An occurrence of a pointer-to-character type in C++ code.
Bounded character arrays are not considered to be
C-style strings for this warning class.
Howevever, note that a function parameter declared as a character
array will decay to a pointer-to-character, so will trigger a
warning of this class.

| 有効/無効設定 | このワーニングクラスのチェックはデフォルトで無効になっており、プロジェクトには非正規の C向けAST
が必要になります。有効にするにはプロジェクト設定ファイル (configuration file) に以下の WARNING_FILTER ルールと
RETAIN_UNNORMALIZED_C_AST 設定を追加してください。
RETAIN_UNNORMALIZED_C_AST = Yes WARNING_FILTER += allow class="C String" |
