用c写一个求三个数中两个最大数之和用if语句

#include <stdio.h>

int main() {
    int a, b, c;
    int max1, max2, sum;
    printf("请输入三个数：\n");
    scanf("%d%d%d", &a, &b, &c);

    if (a > b) {
        max1 = a;
        max2 = (b > c) ? b : c;
    } else {
        max1 = b;
        max2 = (a > c) ? a : c;
    }

    sum = max1 + max2;
    printf("两个最大数之和为：%d\n", sum);

    return 0;
}
