我正在嘗試製作一個程序,它接收來自用戶的數字,然後重新排列從最小到最大的數字。我正在使用矢量(我剛剛瞭解到),它給我一個下標超出範圍的錯誤。我無法找到什麼代碼的一部分給了我這個錯誤,所以希望有人對矢量和C博學++可以找到它:C++矢量下標超出範圍錯誤1221

cout << "\nEnter a number or type 'x' to order:" << endl;
string reply;
getline(cin, reply);
if (reply != "x") {
int a = atoi(reply.c_str());
num.push_back(a);
cout << "\nYou currently have " << num.size() << " numbers added." << endl;
