Thread: cin.getline() and getwidth help

1#
Why isn't this working? (if it cant work with string, how do I save spaces into strings?)
cin.getline(sMovie);

2# (need to know this tonight)
How does getwidth work? I cant find good documentation on google.

tnx

#1 cin.getline() works with c character arrays

Code:

char cMOvie[255];
cin.getline(cMovie,sizeof(cMovie));

if you use std::string object

Code:

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

#2: I never heard of getwidth(), but that doesn't mean it doesn't exist

To use it with strings

Code:

getline(cin,string_name);

cin can also be replaced with a file stream, ect.

That is actually a bug in VC6. They fixed it in .net but did not fix it in any of the service packs for VC6.
Get a different compiler

Specifically look a setw

*edit*
Btw though, you can fix the getline function your self:

That is a pretty well known bug in VC6, and I fixed it on my compiler, but as I remember it, it was very hard to figure out which file contained the line of code you are supposed to change: msdn didn't have clear instructions on that.

This is probably the solution to the problem.

That's the same link Enahs gave. Here's another one: http://www.dinkumware.com/vc_fixes.html

The file you need to modify is <string>.
