indent工具可以把代码格式化成某种风格
$ indent -kr -i8 main.c
$ cat main.c
#include
#include
#include
int main(void)
{
char gesture[3][10] = { "scissor", "stone", "cloth" };
int man, computer, result, ret;
srand(time(NULL));
while (1) {
computer = rand() % 3;
printf
("\nInput your gesture (0-scissor 1-stone 2-cloth):\n");
ret = scanf("%d", &man);
if (ret != 1 || man < 0 || man > 2) {
printf("Invalid input!\n");
return 1;
}
printf("Your gesture: %s\tComputer's gesture: %s\n",
gesture[man], gesture[computer]);
result = (man - computer + 4) % 3 - 1;
if (result > 0)
printf("You win!\n");
else if (result == 0)
printf("Draw!\n");
else
printf("You lose!\n");
}
return 0;
}
-kr选项表示K&R风格，-i8表示缩进8个空格的长度
