#include <iostream>
using namespace std;
int main ()
{
    char ch = 'M';
    int i = ch;
   
    cout << "The ASCⅡ code for " << ch << " is "<< i << endl;
    cout << "Add one to the character code;"<< endl;
   
    ch = ch + 1;
    i = ch;
   
    cout << "The ASCⅡ code for " << ch << " is " << i << endl;
    cout << " Displaying char ch using cout.put(ch): ";
    cout.put(ch) << endl;  //而cout << cout.put(ch) << endl; 在输出N的同时也会输出ch的地址。
    cout << " Done !" << endl;
   
    return 0;
}

表示还是出现乱码呀，这个输出流中没有。。。。

好吧，表示刚看到你这个回复。懂了，原来那个“乱码”是地址，谢谢~~
