函数的递归与嵌套

#include<stdio.h>void print(int *arr,int n){int i;printf("排序后的数组为\n");for(i=0;i<n;i++){printf("arr[%d]=%d\t",i,*(arr+i));printf("\n");}return ;}void sort(int *arr,int n){int i,j,k,temp;for(i=0;i<n-1;i++){k=i;for(j=i+1;j<n;j++){if(arr[j]<arr[k]);k=j;}if(k!=i){temp=arr[i];arr[i]=arr[k];arr[k]=temp;}}print(arr,n);return ;}void main(){int arr[8];int i;for(i=0;i<8;i++){printf("请输入arr[%d];",i);scanf("%d",&arr[i]);}sort(arr,8);return ;}

#include<stdio.h>void Test(){int sum=1;int i=1;for(;i<10;i++){sum=(sum+1)*2;}printf("%d",sum);printf("\n");}int main(){Test();system("pause");return 0;}
