Statement 1 is incorrect. A relative reference changes when a formula is copied to another cell while Absolute references remain constant. However, it is safe to say that an absolute address can be preceded by a $ sign before both the row and the column values. It is designated by the addition of a dollar sign either before the column reference, the row reference, or both. Statement C is also correct. A mixed reference is a combination of relative and absolute reference and the formula (= A1 + $B$2) is an example of a mixed cell reference.
<em>1)</em><em> A relative reference will retain its references when copied to another cell.</em>
<em>2) An absolute address has a $ sign before both the row and the column values.</em>
<em>3) </em><em>= A1 + $B$2 is an example of a mixed cell reference.</em>
<em>4) </em><em>The address 7B is invalid.</em>
Explanation:
<em>We know that a call by reference method can be defined as a method of providing different arguments to a function and then that function copies the address of an argument into the formal pattern.</em>
A local variable is a variable which is declared within a method or is an argument passed to a method, it scope is usually local (i.e. it is hidden from other method). it can also have the same name as a local variable in another method and it loses the values stored in them between calls to the method in which the variable is declared. So all the option listed above are correct.
An accessor method is also an instance function that receives or establishes the value of an object's properties. This method is called methods through obtaining information about an entity. This method reverses it to process, which has two accessory string techniques to reach source string data reference length Accessor method.
