c语言中printf和scanf，C语言printf跟scanf的区别

对于c语言中printf和scanf，C语言printf跟scanf的区别，很多网友还不是很明白，今天艾巴小编收集了这方面的知识，就将其分享出来。

如scanf ("%d"，a)；printf(’，a)；输入1【计算机根据整形类型读取数据，然后将数据二进制存储在一个名为A的4字节存储单元中，然后printf根据整形从存储器中读取数据并输出到屏幕上】。可以这么理解吗？划分可以再细一点吗？输出到屏幕的1是什么？是人物吗？主要看sprintf函数，如下：char first[MAX]；char last[MAX]；char formal[2 *最大10]；浮动奖；puts('输入名字')；

Get (the first); Puts ('Enter Last Name'); Get (the last one); Puts ('input bonus'); Scanf('%f' prize); Sprintf (official,' %s %-19s:$%6.2f\n' surname, first name, award); //Inconsistent data types, prizes and official put (official); Why can I store the implementation data in a character array? I don't quite understand. -Solution-Format Specification Fields: The format specification consisting of optional and required fields of printf and wprintf functions has the following form:

% [logo] [width] [. Accuracy] [{h-solution-li64l}] Each field of the type format specification is a single character or number representing a specific format option. The simplest format specification contains only a percent sign and a type character (for example, %s). If the percent sign is followed by a character with no format field meaning, the character is copied to stdout. For example, to print the percent sign character, use%%.

Optional fields appear before the type character, which controls other aspects of the format, as follows: type requires characters, and determines whether the related parameters are interpreted as characters, strings or numbers (see Table R.3). Optional characters that control the output and print alignment of symbols, spaces, decimal points, octal and hexadecimal prefixes. Multiple flags can appear in a format specification.

Width Optional number, which specifies the minimum number of characters to output. (see printf width specification. ) precision optional number, which specifies the maximum number of characters to be printed for all or part of the output field, or the minimum number of digits to be printed for integer values (see Table R.5). The optional prefix of type- specifies the size of the parameter (see Table R.6).
