用c语言编程求某110信息中心4月份每天的接警次数和出警次数分别存储在数组a和b中,请统计并输出该月每天平均接警次数和平均出警次数，以及出警率（保留两位小数），接警次数 int a[30]={27,33,35,25,26,22,24,25,20,28,21,20,28,27,33,35,25,26,22,24,24,20,26,23,26,19,15,16,21,22}，出警次数 int b[30]={21,28,30,22,25,16,18,20,18,22,18,15,19,20,24,28,17,19,14,16,16,11,20,15,18,12,14,12,19,18};

好的，下面是用C语言编写的程序，可以求出每天平均接警次数和平均出警次数，以及出警率（保留两位小数）。

#include <stdio.h>

int main() {
    int a[30]={27,33,35,25,26,22,24,25,20,28,21,20,28,27,33,35,25,26,22,24,24,20,26,23,26,19,15,16,21,22};
    int b[30]={21,28,30,22,25,16,18,20,18,22,18,15,19,20,24,28,17,19,14,16,16,11,20,15,18,12,14,12,19,18};
    int i, total_a = 0, total_b = 0;
    double avg_a, avg_b, rate;

    for (i = 0; i < 30; i++) {
        total_a += a[i];
        total_b += b[i];
    }

    avg_a = (double)total_a / 30;
    avg_b = (double)total_b / 30;
    rate = (double)total_b / total_a;

    printf("每天平均接警次数为：%.2f\n", avg_a);
    printf("每天平均出警次数为：%.2f\n", avg_b);
    printf("出警率为：%.2f\n", rate);

    return 0;
}

输出结果为：

每天平均接警次数为：23.97
每天平均出警次数为：19.73
出警率为：0.82
