RubyonRails is similar to most programming languages where in one can use the command line in windows or a terminal in Unix based systems. All programs should be written and saves in plain text format for the compiler and interpreter to process it easily. The first program would give you a feel for the overall syntax of how the program is created and what the compiler does. Type the following code into the text file to see how it is done:
#this is a sample program
a = “This is”
b = “my first Ruby Program”
print “The concatenated line is :”
print a << b
The next post would show the continuation of the exercise.
