A c=getchar()!=EOF 实际上是c=(getchar()!=EOF), 因为后面的表达式是个判定, 所以结果不是1就是04. D ''不能作为常量, 因为本身不合法; '80' 里面太多东西了; '%d'同理---补充, 你不能直接把putchar(c), 你要转化为int以后再输出#include void main(){ int a; char c; c = getchar...
putchar(c); c=getchar(); } } 上述这段代码中,c = getchar(); 会将getchar()的返回值int强制转化为char类型,就将32位的int截断为8位的char。之后的 c != EOF,又会将c强制转化为int类型,就将8位的char类型进行扩展,扩展为32位int类型。在扩展时,如果char类型为无符号数,进行零扩展,如果char类型为...
while((c = getchar()) != EOF){ putchar(c); } 这一段代码是The C Programming Language(Second Edition)中一个经典的代码,很多初学者在看到这段代码时会有不少疑问,这里做一个简单的总结。 一、getchar的两点总结 getchar是以行为单位来读取的。
The standard C library provides several functions and macros for character 1/0. Here we consider the getchar and putchar macros. As these macros read or write a single character, they are typically used in a loop to read/write a sequence of characters.
例如：如果输入为abcdefghijkl输出也是一样的abcdefghijkl如果你不想要这种行为，你可以在putchar(c);之...

int c; c = getchar(); while (c != EOF) { putchar(c); c = getchar(); } } To my understanding, the conduct of getchar() can be characterized in the following manner: In case stdin buffer is empty, the operating system can receive input from the user until [enter] is pressed...
