Question

What is the output, if any, of each of the following C++ statements? (3, 4)
a. cout << current->info;
b. current ¼ current->link;
cout << current->info;
c. cout << temp->link->link->info;
d. trail->link ¼ nullptr;
cout << trail->info;
e. cout << last->link->info;

Consider the linked list shown in Figure 16-50. me that the nodes are in the usual info-link form. Use this list to answer Exercises 6 through 14. If necessary, declare additional variables. (Assume that list, current, temp, trail, and last are pointers of type nodeType. list temp current trail last FIGURE 16-50 Linked list for Exercises 6 through 14

Explanation / Answer

What is the output, if any, of each of the following C++ statements? (3, 4)
a. cout << current->info; //current is pointing to first node, and therefore, current->info will print 75.
b. current ¼ current->link; //I believe this is = symbol, which will move the current to the next node, i.e., a node with value 35.
cout << current->info; //Now current->info will print a value of 35.
c. cout << temp->link->link->info; //temp is pointing to a node with value 86, and therefore, temp->link is pointing to a node with value 10, temp->link->link is pointing to a node with value 50. So, a value of 50 will be printed to screen.
d. trail->link ¼ nullptr; //trail->link = nullptr. This will just disconnect the last node i.e., a node with value 39.
cout << trail->info; //trail->info is 65.
e. cout << last->link->info;   //last->link is grounded, i.e., is pointing to null, and will not have info part.
