Code Inspection and Quick-Fixes in C++

Create from usage

If you use an undeclared symbol, ReSharper suggests one or more quick-fixes for creating the symbol based on the usage:

Create declaration

If a member function in a C++ file does not have declaration in the header file, ReSharper helps you create the missing declaration according to the signature of the implementation:

Add missing #include directive

If you use a symbol that is defined in the standard libraries or elsewhere in your solution, ReSharper helps you add the missing #include directives automatically:

You can use the Show popups for import actions checkbox on the Code Editing | C++ | Inspections page of ReSharper options (Alt+R,,O) to disable the popup. If the checkbox is not selected, the corresponding action will be available in the action list on Alt+Enter.

Add forward declaration

ReSharper can also generate a forward declaration for an unresolved symbol:

Remove unused #include directives

All unused #include are highlighted and can be easily removed with a quick-fix:

Initialize variable

ReSharper detects uninitialized variables and helps initializing them with the default value:

Replace the dot (.) with arrow (->) and vice versa

If the dot . operator is erroneously applied to a pointer, ReSharper helps you replace it with the arrow -> operator:

The reverse quick-fix is also available:

Change variable type

If the specified type of a variable or a field does not match to the assigned value, ReSharper provides a quick-fix to use the correct type in the declaration:

Change return type

If a function return type does not match the value it actually returns, ReSharper lets you quickly fix the return type:

Initialize members

If ReSharper detects uninitialized type members, it suggests initializing all members in one fix. You can also use the sub-menu of this fix to generate initializations for specific members.
