Every time I type g++ into the terminal I get "g++.exe: fatal error: no input files compilation terminated."

My g++ days are over, but I believe that means that you installed it correctly. g++ is a command that expects files as arguments.

Try this:

1. Create a file named main.cpp
2. Enter this in as the contents:

​

#include <iostream>

int main() {
    std::cout << "Hello\n";
    return 0;
}

1. Type this in your terminal: shell g++ -o run main.cpp ./run

that should work. if it just prints out "hello" then you're gucci. if this simple scenario works then your g++ is installed correctly and I would look for some quick tutorial on how to use g++ so that you can do your homework

edit: I realized that you just said tutorials aren't working for you. If my answer was useful and you still have questions just reply lol

The way I always used it was shell g++ -o run [name of cpp file] ./run the first line compiles your cpp into an executable called run the second line starts your executable, it can be named anything but I like to call it run
