[英]How to access the struct attributes inside an STL Stack C++?
這是我的代碼
struct vidstruct {
int Video_ID; // -> Increment
string movietitle = "";
string genre = "";
string prod = "";
int numberOfCopies;
string MovImg_name;
};
struct customerstruct {
int Customer_ID;
string name;
string adress;
stack <vidstruct> cstack; // -> I want to access this one
// here is my declaration of methods
public:
VideoClass();
void returnVideo(vidstruct info,int sc); // ---
這是我正在嘗試訪問它的方法:
void VideoClass::returnVideo(vidstruct info,int sc) {
int top;
list<customerstruct>::iterator iter;
for (iter = myListCustomer.begin(); iter != myListCustomer.end(); iter++) {
if (sc == iter->Customer_ID) {
cout << iter->Customer_ID << " " << endl;
cout << iter->name << " " << endl;
cout << iter->adress << " " << endl;
cout << "Videos Rented: " << endl;
while (!iter->cstack.empty()) {
iter->cstack.top();
cout << info.Video_ID << " " << info.movietitle; // This is what I'm trying to do but it just gives me a random output.
iter->cstack.pop();
}
我想訪問 vidstruct 結構的 Video_ID 和 movietitle 屬性,但我真的不知道該怎么做。
在這里您可以找到一個完整的(但最少的)示例,它將演示您正在尋找的內容(也許)。 我試圖讓事情盡可能接近你的例子。

請(請:!): go 並了解stack
和list
的工作方式(以及何時應該使用另一個), struct
和class
之間有什么區別,僅提及我認為可以改進的很少的事情。
