and then decide inside that method how to typecast integer to char* 不,你不能。 void *不包含类型信息,因此无法确定它实际指向的类型。 is the << operator overloaded for each and every type? 是 is there a way to achieve it through just one generic overloaded function? 这个问题没有意义..你...

Pointer Typecast: Typecasts data to (char *) because memchr() operates on byte-level data rather than integer arrays. Conditional Check: Checks if result is not NULL, indicating that target_byte was found in data. If found, it prints the hexadecimal value of target_byte and its offset in...
