Comparison operators take simple values numbers or strings as arguments and used to check for equality between two values.
String equal ruby.
B is interpreted as a plus b where the plus.
Because it s implemented differently in each class it will behave differently depending on the type of object it was called on.
The simplest string literals are enclosed in single quotes the apostrophe character.
We define an empty string as a string of zero length.
For the rare case when you actually need to check if two objects are the same object there s the method equal.
E g a equal a returns false.
There is a corresponding form of abbreviated assignment operator.
Here str and other str are the strings.
For each operator plus.
For example a plus.
In practice this is almost always what you want.
While evaluating the expression a a ruby will actually create two different string objects which both contain a single character a.
Notice that we use two equal symbols to mean equality.
True or false basis on the equality.
Comparison returns 1 0 1 or nil depending on whether string is less than equal to or greater than other string.
How to check if a string is empty.
Method in the object referred to by variable a is called with b as its argument.
Ruby size 4 you can also use length instead of size they do the same thing.
How to get the string length.
Nil is returned if the two values are incomparable.
A string object in ruby holds and manipulates an arbitrary sequence of one or more bytes typically representing characters that represent human language.
One equals sign in ruby means assignment make sure to use when you want to find out if two things are the same.
Ruby supports a rich set of operators as you d expect from a modern language.
Ruby provides following comparison operators.
Is a string class method in ruby which is used to check whether the strings are equal or not if they have the same length and content.
If the strings are of different lengths and the strings are equal when compared up to the shortest length then the longer string is considered greater than the shorter one.
Most operators are actually method calls.
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.
The text within the quote marks is the value of the string this is a simple ruby string literal.
With an if statement you can check if something is true.
True if x is exactly equal to y not equal.
