Code Inspections in C++

In C++, ReSharper 2017.2 provides two kinds of code inspections: 188 inspections that detect errors such as broken syntax, unresolved symbols, compiler errors, etc. (you cannot configure or disable any of these inspections), and 124 proprietary code inspections, any of which you can disable or change its severity level.
These code inspections help you detect code issues in design time in all open files, and additionally they allow you to find code issues in specific scope.

Configurable C++ inspections are listed below, grouped in the following categories:

Common Practices and Code Improvements (13 inspections)

This category groups inspections that hunt for medium severity issues that mainly affect code readability.
InspectionDefault Severity
Compile-time constant expression can be replaced with either 'true' or 'false' Suggestion
Constructor of smart pointer used instead of its make function Suggestion
C-style cast used instead of a C++ cast Suggestion
Function returns by const value Suggestion
Member function may be 'const' Suggestion
Member function may be 'static' Suggestion
Non-explicit conversion operator Hint
Non-explicit converting constructor Hint
Order of member initializers does not match the initialization order Suggestion
Overriding function without 'override' specifier Suggestion
Result of a postfix operator is discarded Suggestion
Throw expression can be replaced with a rethrow expression Warning
Zero constant can be replaced with nullptr Suggestion

Compiler Warnings (9 inspections)

Inspections in this section detect compiler warnings before you compile.
InspectionDefault Severity
Default initialization of a const-qualified object of a type without a user-provided default constructor Warning
Explicit specialization in non-namespace scope Warning
Redeclaration of a template parameter from an outer scope Warning
Reference class member with 'mutable' specifier Warning
Static assertion failure Error
Unexpected syntax element Warning
Uninitialized dependent base class Warning
Union member of reference type Warning
Use of an incomplete type inside a template Warning

Constraints Violations (1 inspection)

This category includes code inspections, mostly with the warning severity level, which detect violations related to symbol attributes, including ReSharper's code annotations, and other similar issues.
InspectionDefault Severity
Inconsistent Naming Hint

Potential Code Quality Issues (77 inspections)

This category includes inspections that detect critical issues (code smells), mostly with Error or Warning level. This category also includes inspections that ensure localization assistance.

Missing include guard Warning
Mixed serial and positional arguments for boost::format Error
More than one implicit conversion applied during copy-initialization. This is non-standard Microsoft C++ extension Warning

Too many arguments in a call to boost::format Warning
Too many arguments in a call to printf Warning
Unresolved reference in doxygen comment Warning
Unused result of a nodiscard function Warning
Using the result of an assignment as a condition Warning

Redundancies in Code (24 inspections)

Code inspections in this category look for redundancies and dead code, which affect code readability and style, and could be safely removed. Some code redundancies cannot be fixed automatically, and quick-fixes for them are performed in the interactive mode, requiring the user input. But the majority of the redundancies can be fixed without user interaction, using either fix in scope or code cleanup.
