答案是空格,证明如下,不逼逼,直接上代码:
//文件被命名为test.c
#include<stdio.h>
int main()
{
int a=2;
printf("%d\n",a);
return/*this is a pig*/0;
}
gcc编译,运行,console结果:
2
然后你把注释去掉,代码如下:
#include<stdio.h>
int main()
{
int a=2;
printf("%d\n",a);
return0;
}
gcc就开始抱怨了,如下:
test.c: In function ‘main’:
test.c:10:5: error: ‘return0’ undeclared (first use in this function)
return0;
^
test.c:10:5: note: each undeclared identifier
is reported only once for each function it appears in
综上,注释被编译器替换成了空格。
