you can return multiple values from the function by using 
mechanism  called "call-by-reference".
for example:
  
void main()
 {
    int area,*circumference;
    area=function(area,circumference);
    cout<<"the area is "<<area;
    cout<<"the circumference is"<<circumference;
 }
int function(int a,int *b)
 {
    a=12;
    int temp=a*3;
    b=&temp;
    return a;
 }

// this is just an example............


// you can also use array and return the adress of the 
array in the main and can use to traverse the entire array 
and return multiple values from function.
