Use of Proper Names for Identifiers

Concepts of Programming Methodology

Programming is basically solving a particular problem by giving coded instructions to the computer. Furthermore, the whole scenario of programming cycle involves writing, testing, troubleshooting, debugging, and maintaining a computer program. Moreover, a good program should have clarity and simplicity of expressions, should make use of proper names for identifiers, contain comments, and have proper indentation.

Programming Process Cycle

The steps of programming are as follows:

Writing

This step involves writing the desired output of the code. besides, drawing a flowchart depicting all the steps from beginning to end. Then the programmer writes the first copy of the code on the programming software.

Testing

This step is about testing the code against the test cases. If the output is according to desired test cases, the code is correct.

Troubleshooting

After testing the program we perform the error correction in this step.

Debugging

It is the process of finding the exact location of error in the code.

Running

After all these steps the program is run to get the desired output.

What is an efficient program?

A program that gives the correct desired output for every input, including the wrong input is an efficient program. Moreover, it should produce correct results in less time and use less memory space. Besides, an efficient program should have clarity and simplicity of expressions, should make use of proper names for identifiers, contain comments, and have proper indentation. Here, we will study about use of proper names for identifiers in detail.

Use of proper names for identifiers

An identifier is basically a name that identifies an object or an object of classes. Moreover, the name associated to any function, constant or variable refers to that particular object. There are certain rules to make use of proper names for identifiers. These are as follows:

• An identifier can include only capital letters, small letters, digits, and underscore .
• The name should be meaningful. For example, if you are storing name of a person declare the identifier as ‘name’.
• Use meaningful names for defined constants. For example ‘eular_constant=2.71’.
• Don’t use similar names more than once.
• Do not use single lettered identifiers such as ‘a’, ‘d’, etc.
• Keywords should not be used as identifiers.
• Refer to particular rules of each programming language.
