如何在c+中创建、访问和利用字符串数组+； 我是C++的新手，我想知道如何创建空数组字符串数组， 到目前为止，我有： #include <iostream> #include <iomanip> using namespace std; int main() { int numOfStudent; char again; do { cout << "How many students are in the class?"; cin >> numOfStudent; while (numOfStudent > 30 || numOfStudent < 5) { cout << "The number of students must be in the range 5 - 30\n"; cout << "How many students are in the class?"; cin >> numOfStudent; } for (int count = 1; count <= numOfStudent; count++) cout << "Enter the full name of student " << count << endl; cin >> // this is the part where i want to use an array to store cout << "Here is the list of students you have entered:\n"; for (int x = 1; x <= numOfStudent; x++) cout << x << ". " // and this is the part where i want to read an array and print out cout << "\nDo you want to continue (y/n)?"; cin >> again; } while (again == 'Y' || again == 'y'); } #包括 #包括 使用名称空间std； int main（） { 国际学生； 再次烧焦； 做 { cout>numof学生； 而（numOfStudent>30 | | numOfStudentnumof学生； 而（numOfStudent>30 | | numOfStudentnumof学生； 而（numOfStudent>30 | | numOfStudent

来说，这似乎是一个家庭作业问题，但即使是这样，它也是如此基本，代码答案应该有助于让您跳转到更复杂的主题：

#include <iostream>
#include <iomanip>
#include <vector>
#include <string>

using namespace std;

int main()
{
    int numOfStudent;
    char again;

    vector<string> students;

    do
    {
        cout << "How many students are in the class?";
        cin >> numOfStudent;
        while (numOfStudent > 30 || numOfStudent < 5)
        {
            cout << "The number of students must be in the range 5 - 30\n";
            cout << "How many students are in the class?";
            cin >> numOfStudent;
        }


        for (int count = 1; count <= numOfStudent; count++)
        {
            string name;
            cout << "Enter the full name of student " << count << endl;
            cin >> name; // this is the part where i want to use an array to store
            students.push_back(name);
        }

            cout << "Here is the list of students you have entered:\n";
        for (int x = 1; x <= numOfStudent; x++)
            cout << "Student #"<<x << " is  "<<students.at(x-1)<<"."<<endl; // and this is the part where i want to read an array and print out


            cout << "\nDo you want to continue (y/n)?";
        cin >> again;
    } while (again == 'Y' || again == 'y');

}
