To compile and run programs on Linux you have first to login into your account in linux.uwsuper.edu with your login and password provided by the instructor.
gcc filename.c | for C programs |
g++ filename.cpp | for C++ programs |
If the compilation is successful you will see no warnings on the screen. Just a new prompt appears in the line following the compilation instruction. If the compiler finds an error, the number of the line in your source file containing the error will be displayed.
./a.out |
Alternatively, to create an executable file with a specific name, use the g++ instruction with the "-o" key:
gcc filename.c -o filename2 | for C programs |
g++ filename.cpp -o filename2 | for C++ programs |
In this case executable file filename2 will be created and can be executed by entering
./filename2 |
If your program hangs up type Ctrl-C to terminate it.
Unix as well as Windows is an operating system, and a number of very convenient text editors and window managers are designed for it. However, since we use just a remote access to Linux machine via ssh that is not designed to exchange graphical information from the Linux screen, we have to type in all the necessary commands.
