C++中字符串变量的运算

C++中字符串变量的运算

 

// C++中字符串变量的运算
#include<iostream>
#include<string>
using namespace std;
int main()
{
    string word1 = "I Love " ;
    string word2 = "my mon" ;
    string word;

    // 可以直接使用" + "
    word = word1 + word2 ;
    cout << word << endl ;

    // 可以直接使用" = "
    word1 = word2 ;
    cout << word1 << endl ;

    // 可以直接用" == " 或" != "比较
    if ( word1 == word2 )
        cout << "word1 == word2" << endl ;
    else
        if ( word1 != word2 )
        cout << "word1 != word2" << endl ;

    // 可以直接用" > "或" < "
    if ( word1 > word2 )
        cout << "word1 > word2" ;
    else
        cout << "word1 < word2" ;

    return 0;
}

结果
