... in the above code signifies you can pass more than one argument to printf(). printf() Parameters The printf() function takes the following parameters: format - pointer to a null-terminated string (C-string) that is written to stdout. It consists of characters along with optional format...
Write formatted output using a pointer to a list of arguments. These functions are versions ofvsnprintf,_vsnprintf,_vsnprintf_l,_vsnwprintf,_vsnwprintf_lwith security enhancements as described inSecurity features in the CRT. Syntax CCopy

The main difference betweenprintf_sandprintfis thatprintf_schecks the format string for valid formatting characters, whereasprintfonly checks if the format string is a null pointer. If either check fails, an invalid parameter handler is invoked, as described inParameter validation. If execution is ...
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
Each field in the format specification may be a single character or a number which specifies a particular format option. Thetypefield is a single character that specifies whether the argument is interpreted as a character, string, number, or pointer, as shown in the following table. ...
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 ...
