一本很好的C++学习的丛书！初学者必看的

// write.cpp -- using cout.write()
#include <iostream>
#include <cstring>  // or else string.h

int main()

    using std::cout;
    using std::endl;
    const char * state1 = "Florida";
    const char * state2 = "Kansas";
    const char * state3 = "Euphoria";
	int len = std::strlen(state2);
    cout << "Increasing loop index:\n";
    int i;
    for (i = 1; i <= len; i++)
    {
        cout.write(state2,i);
        cout << endl;
    }

// concatenate output
    cout << "Decreasing loop index:\n";
    for (i = len; i > 0; i--)
        cout.write(state2,i) << endl;

// exceed string length
    cout << "Exceeding string length:\n";
    cout.write(state2, len + 5) << endl;

    return 0;
