回答：这里的 pointer 指向的是一个字符串,字符串的首地址赋给 pointer printf("%s\n",pointer); //输出Hello World!// printf 遇到指向字符串的指 //针时,输出字符串(就是这样定义的) printf("%s\n",*pointer); //输出H printf("%d\n",pointer); //输出pointer指向的地址

A pointer in the target's virtual address space. The value of the pointer. %N DWORD_PTR (32 or 64 bits, depending on the host's architecture) A pointer in the host's virtual address space. The value of the pointer. (This is equivalent to the standard C %p character.) ...

The number of characters written, not including the terminatingNULL, or a negative value if an output error occurs. SeeBehavior summaryfor details. Remarks Each of these functions takes a pointer to an argument list, then formats the data, and writes up tocountcharacters to t...
If the l modifier is used, the argument is first converted to a character string as if by %ls with a wchar_t[2] argument. N/A N/A int wint_t N/A N/A N/A N/A N/A s Writes a character string The argument must be a pointer to the initial element of an array ...
Clearly the intention here is to print a representation of thepointertopixels, but sinceuint8_tis a character type the compiler would attempt to print it as a C string if we blindly fed it intooperator<<. To counter this kind of madness, tinyformat tries to static_cast any type fed to ...
nPointer to integerNumber of characters (bytes) successfully written so far to thestreamor buffer; this value is stored in the integer whose address is given as the argument. pPointerPointer converted to a sequence of printable characters. It can be one of the following: ...
