用c语言实现插入排序

//insert_sort: the first example in the <introduction to algorithms> in chapter2

#define N 10

#include<stdio.h>

int main()

{
int key,j;
int a
={6,1,8,5,3,7,9,4,2,0};
for(int i=1;i<N;i++)
{
key=a[i];
j=i-1;
while(a[j]>key&&j>=0)
{
a[j+1]=a[j];
j--;
}
a[j+1]=key;

}
for(int i=0;i<N;i++)
{
printf("%d\t",a[i]);
}
return 0;

}
