char_array.c：windbgのでダンプchar_array.exeで空のモジュールには228のシンボルがありますか？
char arr[1];
int main(void) { printf("%s\n", arr); return 0; }
記号：
私も空のprograme上記のようなので、多くのシンボルを持っていることを見つけるために驚い0:000> x char_array!*

、なぜ？
printfはErikの長いリストに加えて、書式文字列のためのインタプリタとすべてのネイティブデータ型の変換を多かれ少なかれ持つ必要があります。また、すべてのデフォルト設定を使用している場合は、コンソールにワイド文字が表示されますが、狭い文字が印刷されるため、結果を即座に翻訳する必要があります。誰がコードが何をしているかをいつも簡単に見ることができるので、CはC++より優れていると誰が言ったのですか？ :-) –
