方法一:直接提取并逆序排列

```c

include

int main() {

int a, b, c, d;

// b为百位,c为十位,d为个位

scanf("%d", &a);

b = a / 100;

d = a % 10;

c = (a - 100 * b) / 10;

printf("%d%d%d", d, c, b);

return 0;

}

```

方法二:通过加法运算逆序

```c

include

int main() {

int a;

scanf("%d", &a);

int reversed = 0;

reversed = 100 * a % 10 + 10 * (a / 10) % 10 + a / 100;

printf("%d", reversed);

return 0;

}

```

方法三:使用数学运算直接逆序

```c

include

int main() {

int n;

scanf("%d", &n);

int reversed = (n % 10) * 100 + ((n / 10) % 10) * 10 + (n / 100);

printf("%d", reversed);

return 0;

}

```

方法四:分离每一位并逆序

```c

include

int main() {

int x;

scanf("%d", &x);

int reversed = (x % 10) * 100 + ((x / 10) % 10) * 10 + (x / 100);

printf("%d", reversed);

return 0;

}

```

方法五:处理前导零

```c

include

int main() {

int x;

scanf("%d", &x);

int reversed = (x % 10) * 100 + ((x / 10) % 10) * 10 + (x / 100);

printf("%d", reversed);

return 0;

}

```

这些方法都可以实现逆序三位数的功能,可以根据个人喜好和需求选择合适的方法。
