代码格式化命令—indent: indent –h.c –o h2.c -gnu -br

//h.c
#include
int main(void){printf("Hello World!/n");if(1>2){printf("1>2/n");}while(1<0){printf("1<0");}for(;1<0;){printf("1<0");}return 0;}
indent –h.c –o h2.c –gnu –br
//h2.c
#include
int
main (void)
{
  printf ("Hello World!/n");
  if (1 > 2) {
    printf ("1>2/n");
  }
  while (1 < 0) {
    printf ("1<0");
  }
  for (; 1 < 0;) {
    printf ("1<0");
  }
  return 0;
}
