Question

#define N 20 fun(int a[],int n,int m) {int i; for(i=m;i>n;i-

Answer 1

#include

//a[N] 1,2,3,4,5,6,7,8,9,10,0,0,0..

//从a[0+1]开始移动后：1,2,2,3,4,5,6,7,8,9,10,0,0..

//输出前五个：1,2,2,3,4

#define N 20

fun(int a[],int n,int m)//a[]元素后移,从a[n+1]到a[m]

{

int i;

for(i=m;i>n;i--)

a[i+1]=a[i];

return m;

}

void main()

{

int i,a[N]={1,2,3,4,5,6,7,8,9,10};

fun(a,0,N/2);

for(i=0;i
