Question

Write a function to find the largest number and the second largest number from an array. However, a
function cannot return multiple values. We need to use pointers to implement the function as follows:
void find_two_largest(int a[], int n, int *largest, int *second_largest);
When passed an array
a of length
n
, the function will search a for its largest and second
-largest
elements, storing them in the variables pointed to by largest
and
second_largest
, respectively.
The input is array’s size followed by the elements in the array.
The
maximum size of the
array is 10.
For
example:
4 5 6 7 8 9
The ou
tput should be:
Largest number: 9
Second largest number:8

Answer 1

Your logic is incorrect. Here,

if(a[i]> a[j])
{
a[i]= *largest;
this will assign undefined values to a[i],a[j] next because values are not assigned still to pointers..
If you trying a[i] to *largest then it must be like
*largest = a[i];
*second = a[j];

But actually, you need condition is
if(a[i] > *largest ) //for largest finding...
{
*largest=a[i];
}

Other simple way ,sort array first by
if(a[i]<a[j] )
{
//swap values between a[i],a[j].
}
a[0] will be largest and a[1] will be 2nd largest..

a[j]= *second_largest;
}

Answer 2

only one loop needed:
