C语言实现回文数判断及偶数回文数查找

#include <stdio.h>

// 判断是否为回文数
int loop(int x) {
    int temp = x, reverse = 0;
    while (temp > 0) {
        reverse = reverse * 10 + temp % 10;
        temp /= 10;
    }
    return reverse == x;
}

int main() {
    int a, b;
    scanf('%d%d', &a, &b);
    for (int i = a; i <= b; i++) {
        if (i % 2 == 0 && loop(i)) {
            printf('%d ', i);
        }
    }
    printf('
');
    return 0;
}
