increment in ruby

To increment a variable in Ruby, you can use the += operator. This operator adds a value to the variable and assigns the result back to the variable. Here is an example:

counter = 0
counter += 1

In this example, counter is initially set to 0. The += operator adds 1 to the value of counter, resulting in a new value of 1. The new value is then assigned back to the counter variable.

You can also increment a variable by any other value, not just 1. For example:

counter = 0
counter += 5

In this case, counter is incremented by 5, resulting in a new value of 5.

The += operator is a shorthand way of writing counter = counter + 1 or counter = counter + 5, depending on the value you want to increment by. It is a convenient way to update the value of a variable without having to write the variable name twice.

I hope this explanation helps you understand how to increment variables in Ruby using the += operator. If you have any further questions, feel free to ask!
