Question

Write a C program with call to functions to produce the output given below.

// the requirements are that there should be 5 files; intList.h, intList.c, hw3.h, hw3.c, and main.c. please only C and use Linked List. thank you. For the 5 different files, he wants it this way:
1) main.c This file just consists of the main() function, which only consists of the displayClassInfo() function call, and the runMenuHw3() function call.
2) intList.h This file would have the IntNode struct definition, typedefs, and prototypes of the functions that directly manipulate your linked list, like the inserts, removes, etc.
3) intList.c This file would have the definitions of the functions that you prototyped in the intList.h file
4) hw3.h This file would have the prototypes of the functions like displayClassInfo(), runMenuHw3(), getLIWLUDigitCount(), etc. (and any other functions you want to create that don’t directly manipulate your linked list, but maybe help you in some other way to get the hw done.)
5) hw3.c This would contain the definitions of the functions that you prototyped in the hw3.h file above.

The program should display this output :

******************************************

MENU – HW #3 *   
1. getLIWLUDigitCountYourName() *
2. Quit *
******************************************

Select an option (use integer value only): -4

You are very funny here!

******************************************

MENU – HW #3 *   
1. getLIWLUDigitCountYourName() *
2. Quit *
******************************************

Select an option (use integer value only): 1

Do you have an integral value (1 for yes OR 0 for no)? 1

Enter the value: 1004

Do you have an integral value (1 for yes OR 0 for no)? 1

Enter the value: -2103451

Do you have an integral value (1 for yes OR 0 for no)? 1

Enter the value: 80645

Do you have an integral value (1 for yes OR 0 for no)? 0

The working list has 3 values of

1004

-2103451

80645

Calling getLIWLUDigitCountYourname() with one argument of

(1) A list of int’s
(2) The listing of values from front to end
1004
-2103451

80645

For individual values – 1004 has 3 unique digits.

-2103451 has 6 unique digits.

80645 has 5 unique digits.

After the function call was completed and a value was returned.

(1)The largest unique digit count (LUDC)is 6; and

(2) -2103451 is the largest integer with a LUDC of 6.

main.c file : Since it is not clearly mentioned what displayClassInfo() function does, so I have used it as displaying the initail menu for the user.

#include "hw3.c"

int main()
{
    int opt = -1;
    while(opt != 2)
    {
        opt = displayClassInfo();
        runMenuHw3(opt);
    }
}
