how do i access my command line?

[seungyeon]

i opened CMD
and i typed something in and nothing happens

[gunnerfunner]

you're on Windows I suppose. type

g++ --version 

to see that the compiler is installed correctly

[seungyeon]

g++ is not recognized

im using dev c++

[seungyeon]

mingw compiler and tdm gcc

[Enoizat]

Have you checked your path?

[Thomas1965]

Why do you bother about the command line if you use Dev C++ ?
The MinGw compiler is inside the Dev C++ folder, probably in MinGW64/bin but that depends on your system.

[jonnin]

what exactly did you type that did not do anything? It should at least say
"bad command or file name" or something along those lines.
Doing nothing at all seems wrong.

probably didn't press <Return>
and turned off echo
