What is software debugging? Debug is a term in programming and refers to a multi-step process involving identifying a problem, isolating its source, correcting it, or discovering a way around it. The last debugging stage (Debugging) also includes testing the patch or approved solution to ensure it works.
Debugging begins with detecting errors in code, whether syntactic, logical, or otherwise, and then replacing or rewriting them correctly by the developer. Debugging is part of the software testing process and integral to the entire software development life cycle.

What is debugging?

The terms debug for software bugs and debug for debugging are attributed to Admiral Grace Hopper, a progrnaturalneer known for her wit. When a natural bug (an insect) got stuck between electrical relays and caused problems in the US Navy’s first computers, Admiral Hopper’s laptops team removed the bug from the laptop, and the moth that had Today was saved in the Smithsonian.

Types of errors

In general, it can be said that there are three types of errors in programming:

• Syntax
• Semantics
• Logical errors

Syntax

Syntax means correctly placing expressions and formulas in the programming language; Syntax specifies the most accurate way to place statements to have an error-free program. Of course, it is better to know that programming languages have their own syntax rules. Whenever you encounter a Syntax error, know that the rules and the way the expressions are placed are wrong, and you should correct it.

Example:

Neda eats an apple is a correct expression, but when we say Neda eats an apple, this expression is incorrect; in semantics, errors here are spelling mistakes.
Semantics

Semantic errors are the meaning and correct results of expressions following each other. You write all the codes without any right and encounter a semantic error, meaning the proper meaning of these codes has not been received.

Example:

Neda is Sa urgeon,.In this example, all the punctuation marks and the location of the verb and subject are correct, but the incorrect sentence is incomprehensible.
Logical errors

Recognizing logical errors is not understand eryone’slogical itfallacies—logifallaciesiesmer to identify his logical fallacies. Logical fallacies are challenging to detect and require much time and expertise.
Example:
We know that 2 times two equals 4, but in programming, we are faced with a number other than 4; this is when we encounter a logical error.

What are the most critical debugging strategies?

Source Code Analyzers are one of the most important debugging tools. It includes useful features such as vulnerability detection, joint code error detection, and complexity analysis that finds, analyzes, and tests complex modules that are difficult to understand.

There are many other strategies, including:

Static Analysis Strategy: The developer examines the code without executing the program.
Typo correction strategy: Also known as tracking. The developer places typing instructions in different parts of the code to follow the flow of the program.
Remote Debugging Strategy: The debugging tool that the developer uses runs on a different system from the software development system.
The importance of debugging

Why do we need debugging in programming? As mentioned, debugging is an essential code management and software development tort. Debugging gives software engineers and developers the ability to fix bugs before release. Debugging can increase the quality of the product and leave a positive impression on it.
Debugging process

In the first step, it is necessary to identify the error or bug well. This step may seem time-consuming or tedious because, besides placing the mistake, you must also find the location x bugneand t step; you should analyze the identified error, finally fix the bug, and perform tests to ensure. Be sure to note that doing the test and final testing will significantly improve your work.
