I don't understand this.

It didn't find it anywhere I even decided to put it in in the D:\> but it keeps saying there is no such file directory.

Could you post the exact text of the error message. If using a cmd window, you can select and copy the entire contents by the key sequence:

ALT-SPACE    E    S    ENTER

ALT-SPACE

(menu should appear)

E

(choose Edit)

S

(select all text)

ENTER

(copy to clipboard)

Here

g++: error: HelloWorld.cpp: No such file or directory

[gunnerfunner]

We know from this error message that your compiler is actually working! Try changing the file name (but always with the .cpp extension) and/or location and if you have access to any other laptop or PC give it a shot from there as well but I don't see why it shouldn't work under current setup.

No such file or directory

We presume that you have created a file, written code into it, and saved it with name "HelloWorld.cpp".

What is the name of the file (if not HelloWorld.cpp)?

In which folder did you save the file to?

[StrawBerry Lips]

It is only called main.

[Peter87]

If your source file is called main without a file extension you need to explicitly tell the compiler that it is C++ using the -x option.

g++ -o HelloWorld -x c++ main

If your source file is called main.cpp the compiler will automatically assume it is C++ based on the file extension.

g++ -o HelloWorld main.cpp

If you want the executable file to have a different name you can substitute HelloWorld with whatever you want.

write like this one

g++ -o HelloWorld.cpp HelloWorld

./HelloWorld
