c++程序—字符串

1. C风格字符串：char 变量名[ ]="字符串值 "

int main()
{
    
    char str[] = "hello world!";
    cout << str << endl;


    system("pause");
    return 0;

}

　　2.　C++风格的字符串：string 变量名 = “字符串值”

• NB：要加一个头文件：

  #include<string>

#include<iostream>
using namespace std;
#include<string>

int main()
{
    
    string str = "hello world!";
    cout << str << endl;
    system("pause");
    return 0;

}
