stdafx.h可能會否定iostream

Question

當我嘗試使用Visuale Studios（2017社區）進行構建時
我收到一個錯誤消息，告訴我包括“ stdafx.h”（代碼C1010）
當我這樣做時，我遇到幾個問題，告訴我我有琴弦
沒有定義，其他問題通常只會在我發生時發生
忘記iostream。 這是我使用過的唯一編譯器，但是在線編譯器似乎可以工作（ https : //onlinegdb.com，http://cpp.sh ）

#include <iostream>
#include <string>
using namespace std;
int main()
{
string var1;
std::string pass;
std::cout << "Enter Any word" << std::endl;
std::cin >> pass;
cout << "1.what is 9 x 9" << endl;
std::cin >> var1;
cout << "2.what is 9 x 8" << endl;
std::cin >> var1;
cout << "3.what is 19 x 2" << endl;
std::cin >> var1;
cout << "4.what is 27 x 10" << endl;
std::cin >> var1;
cout << "5.what is 87 x 90" << endl;
std::cin >> var1;
cout << "6.what is 989 + 10" << endl;
std::cin >> var1;
cout << "7.What languages can Putin speak" << endl;
std::cin >> var1;
cout << "8.what is the square of 100" << endl;
std::cin >> var1;
cout << "9.What is the first word in the family guy theme song" << endl;
std::cin >> var1;
cout << "What is the answer to #5" << endl;
std::cin >> var1;
cout << "What is the answer to #7" << endl;
std::cin >> var1;
cout << "What is the answer to #9" << endl;
std::cin >> var1;
cout << "what is 989 + 10" << endl;
std::cin >> var1;
cout << "what was your word?" << endl;
cin >> var1;
if (var1 == pass)
{
    cout << "correct";
}
else
{
    cout << "wrong, you stynk";
}
}

您可以通過轉到項目屬性-> C / C ++->預編譯頭，然后選擇不使用或創建來禁用預編譯頭 。

或者，包括"stdafx.h"並將其他包含移動到該文件。
