In this program, you will work with a structure representing a LEGO building set, which is defined as follows $($from LegoSet.h$)$:

typedef struct $\{$

char name$[50]$; $//$ Name of set

unsigned num; $//$ Set number

unsigned pieces; $//$ Number of pieces in set

unsigned minAge; $//$ Minimum recommended age

unsigned maxAge; $//$ Maximum recommended age

$\}$ LegoSet;

You must complete the main function in exam$3\_$struct$\_$main.c as well as the three function definitions in LegoSet.c$.$

Your final program should recognize three commands:

age: Prompt the user to enter an age and print all sets that are appropriate for someone of that age $($in other words, the age input is between the minimum and maximum age for that set, including those endpoints$)$ using the findByAge$()$ function described below:

void findByAge$($LegoSet list$[],$ unsigned n$,$ unsigned a$)$: takes in an array of LegoSet structures, list, the number of structures in the array, n$,$ and the desired age, a$.$ Function prints all age$-$appropriate sets found in list, as well as the total number of sets that were printed. For example, if I enter age $4,$ the output would be:

Enter age: $4$

Classic Large Creative Brick Box $($#$10698)$

$790$ pieces

Ages $4$ and up

Disney Ariel's Celebration Boat $($#$43191)$

$114$ pieces

Ages $4-10$

DUPLO Town Farm Tractor & Animal Care $($#$10950)$

$27$ pieces

Ages $2-5$

Total sets for age $4$: $3$

largest: Find and print the set with the most pieces in an array of LegoSet structures using the largestSet$()$ function described below:

unsigned largestSet$($LegoSet list$[],$ unsigned n$)$: takes in an array of LegoSet structures, list, and the number of structures in the array, n$.$ Function returns the index of the structure with the most pieces.

exit: Exit the program

In addition, you must write one more function:

void printSet$($LegoSet$*$ ls$)$: Given a pointer to a LegoSet structure, print the contents of that structure to match one of the two formats below. If the maximum age in the structure is $99,$ the output should match this form, showing only the minimum age:

Tree House Building Kit $($#$21318)$

$3036$ pieces

Ages $16$ and up

Otherwise, the last line should list both the minimum and maximum ages, as shown below:

Disney Ariel's Celebration Boat $($#$43191)$

$114$ pieces

Ages $4-10$

Your program does not have to check for any errors$--$the partially written main function already handles error checking.
