C ++如何直接通过程序自动创建对象

Question

好的，我搜索了问题，但找不到答案，或者没有使用合适的术语。

if(choice == 2){
    string tempName, tempAddress; int tempNic,tempContact;
    cout << "\n\t\t*\tWelcome to Our Sponsor Registeration Section\t*\n\n";
    cout << "Please enter your name : "; cin>>tempName;
    cout << "Please enter your National Identity Card Number : "; cin>>tempNic;
    cout << "Please enter your Contact Number : "; cin>>tempContact;
    cout << "Please enter your Address : "; cin>>tempAddress;
    //  prototype Sponsor(string n, string add, int nic_n, int phone) constructor
    Sponsor (Constructor goes here) // how to make many objects now?
}

代码贴在这里https://codeshare.io/aVxl42

检查第 69 行，我将在其中使用构造函数添加值，这样我可以添加 1 个对象，但是如果正在使用程序的人想要添加更多对象，我应该怎么做呢？

我知道我需要封装 61 到 70 之间的东西。 请帮我解决这个问题。

我猜你想让它循环？我建议一个while循环。 我从来没有使用过向量（教授禁止它）所以我可能会犯一些错误，但你会明白整体观点。

bool stop = false; //This is to check after each loop if it should continue or not
char contChoice;
vector<Sponsor> sponsors;

while(!stop){
    if(choice == 2){
        string tempName, tempAddress; int tempNic,tempContact;
        cout << "\n\t\t*\tWelcome to Our Sponsor Registeration Section\t*\n\n";
        cout << "Please enter your name : "; cin>>tempName;
        cout << "Please enter your National Identity Card Number : "; cin>>tempNic;
        cout << "Please enter your Contact Number : "; cin>>tempContact;
        cout << "Please enter your Address : "; cin>>tempAddress;
        //  prototype Sponsor(string n, string add, int nic_n, int phone) constructor
        sponsors.push_back(Sponsor(tempName, tempAddress, tempContact, tempNic)); 
        //Add whatever other arguments you want to pass in, in whatever order
        cout << "Do you want to continue? [Y/N]: "; cin>>contChoice;
        if(contChoice == 'N' || contChoice == 'n') 
              stop = true;
        else stop = false; //This isn't really necessary since it is false by default
    }
}

但我也建议您至少在 Sponsor 中创建集合成员函数。您还可以使用动态数组并使其展开，这比向量更棘手，实际上更棘手。
