这段代码是什么意思?

#include <iostream>
using namespace std;
int main( )
{
char c[10];
c[0] = cin.get( );
cin.get( c[1] );
cin.get( &c[2],3 );
cin.get( &c[4], 4, '7' );

cout <<c<< endl;
}

The get Function
The unformatted get member function works like the >> operator with two exceptions. First, the get function includes white-space characters, whereas the extractor excludes white space when the ios::skipws flag is set (the default). Second, the get function is less likely to cause a tied output stream (cout, for example) to be flushed.

A variation of the get function specifies a buffer address and the maximum number of characters to read. This is useful for limiting the number of characters sent to a specific variable, as this example shows:

#include <iostream.h>

void main()
{
char line[25];
cout << " Type a line terminated by carriage return\n>";
cin.get( line, 25 );
cout << ' ' << line;
}

In this example, you can type up to 24 characters and a terminating character. Any remaining characters can be extracted later.

cin.get( &c[2],3 );
cin.get( &c[4], 4, '7' );
中cin.get的用法和cin.getline一样。
