I’m trying to code in C++, but when I need to compile and execute, I need to return a line. To return, as far as I know, you press enter, but enter only causes the program to execute my unfinished code. This isn’t a big deal, its just a minor annoyance.
I’m struggling to understand what you’re doing, tbh.
If you’re working through the Codecademy C++ material, “compile” and “execute” are two different actions in the learning environment. You compile with
g++ my_code.cpp and execute it with
./a.out for example.
These would already be two separate commands* to the terminal, so it would (assuming no errors) look like:
$ g++ my_code.cpp $ ./a.out some output from your code is here! $
If that’s not what you’re talking about, then I’m genuinely confused. Unless you can elaborate a bit more about what you’re doing and how, with a screenshot maybe, I’m lost.
* Unless you’re familiar enough with bash to know you could do
$ g++ my_code.cpp; ./a.out for the same result.
Sorry for not being clear enough, I know what the commands are, and how execute and compile work, it’s just that I need to go down a line in the bash terminal and I don’t know how.
Go down? Start a new line? Should the program do that, or you?
When does a terminal display a new line? It’s not an action to be carried out, it’s a character in the output stream, so if your program should terminate a line, then it would need to write a line termination character.
Might make more sense if you don’t think of your program as having control over your terminal, instead it simply writes characters that you can direct into a file or into a terminal application or a network connection or be ignored altogether.
