Question

编写一个排序函数sort(),完成将N个数按从小到大的顺序排序。N个元素在主函数中输入，排序后

Answer 1

#include<stdio.h>
void sort(int *p,int n);
int main()
{
int i,arr1[6]={3,9,2,8,6,1},arr2[10]={11,5,18,7,2,15,4,13,9,3};
sort(arr1,6);
sort(arr2,10);
printf("排序的结果:\n");
for(i=0;i<6;i++)
printf("%3d",arr1[i]);

printf("\n");
for(i=0;i<10;i++)
printf("%3d",arr2[i]);
}

void sort(int *p,int n)
{
int i,j,temp;
for(i=0;i<n-1;i++)
for(j=i+1;j<n;j++)
if(p[i]>p[j])
{
temp=p[i];
p[i]=p[j];
p[j]=temp;
}
}
