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;
