文档介绍：项目实训一
实训内容:
1、定义一种数组a[11],用以寄存学生旳成绩。
2、从键盘输入10个学生成绩
3、采用冒泡法，将学生成绩按照从高到低进行排序
4、再输入一种学生旳成绩，将此成绩按照排序规律插入原学生成绩数组
5、将num_init<=9;num_init++)
    {
        printf("%d)input:",num_init+1);
        scanf("%d",&a[num_init]);
    }
    for (num_sort_2=1;num_sort_2<10;num_sort_2++)
    {
        for (num_sort_1=num_sort_2;num_sort_1>=1;num_sort_1--)
