Iostream Library and Basic I/O in C++ - Conclusion
(Page 4 of 4 )
All of this looks good, but what if you want to read a whole line of data? As you can see, the stream extraction will delimit each input flow by thewhitespaces it will find. This obviously makes it impossible to read a whole line. However, there is another way to accomplish this, by using the "getline" function.
The result will be put into a string, though you need to include thestringheader and declare it. The function is also declared in this header in the form of a template, making it possible to work for both narrow or wide characters.
#include <string>
...
string putInTo;
getline( cin, putInTo, ' n');
I have explicitly requested to use as delimiter the newline character, just to show you that as the delimiter, you may use any character, but by default, it has defined the newline one. There you go; you've just learned the basics of how to communicate with users in C/C++.
All that is left is to start playing with the compiler, experimenting with different situations, and getting used to the method. Don't you find this more practical than the standard I/O used in C/C++?
