What is the coding standard?
Coding standards are a set of principles and recommendations that assist developers in producing less erroneous and more understandable, efficient code. They also provide developers with a standardized approach to writing really useful code.

They are specific guidelines that define the programming style, protocols, and techniques used in your code. They must be clearly described, made available to developers, and ensure that they adhere to predetermined rules. This in turn guarantees that all developers can comprehend, debug, and maintain the code, regardless of level of experience.

Why coding standards are important ?
Coding standards support the production of high-caliber software and code.

The users may be sure that your software is dependable, safe, and secure when it has high-quality code.

Enhance Code Quality: Consistent, readable, and maintainable code is the way of coding standards. As a result, developers can comprehend and work with the code more easily, producing software of a higher caliber.

Boost Efficiency: By avoiding frequent errors , developers can save time by adhering to code standards.

Encourage Collaboration: It gives developers a common language to work , enabling them to share code and communicate efficiently.

Verify Compatibility: This verifies that the code works on various operating systems, browsers, and device combinations.

Lower Maintenance Costs: Developers can prevent the introduction of new issues and perform code modifications more quickly and easily by adhering to established standards.

Below are a few of the coding guidelines:
Limit the globals usage.
Standard headers for different modules.
Naming guidelines for functions, constants, global variables, and local variables.
Indentation.
Exception handlings and Error returns.
Avoid using a coding style that is too complex to comprehend.
Avoid using an identifier for multiple purposes.
Code should be well documented.
Length of functions should not be very large.
Avoid using GOTO statement.
