(a)
Create a Structure inventory which contains the following:
- A character array partName[30]
- An integer partNumber,
- A floating point price
- An integer stock
- An integer reorder.
(a)
Explanation of Solution
Explanation:
A structure is a user defined data type which contains related variables which have same name.
Following syntax is used to create a structure with a keyword struct:
struct <structure name> { variable 1; variable 2; ---; };
Structure named Inventory with the given variables is defined as follows:
struct Inventory { char partName[30]; int partNumber; float pointprice; int stock; int reorder; };
(b)
Define the union data containing char c, short s, long b, float f and double d.
(b)
Explanation of Solution
Explanation:
Union is a user defined data type which contains related variables just like structure which uses same data space for its variable.
Following syntax is used to create an Union data type:
union <union name> { variable 1; variable 2; ---; };
Union named data which contains char c, short s, long b, float f and double d is defined as follows:
union data { char c; short s; long b; float f; double d; };
(c)
Create a structure called address that contains character arrays
- streetAddress[ 25]
- city[ 20 ]
- state[ 3]
- zipCode[ 6].
(c)
Explanation of Solution
Explanation:
A structure is a derived defined data type which contains related variables which have same name.
Following syntax is used to create a structure with a keyword struct:
struct <structure name> { variable 1; variable 2; ---; };
Structure with the name address containing character arrays is defined as follows:
struct address { char streetAddress[25]; char city[20]; char state[3]; char zipCode[6]; };
(d)
Create a structure student that contains the following :
- An character array firstName[15]
- An character array lastName[15]
- variable homeAddress of type struct address.
(d)
Explanation of Solution
Given Information
Structure named address as follows:
struct address { char streetAddress[25]; char city[20]; char state[3]; char zipCode[6]; };
Explanation:
A structure is a derived defined data type which contains related variables which have same name but each variable in the structure has its own data space.
Keyword struct is used to create a structure as follows:
struct <structure name> { variable 1; variable 2; ---; };
Structures can be used to declare variable which can access variables of the structure with the use of following syntax:
struct <structure_name><variable_name>;
Structure name Student which contains a structure
A structure student that contains the variable homeAddress of type struct address along with character arrays firstName and lastName is defined as follows:
struct student { char firstName[15]; char lastName[15]; struct address homeAddress; };
(e)
Create a structure test which contains a 16 bit fields with widths of 1 bit. The names of the bit fields are the letters a to p.
(e)
Explanation of Solution
Explanation:
Bit fields can be defined in the structure which enables user to specify the number of bits a unsigned or int member of variable can store.
Bit fields are defined with the following syntax:
<data type> <bit-field name> <number of bits>
A structure test which contains a 16 bit fields with widths of 1 bit is defined as follows:
struct test { unsigned int a : 1; unsigned int b : 1; unsigned int c : 1; unsigned int d : 1; unsigned int e : 1; unsigned int f : 1; unsigned int g : 1; unsigned int h : 1; unsigned int i : 1; unsigned int j : 1; unsigned int k : 1; unsigned int l : 1; unsigned int m : 1; unsigned int n : 1; unsigned int o : 1; unsigned int p : 1; };

C How To Program, Global Edition
- C++ Student Data Write a program that uses two structures Name and Student to store the following information for multiple students: Create a nameType structure that consists of First Name, Middle Initial, and Last Name Create a studentType structure that contains student information (Include the nameType structure within the Student information structure): Name ID email GPA Program (an enum type named programType containing programs such as CSCI, DBMS, INFM, SDEV) Suppose that a class has at most 20 students. Use an array of 20 components of type studentType. You will read in the names, id, and email from classroster.txt. The first line of the file will tell you how many students are in the class. To get the the GPA and program for each student you will need to read from studentlist.txt. The second file will have the id, program, and GPA for all of the students in the department. That means that not every student from studentlist.txt will be in classroster.txt. You will…arrow_forwardFunction Description: Given a structure array with fields 'names', 'ASCI and 'points", return the name whose ASCII value is closest to its points (which is the coolest name). Notes: . There will never be a tie for the coolest name. . Do not compute the ASCII value of the names: it is given to you by the ASCII field. . Only the absolute value of the difference between ASCII value and points is considered. Hint: • You can index multiple char values from a structure using (struct.field) Examples: struct1= struct('names". ("Dwayne', 'Justin', "Peters), 'ASCI, (616, 637, 627). "points". (639, 651, 655)); ASCII 2 3 names Dwayne Justin' Peters coolestname = coolestName(struct1) coolestname "Justin' 616 637 627 points 639 651 655arrow_forwardIn c++ Create a structure named student with two attributes, name and cgpa.
