Answer / prasanta maiti

Make array of values and return the array address as long.
simple example:
void main()
{
int a[10],i,n;
int *new_value_array;
printf("\n Enter how many number you want to enter? ");
scanf("%d",&n);
for(i=0;i<n;i++)
sacnf("%d",&a[i]);
printf("\n old value of the array is:");
for(i=0;i<n;i++)
printf("\t%d",a[i]);
new_value_array = array_modify(a,n);
printf("\n new value of the array is: \n");
for(i=0;i<n;i++)
printf("\t%d",*(new_value_array+i));
getch();
}
int *array_modify(int a[10],int n)
{
int i;
for(i=0;i<n;i++)
a[i]=a[i]*4;
return(a);

How to return multiple values from a function? ..

Answer / splurgeop

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.
