A software bug is a bug in computer software . A computer program with many or serious bugs may be described as buggy. The effects of a software bug range from minor (such as a misspelled word in the user interface) to severe (such as frequent crashing ). Software bugs have been linked to disasters.

Automatic bug fixing. Automatic bug-fixing is the automatic repair of software bugs without the intervention of a human programmer. [1] [2] [3] It is also commonly referred to as automatic patch generation, automatic bug repair, or automatic program repair. [3] The typical goal of such techniques is to automatically generate correct patches to ...
Software development. In engineering, debugging is the process of finding the root cause of and workarounds and possible fixes for bugs . For software, debugging tactics can involve interactive debugging, control flow analysis, log file analysis, monitoring at the application or system level, memory dumps, and profiling.
Detection of unreachable code is a form of control flow analysis to find code that can never be reached in any possible program state. In some languages (e.g. Java [9]) some forms of unreachable code are explicitly disallowed. The optimization that removes unreachable code is known as dead code elimination .
Examples of debug code Print debugging. Print debugging is making use of print statements in order to find and isolate bugs in a program. It can be used to track the flow of data values of a piece of code. This type of debug code has some distinct disadvantages. It is temporary and usually removed when the bug is solved.
Cyclomatic complexity. Cyclomatic complexity is a software metric used to indicate the complexity of a program. It is a quantitative measure of the number of linearly independent paths through a program's source code. It was developed by Thomas J. McCabe, Sr. in 1976. Cyclomatic complexity is computed using the control-flow graph of the program ...
Uncontrolled format string is a type of code injection vulnerability discovered around 1989 that can be used in security exploits. [1] Originally thought harmless, format string exploits can be used to crash a program or to execute harmful code. The problem stems from the use of unchecked user input as the format string parameter in certain C ...
