c++直接用count直接调用函数

 1 #include<iostream>  2 #define M 1000  3 using namespace std;  4 int jiaoji(int a[M],int b[M],int n)  5 {  6 int i,j,k=0,c[M];  7 for(i=0;i<n;i++)  8  {  9 for(j=0;j<n;j++) 10  { 11  if(a[i]==b[j]) 12 { 13 c[k++]=a[i]; 14 continue; 15 } 16 } 17 } 18 for(i=0;i<k;i++) 19 cout<<c[i]<<" "; 20 } 21 int main() 22 { 23 int i,j,n,c[M],a[M],b[M]; 24 cin>>n; 25 for(i=0;i<n;i++) 26 cin>>a[i]; 27 for(j=0;j<n;j++) 28 cin>>b[j]; 29 cout<<jiaoji(a,b,n); 30 } 

cout<<jiaoji(a,b,n);
