C++ - 简单的 hello world 在 vscode 中不起作用

Question

I've just started programming in c++ and I've a problem that is probably really simple but I've been trying to solve it for a long time. Cout prints all built-in variables but when I try to print a string variable, it doesn't work (it doesn't print anything even if there are other couts with other things to print that aren't strings).

In short, when there's a string variable in the code, nothing works , at least that is what I noticed.

That doesn't print anything

#include <iostream>
#include <string>
using namespace std;

int main() {
    string greeting="hello";
    cout << greeting;
    }

But that works:

    cout << "hello"; 

I've tried the same exact code in online editors and it does work.

EDIT 1:

In the computer's terminal, this is what is shown: procedure entry point is not found... in the dinamic link library...

Path: This is the mingw path: C:\Program Files (x86)\mingw-w64\i686-8.1.0-posix-dwarf-rt_v6-rev0\mingw32\bin

EDIT 2

Finally solved it. I've copied the libstdc++ and the libgcc to where I have the.exe.Thank you all for your support. Special thanks to @HolyBlackCat.

Answer 1

The solution to errors like "procedure entry point is not found" is:

• Make a list of all .dll s located in your compiler's bin directory.

• Go through C:\Windows and C:\Windows\System32 and make sure none of those dlls are there. If you find any, move them somewhere else (or delete them).

• Add your compiler's bin directory to the PATH , as the first entry.

Answer 2

I should see the whole code, but considering it doesn't work only with a string , probably you didn't use the namespace std : Try this:

#include <iostream>

using namespace std;

int main()
{
    string greeting = "Hello";

    cout << greeting;
}

If it doesn't work, show me the whole code and I'll see if I can help!
