数组定义已经自动初始化
数组的插入排序：
1 #include <stdio.h>
2 int main()
3 {
4
5 int a[11]={1,4,6,9,13,16,19,28,40,100};// 10 member
6
7 int temp1,temp2,number,end,i,j;
8
9 printf("original array is:\n");
10
11 for(i=0;i<11;i++) // output 11 member,if a[10]==0,it indicate it was init already
12
13 printf("%5d",a[i]);
14
15 printf("\n");
16
17 printf("insert a new number:");
18
