每次循环遍历最小元素，将其与a[i] 交换
/*选择排序*/
#include<stdio.h>
void selectsort(int *a,int n)
{
int i;
int j;
int temp = 0;
int flag = 0;
for (i=0; i<n-1; i++)
{
temp = a[i];
flag = i;
for (j=i+1; j<n; j++)
{
if (a[j]<temp)
{
temp = a[j];
flag = j;
}
}
if (flag!=i)
{
a[flag] = a[i];
a[i] = temp;
}
}
}
int main()
{
int i = 0;
int a[] = {9,7,3,1,6,5,4,8,2,0};
int len = sizeof(a)/sizeof(a[0]);
selectsort(a,len);
for (i=0; i<len; i++)
{
printf("%d",a[i]);
}
printf("\n");
return 0;
