有人可以解释我如何循环文本，直到输入EOF字符？还有如何使用向量？

Posted 2023-01-19

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

//void FillNames(vector<string> & vecNames);

//void SortNames(vector<string> & vecNames);

int main() 
    string firstName;
    int i = 0;


    cout << "Information:" << endl;
    cout << "EOF character in windows is Control + Z" << endl;
    cout << "and EOF character on Mac is Control + D:" << endl;
    cout << "-----------------------------------------------" << endl;

    while (i < 13) 
        cout << "Enter first name only in all caps (example: JOHN)" << endl;
        cout << "Enter EOF character to exit name entry: ";
        cin >> firstName;
        i++;

答案

输入EOF后，您可以使用流的输入状态来中断循环：

while (i < 13) 
    cout << "Enter first name only in all caps (example: JOHN)" << endl;
    cout << "Enter EOF character to exit name entry: ";
    if (cin >> firstName)
        i++;
    else
        break;
