Question

IN C++

struct elementType{

     int integer;

     float decimal;

   char ch;

};

struct nodeType{

   elementType e;

   nodeType* link:

};

Write a member functions that will find the range of values in a singly linked list. The range is returned to the calling function.

PLEASE USE THE STRUCT ABOVE

Answer 1

struct nodeType* findRange(struct nodeType *head)
{
     struct elementType min;
     struct elementType max;
    struct  nodeType** node= malloc(2 * sizeof(*nodeType));
     min.integer=INT_MAX;
     min.decimal=FLT_MAX;
     min.ch=CHAR_MAX;
      max.integer=INT_MIN;
     max.decimal=FLT_MIN;
     max.ch=CHAR_MIN;
     
     while(head!=NULL)
     {
        // find minimum range
        if(head->e.integer<min.integer)
        {
                min.integer=head->e.integer;
                }
                 
                 if(head->e.decimal<min.decimal)
        {
                min.decimal=head->e.decimal;
                }
                 
                 if(head->e.ch<min.ch)
        {
                min.ch=head->e.ch;
                }
                
                // for maximum
                if(head->e.integer>max.integer)
        {
                max.integer=head->e.integer;
                }
                 
                 if(head->e.decimal>min.decimal)
        {
                max.decimal=head->e.decimal;
                }
                 
                 if(head->e.ch>min.ch)
        {
                max.ch=head->e.ch;
                }
                 head=head->link;
         }
     
     struct nodeType arr[2];
     arr[0]=min;
     arr[1]=max;
     return arr;
        
}
