The ability to detect non-fatal errors is a major distinction between PurifyPlus and similar programs from the usual debuggers.By contrast, debuggers generally only allow the programmer to quickly find the sources of fatal errors, such as a program crash due to dereferencing a null pointer, but do not help to detect the non-fatal memory errors.
Cppcheck is a static code analysis tool for the C and C++ programming languages. It is a versatile tool that can check non-standard code. [2] The creator and lead developer is Daniel Marjamäki. Cppcheck is free software under the GNU General Public License.
Lint is the computer science term for a static code analysis tool used to flag programming errors, bugs, stylistic errors and suspicious constructs. [1] The term originates from a Unix utility that examined C language source code. [2] A program which performs this function is also known as a "linter".
Finds all potential runtime errors and data races by abstract interpretation, can prove their absence, and can prove functional assertions; tailored towards safety-critical C/C++ code (e.g. avionics and automotive).

An additional step is a language-dependent algorithm for handling morphology. Even for a lightly inflected language like English, the spell checker will need to consider different forms of the same word, such as plurals, verbal forms, contractions, and possessives. For many other languages, such as those featuring agglutination and more complex ...
In the context of computer science, the C Bounded Model Checker (CBMC) is a bounded model checker for C programs. [1] It was the first such tool. [2] CBMC has participated in the Competition on Software Verification (SV-COMP) in the years 2014–2022. [3] It came in first in at least one category in 2014, 2015, and 2017.
In C++11, this technique is known as generalized constant expressions (constexpr). [2] C++14 relaxes the constraints on constexpr – allowing local declarations and use of conditionals and loops (the general restriction that all data required for the execution be available at compile-time remains).
Some programming languages allow a program to operate differently or even have a different control flow from the source code, as long as it exhibits the same user-visible side effects, if undefined behavior never happens during program execution. Undefined behavior is the name of a list of conditions that the program must not meet.
