it Compare the variable a and the variable b are same.
The value of b is assigned to variable a but if b changes later, it will not effect the value of variable a.
The value of b is assigned to variable a but if b changes later, it will effect the value of variable a.
The value of variable a is assigned to variable b, and the value of variable b is assigned to variable a.
