"Hello world" in C without printf?
提问by user1869465
Is it possible to write a "hello world" program in C without the use of the printf function? (while still keeping the program relatively at a few lines)
是否可以在不使用 printf 函数的情况下用 C 编写“hello world”程序?(同时仍将程序相对保持在几行)
回答by Michael Dickens
This should work:
这应该有效:
int main (void)
{
puts("Hello, World!");
return 0;
}
Why don't you want to use printf? I can't think of any reason not to.
你为什么不想使用 printf 呢?我想不出任何不这样做的理由。

write(stdout, "hello world", strlen("hello world"));

This is a ridiculous alternative to just using puts("hello world\n");
这是仅使用的荒谬替代方案 puts("hello world\n");
#include <stdio.h>
int main(void){
char *s="hello world\n";
while (*s) putchar(*s++);
}

Well, if we're going to include silly examples (yes, I'm looking at you, technosauraus), I'd go with:
好吧,如果我们要包含一些愚蠢的例子(是的,我在看着你,科技龙),我会选择:
#include <stdio.h>
void makeItSo (char *str) {
if (*str == '##代码##') return;
makeItSo (str + 1);
putchar (*str);
}
int main (void) {
makeItSo ("\ndlrow olleH");
return 0;
}
Just don't do this for really long strings or you find out what Stack Overflow reallymeans :-)
只是不要对很长的字符串执行此操作,否则您会发现 Stack Overflow 的真正含义:-)
