i put the same code in main it works fine

You need to flush the buffer for your class.

cin.ignore();


or consequently munch through each character till you get to the newline using cin.get()

but cin.ignore() should fix it.

*looks at people above him funny*

you should be using

std::string a;
std::getline(std::cin, a);

to ignore all characters upto and including the next '\n' on the input stream do

std::cin.ignore(std::numeric_limits<std::streamsize>::infinity(), '\n');

or, more readably, but not object oriented

while(cin.get() != '\n');
// or
cin.ignore(10000, '\n');

note: the above examples will *wait* for a \n if none exists on the stream.

feel free to post your code so we can look and debug/help

thanks everyone .. but the problem is solved .. and btw i didnt was to ignore the input .. i wanted to get it .. but thanks anyway

also as for the one 2 posts above, get also fails the only working one was read() .. but all fixed now

std::cin.sync()

fixed it all

thanks all
