Question

C++编译异常？

#include<iostream>
#include<string>
using namespace std;
struct car { string name; int year; };
int main() {
cout << "How many cars do you wish to catalog?";
int a;
cin >> a;
cin.get();
car* A = new car[a];
for (int i = 0; i <= a; i++) {
cout << "Car #" << i + 1 << ":" << endl;
cout << "Pleaseenter the make:";
getline(cin, A[a].name);
cout << "Please enter the year made:";
cin >> A[a].year;
cin.get();
};
cout << "Here is your collection:" << endl;
for(int j=0;j<=a;j++)
cout << A[j].year << " " << A[j].name << endl;
delete[] A;
return 0;
}

测试的时候输入第一个INT值a之后就提示：
发了异常: 写入访问权限冲突。
_Left 是 0x51EE1DC。

这个该怎么解决，是我的语句有问题么？

Answer 1

for (int i = 0; i <= a; i++) //这里改为i<a

{      

cout << "Car #" << i + 1 << ":" << endl;

cout << "Pleaseenter the make:";

getline(cin, A[a].name);      //这里改为 A[i].name

cout << "Please enter the year made:";

cin >> A[a].year;    //这里改为A[i].year

cin.get();

};          //这个分号没用

cout << "Here is your collection:" << endl;

for(int j=0;j<=a;j++)              //这里改为j<a

cout << A[j].year << " " << A[j].name << endl;

delete[] A;

return 0;
}
