Ruby program to demonstrate the string interpolation

Program/Source Code:

The source code to demonstrate the string interpolation is given below. The given program is compiled and executed successfully.

# Ruby program to demonstrate the 
# string interpolation

Str = "India";

puts "Hello #{Str}";
puts "Total is: #{5+2}";

Output:

Hello India
Total is: 7

Explanation:

In the above program, we created a string variable Str that is initialized with "India". Then we used string interpolation. Ruby calls the to_s() method on the string interpolation block, this tells the object to convert itself into a string.
