3oranges 0 9 0 this looks for numbers returns the index inside the string where the first match is found otherwise it returns nil.
The operator returns a new string which now is ada.
Many of ruby s built in classes such as string range and regexp provide their own implementations of the operator also known as case equality triple equals or threequals.
Matching operator what is this funny looking ruby operator with a tilde.
Typically methods with names ending in modify their receiver while those without a return a new.
It allows you to do a quick index search using a regular expression.
After the we specify arguments.
Ruby format string examples use the format string syntax.
In this case a b c creates a new string.
Because it s implemented differently in each class it will behave differently depending on the type of object it was called on.

These intermediate objects are immediately discarded because they re not used any more.
Because of aliasing issues users of strings should be aware of the methods that modify the contents of a string object.
Now this string is passed to the method on hello which again creates a new string hello ada.
And b 13.

String objects may be created using new or as literals.
And google will answer this faster than even so ever could.
The execution get little slow when operator is used because the resultant string is stored in the new memory of the string object storing it.
Bitwise operator works on bits and performs bit by bit operation.
In ruby we apply the string format syntax the operator to ease this creation of formatted string data.

It s the matching operator.
Concatenation looks like this.
So string concatenation creates 2 more string objects even in our simple example.
We use the percentage sign to specify a format code within.
Add a comment.
A string object holds and manipulates an arbitrary sequence of bytes typically representing characters.
In the case of string object you can add two strings with the help of operator in ruby.
A nice to meet you b c do you like blueberries a b c nice to meet you do you like blueberries you can use the operator to append a string to another.
Assume if a 60.
The plus operator is generally used to add two integers but it is overridden in the case of string objects.
