沒有實例參數列表

Question

匹配出於某種原因，一個字符不能在strcopy_s去（）; ...

#include <iostream> 
#include <cstring> 

using namespace std; 

struct DATE { 
    int year; 
    int month; 
    int date; 
}; 
struct Book { 
    char name[50]; 
    char author[50]; 
    int id; 
    DATE date; 
}; 

int main() { 
    Book book1; 
    DATE date1; 
    char bookName, bookAuthor; 
    int date, year, month; 

    cout << "Date Of Publishing? " << endl; 
    cin >> date; 
    cout << "Month Of Publishing?" << endl; 
    cin >> month; 
    cout << "Year Of Publishing?" << endl; 
    cin >> year; 
    date1.year = year; 
    date1.month = month; 
    date1.date = date; 

    cout << "Book Name ? " << endl; 
    cin >> bookName; 
    cout << "Book Author" << endl; 
    cin >> bookAuthor; 
    strcpy_s(book1.name, bookName); 
    strcpy_s(book1.author, bookAuthor); 
    return 0; 
}

Answer 1

正確。 strcpy及其家族取char*，而不是char。他們使用C字符串。無論如何，你通常無法將bookName放入單個字符中。

這就是說，歡迎來到21世紀。我們現在使用std::string，要容易得多。
