printf和scanf函数用法规则 ProgramDesigninCLanguage 格式输出：printf()函数和scanf()函数 •格式控制：由双引号括起来的字符串，用于指定要输出的数据的格式。它包括：1）普通字符：按原样输出的字符；2）格式说明：用来指定需输出数据的输出格式的，其形式为：%[<修饰符>]格式字符 格式字符用以说明输出数据的类型...
比如 scanf（“%d”,a）; printf("%df",a);输入1 【计算机按整形类型读入数据，然后在以a为名的4个字节的内存单元中以二进制存入数据,然后printf 从内存读取数据，按整形输出到屏幕】。。。是否可以这样理解？师否可以分的更细？输出到屏幕的1 是什么？是字符吗？主要是看到sprintf函数...
