Methods: The methods could be used to break a complex program into small pieces. The “void” method simply executes a statements group and then terminates. A value returning method would return a value to statement that has called it. While calling a method, program would branch to that method. It would then execute statements in its body. The values that are sent into a method are termed as “arguments”. A “parameter” denotes a special variable that holds a value that is being passed into a method. The “passed by value” means that only copy of a value of argument is been passed into parameter variable. A “local variable” is been declared inside a method, it is not accessible for statements outside method. A process in which a problem is been divided into smaller pieces is termed as “functional decomposition”. Example: Consider the example of method definition which is given below: Public static void method() { Statement; } Here, “statement” denotes the body of method, that is to be executed when “method()” is been called.

Program Plan Intro

Methods:

The methods could be used to break a complex program into small pieces.

The “void” method simply executes a statements group and then terminates.

A value returning method would return a value to statement that has called it.

While calling a method, program would branch to that method.

It would then execute statements in its body.

The values that are sent into a method are termed as “arguments”.

A “parameter” denotes a special variable that holds a value that is being passed into a method.

The “passed by value” means that only copy of a value of argument is been passed into parameter variable.

A “local variable” is been declared inside a method, it is not accessible for statements outside method.

A process in which a problem is been divided into smaller pieces is termed as “functional decomposition”.

Example:

Consider the example of method definition which is given below:

Public static void method()

{

Statement;

}

Here, “statement” denotes the body of method, that is to be executed when “method()” is been called.

Assume that a string of name & surname is saved in S. The alphabetical characters in S can be in lowercase and/or uppercase letters. Name and surname are assumed to be separated by a space character and the string ends with a full stop "." character. Write an assembly language program that will copy the name to NAME in lowercase and the surname to SNAME in uppercase letters. Assume that name and/or surname cannot exceed 20 characters. The program should be general and work with every possible string with name & surname. However, you can consider the data segment definition given below in your program. .DATA S DB 'Mahmoud Obaid." NAME DB 20 DUP(?) SNAME DB 20 DUP(?) Hint: Uppercase characters are ordered between 'A' (41H) and 'Z' (5AH) and lowercase characters are ordered between 'a' (61H) and 'z' (7AH) in the in the ASCII Code table. For lowercase letters, bit 5 (d5) of the ASCII code is 1 where for uppercase letters it is 0. For example, Letter 'h' Binary ASCII 01101000 68H 'H'…
