C++中cout输出字符串和字符串型指针地址值的方法以及C语言中的printf用法比较

#include <iostream>
using namespace std;
#include <stdio.h>
int main()
{
    char *pstr = "china";
    char *qstr = "america";
    char *q = "adf";
    char * s;
    s = "hello";

    printf("pstr = %p\n", pstr);  /*输出为字符串起始地址值*/
    /*由于C++标准库中I / O类对 << 操作符重载，因此在遇到字符型指针时会将其当作字符串名来处理，输出指针所指的字符串。

    cout << "pstr = " << pstr << endl;  /*输出为字符串*/
    printf("pstr = %s\n", pstr);  /*输出为字符串*/
    
    cout << "qstr = " << qstr << endl;
    cout << "q = " << q << endl;
    cout << "s = " << s << endl;
    printf("s = %p\n", s);
    return 0;
