使用Visual Studio C ++时发生400多个错误

Question

I am working on some coursework and the code works perfectly fine on the university system but when I transfer the exact same code to my own PC, I get over 400 error messages. These consist of:

• Cannot open source file "name.h"
• The global scope has no "name"
• identifier "name" is undefined
• explicit type is missing ('int' assumed)
• A full list is here https://pastebin.com/CRJd7hAp

I get these errors on all of my code, even something as simple as a Hello World program

#include <iostream>
using namespace std;
int main()
{
cout << "Hello world!  " << endl;
system("pause");
return 0;
}

I am at a loss as for what to do.

Answer 1

I reinstalled Visual Studio and set the SDK from 8.1 to the newest release. Everything is working fine now. Thank you
