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。
