对string 简单应用

#include<iostream>#include<iomanip>#include<string>using namespace std;int main(int argc, char** argv) {    string str = "高德纳 美国 计算机科学家 计算机程序设计艺术";    string str_temp = " ";    str_temp.assign(str);// 字符串复制    string result[4] = { " "," " ," "," " };    int position = 0;    for (int i = 0; i < 3; i++)    {        position = str_temp.find(" ");//第一次出现的位置        result[i] = str_temp.substr(0, position);// 取出字符串从0 开始 position 个字符        str_temp = str_temp.substr(position + 1, str_temp.length() - position); // 删除上述字符    }    result[3] = str_temp;    cout << "姓名： " << setw(8) << result[0] << endl;    cout << "国籍： " << setw(6) << result[1] << endl;    cout << "职业:" << setw(14) << result[2] << endl;    cout << "代表作 ： " << setw(18) << result[3] << endl;    str_temp.swap(result[0]);    // 将本字符串与result 进行交换    for (int j = 1; j < 4; j++)    {        str_temp += " ";        str_temp.append(result[j]);  //  还原操作  将result 追加到本字符串末尾    }    int equal = str.compare(str_temp);  // 将两个字符串进行比较  相同  结果为零    if (equal == 0)    {        cout << "Success Matching!" << endl;    }    else        cout << "Unsuccessful Matching!" << endl;    return 0;}
