working of iostreams in VC++ 6

[maharjun]

i have just observed this wierd thing with visual c++
the following is my code.[please forgive my poor C++ standard. im using it only because im doing it 4 a school project and the examiner wont be bright enough to understand what iss not in the syllabus. this is sad but true state of affairs in india)

#include <iostream.h>
#include <string.h>

int main()
{
    char c[10];
    strcpy(c,"hello\n");
    cout<<c;
    cout<<"world";
    cin.get(c[0]);
    return 0;
}

the statement cout<<c; and cout<<"world;" doesnt really output just after it has been executed.instead all the action that is taken by these too lines of code is the buffering. I observe that the output it gets done only when cin.get(...) is being executed dunno why. seems very wierd to me. i think this is more due to lack of my understanding of working of the iostreams than an issue of VC++.

id be grateful if someone clarified the working of istream and ostream(in this case or in general)

and please tell me a way to empty(forcefully output) a buffer at will.

//note that i have made the above observations using VC++ debugger

Because cout is tied to cin. When you make an input request on cin, cout is automatically flushed.

There are a number of ways, but the two most common are:

cout<<endl; // Print a newline and flush
cout<<flush; // Just flush
