How to compile and excecute the code

1. Write the code in a text editor any other IDEs. Make sure to save the file and the extension must end with ".f90".

2. Double click mingw-w64 > Black screen will pop out > type gfortran test.f90 (note that test.f90 is a sample file name)

3. This will compile the program u wrote and create a.exe file into the folder we have created earlier (same path) but don't close the mingw-w64.bat window.

4. In the next line , type a.exe

5. The code will be displayed on the console(mingw-w64.bat)

6. Another way to compile is shown below.

   gfortran test.f90 -o test  
                     |    ^-------|
                <output>          |
                  <executed filename>
