Warm up exerciseswe will discuss the following

Linking a libarary into a Visual Sydio Project (must use VS 2010 or 2015)

Use of && and ||

? : operator

struct

define a structure for student records. fields you needname, id, gpa, major

assign data to this derived data type struct student using dot operator

declare struct student pointer and assign the address of a structure to the pointer

declare an array of 10 struct students

write a function which is passed an array of struct student and the size of the array and computes the average GPA of all the students

write a function which is passed an array of struct student and the size of the array and computes the average GPA of all students with the major ECE

Lab 10 (this is to be turned in)

You need to download the following

Lab10.c,

Lab10_main.c and

Lab10.h.

In this lab we will have 3 files, lab10.c, lab10_main.c and lab10.h. All your work will be done in the lab10_main.c, you don't need to modify lab10.h and lab10.c. The program consists of two array list[], this is an array of char pointers and STRList[] this array is an array of struct cellData.

Each char pointer is list points to a string of the form

Name^Account Number^STATE^Area Code^Mobile Number^Balance

Example

Name Here^2134^IN^317^3411122^245.67

You are to write two functions

ComputeAverageListBalance and SortListByBalance that will operate on the list []

double computeAverageListBalance(char *list[], int listsize);

void sortListByBalance(char * list[], int listsize);

Each array elements in the array STRList have the following format :

struct cellData{

char Name[50];

char account[5];

char state[3];

char areaCode[4];

char mobileNumber[8];

double balance;

}

The account number is unique and it is 3 or 4 digits, the state is a two character abbreviation, the area code is 3 digits, the mobile number is 7 digits and the balance is a floating value

In this part of the your program you are asked to calculate the average of the balances and to sort based on the balance, compute average balance of all accounts with a 317 area code

You should declare and define the following functions :

double computeAverageBalance(struct cellData list[], int listsize);

void sortByBalance(struct cellData list[], int listsize);

double computeAverageBalance_with_317(struct cellData list[], int listsize);

Your main (it is provided to you) should look like this

int main()

{

struct cellData list[25]={NULL};

int seed=715;

int i,listsize;

listsize= generate_list(list, seed);//I wrote in lab9.c generates random strings

printf(" original list *************** ");

for(i=0;i< listsize; i++)

printf("%s ",list[i]);

printf(" sort by balance *************** ");");

sortByBalance(list, listsize);

for(i=0;i< listsize; i++)

printf("%s ",list[i]);

printf(" ");

printf("the average balance is %.2lf \m", computeAverageBalance(list, listsize));

printf(" sort by Account Number *************** ");");

sortByAccountNumber(list, listsize);

for(i=0;i< listsize; i++)

printf("%s ",list[i]);

printf(" ");

quit(list, listsize); //I wrote in lab9.c ignore but needed

}

The function generate_list will generate a random list of size listsize (which is <=25). This is written for you in lab9.c

You need to write your functions (they have a shell of the function) in lab9.c
