Start programming with C

As we talked before about programming with Java, I find out that we are going to use C this year. I wrote some programs using C before, but it is my first time on Ubuntu.
I tried to download some IDE's but the result was not really very good, I had a lot of problems in compiling or in using the IDE itself.
Fortunately, my friend Rania tell me that I do not have to do all that as Ubuntu has a C compiler and a C++ compiler and all I have to do to compile a C or C++ file is a simple command.
Let's see how
1 - Create an empty file in any directory.
2 - Name the file for example try.c or try.cpp
3- Open the file and write your code.
Compilation
4 - Open terminal and change the directory to the one containing the source file using the command cd
                                    cd directory path
5- To compile C file type the command
                                    gcc -o ./try.o ./try.c
    To compile C++ file
                                    g++ -o ./try.o ./try.cpp
6- To run the file type the command
                                    ./try.o

Good Luck
