C++ function return array

To enable a function to return an array (a collection of values), you will need to place the * sign in front of the function name when it is declared and defined. Then in the function call, you can use a pointer to point to returned array of that function.

#include <iostream>
#include <conio.h>
using namespace std;

int *readdata(int arr[],int n){
for(int i=0;i<n;i++){
cout<<"value"<<i<<":";
cin>>arr[i];
}
return arr;
}

int main(){
   int arr[10];
   int *p;
   p=readdata(arr,10);
   for(int i=0;i<10;i++)
        cout<<*(p+i)<<"\t";
  
   getch();
   return 0;
}
