## CS140--Homework 5

Note that the function header for problem 5 has changed!!! You are now passed both a pointer to the list and a pointer to the node to be deleted.

1. Suppose you are given the following declarations:
```      Jval val;
int age;
double salary;
char *name;
struct node *ptr;
```
1. Write a statement that assigns the variable age to val
2. Write a statement that assigns the variable salary to val
3. Write a statement that assigns the variable name to val
4. Write a statement that assigns the variable ptr to val
5. Write a statement that assigns the value in val to ptr

2. Write a union that contains an integer field named age, a pointer to a character string named address, and a three element integer array named test_scores.

3. The personnel department at State University has to keep track of three types of people: students, professors, and staff. The information it must keep about these groups is as follows:

1. All three groups of people have an integer social security number, a name of at most 20 characters, and a single character code that denotes whether they are male or female.

2. Students have a floating point gpa, a floating point fee balance, and a pointer to a list of courses they are taking. The pointer points to a struct course node.

3. Professors have a floating point salary, a single character code that denotes their rank, a 10 character string that denotes their office, and a pointer to a list of courses they are teaching. The pointer points to a struct course node.

4. Staff have a floating point hourly rate, an integer that denotes their job classification, and a 10 character string that denotes their office.

• Write a union declaration that allows a student, professor, and staff member to share the same memory space. The union declaration should only contain the information unique to each group. You will have to use structs to represent the unique information for each of the three groups.

• Write a struct named employee that includes the union, the additional shared fields, and a type indicator for the type of person being stored.

```          void sll_delete_node(Sllist list, Sllist node_to_delete);
