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
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 exec...
Legal for integer conversions (d, i, o, u, x, or X conversion letters), specifies the matching argument is asigned charfor d and i, andunsigned charfor o, u, x, and X. For annconversion letter the matching argument is a pointer to asigned char. (New as of C99.) ...

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. ...
Each of these functions takes a pointer to an argument list, and then formats and writes the given data to the memory pointed to bybuffer. The versions of these functions with the_lsuffix are identical except that they use the locale parameter passed in instead of the current thread locale...
The first limit isFOPEN_MAX, which applies to streams opened withfopen(). Streams are represented by aFILEpointer. The three standard streams stdout, stdin, and stderr count against this total, so ifFOPEN_MAXis 10, you may only open 7 more streams without closing one of them. If too man...
These higher-order functions allow for better flexibility of use: You can decide to do different things with the individual output characters: Encode them, compress them, filter them, append them to a buffer or a file, or just discard them. This is achieved by you passing a pointer to your...
