这段代码的功能是对N个成绩进行排序,计算不及格人数、平均成绩和最低成绩。
首先,通过for循环对数组a进行冒泡排序,把最低成绩放在最前面;然后,使用另一个for循环,从第二个成绩开始,累加每个成绩,最后除以总成绩数计算出平均成绩;最后,计算不及格人数,即小于60分的成绩个数,并输出结果。 -

这段代码通过调用函数fun()来计算一组整型数组(score)的平均成绩、最低成绩以及不及格人数。
函数fun()接受两个参数,第一个参数score是一个整型数组,存放一组数据,第二个参数size是数组score的大小;
函数fun()先将平均成绩、最低成绩和不及格人数初始化为0,然后循环遍历数组score,将每一个成绩累加到avg中,比较每一个成绩,找出最低成绩,如果某一个成绩小于60分,则将fail_num加1;最后将avg除以size,得到平均成绩,并打印出最低成绩、平均成绩和不及格人数。
