求该程序修改
#include <iostream>

using namespace std;

int  main()
{
    int a[10]={1,2,4,5,7,8,10,23,24,58},
        b[10]={1,3,5,7,9,10,11,12,13,14},
        c[30];

    int k=0,i=0,j=0;
    for( ; ; )
    {
        
        if(a[i]<b[j])
        {
            c[k]=a[i];
            k++;i++;
        }
        else
        {
            c[k]=b[j];
            k++;j++;
        }
        if(i==10|| j==10)
            break;

    }

    if(i==10)
        for(;j<10;j++)
        {
            c[k]=b[j];
            k++;
        }

   if(j==10)
      for(;i<10;i++)
        {
            c[k]=a[i];
            k++;
        }



  int n;

  cout<<"请输入一个整数n"<<endl;

    cin>>n;

  cout<<"n = "<<n<<endl;

    if(n<=k)
   
     cout<<"第n个数为 "<<c[n-1]<<endl;

int search(a[10],c[n-1],10)    ;     
   

   

return 0;   
}


int search(int a[],int &x,int n)
{
        int left=0;

           int right=n-1;
           
           if(x==a[left] || x==a[right])
               
               cout<<"该数在a组"<<endl;

     
           else
           {
             while(left<=right)
             {

             int middle=(left+right)/2;

             if (x==a[middle]) cout<<"该数在a组"<<endl;

             if (x>a[middle]) left=middle+1;

             else right=middle-1;
             }
           }
           return 0;
}

恩。。
我运用了，解决了调用的问题了。。。

thanks！！！！
