1. Display Function Implement a function to display the contents of the patient_list array. Add code to call this function. Note that there are multiple places where this function needs to be called. Look for the // TODO comments to find the correct locations. 2. Sorting the array by Age Implement the code to sort the contents of the patient_list array based on the value stored in the age field. To do this you will need to implement code that relies on the qsort function from the C Standard library A function that compares two patient elements, based on the value stored in the age field. A call to the qsort function, which includes the array to be sorted, the number of elements in the array, the size of each array element and the function used to compare the array elements. Add code to call the qsort function, using the age comparison function that you implemented. This code should be placed just under the appropriate // TODO comment in main(). Sorting the array by Balance Due Implement the code to sort the contents of the patient_list array based on the value stored in the balance field. To do this you will need to implement code that relies on the qsort function from the C Standard library (see http://www.cplusplus.com/reference/cstdlib/qsort/). As shown in the reference, this code requires two parts: A function that compares two patient elements, based on the value stored in the balance field. A call to the qsort function, which includes the array to be sorted, the number of elements in the array, the size of each array element and the function used to compare the array elements. Add code to call the qsort function, using the balance comparison function that you implemented. This code should be placed just under the appropriate // TODO comment in main(). Sorting the array by Patient Name Implement the code to sort the contents of the patient_list array based on the value stored in the name field. To do this you will need to implement code that relies on the qsort function from the C Standard library (see http://www.cplusplus.com/reference/cstdlib/qsort/). As shown in the reference, this code requires two parts: A function that compares two patient elements, based on the value stored in the name field. Because name data is stored in an array of characters, you cannot use the relational operators (<, >, <=, … ) to do the comparison, instead you should use a function from the C Standard Library to determine the order of the names, see (http://www.cplusplus.com/reference/cstring/strncmp/). A call to the qsort function, which includes the array to be sorted, the number of elements in the array, the size of each array element and the function used to compare the array elements. Add code to call the qsort function, using the name comparison function that you implemented. This code should be placed just under the appropriate // TODO comment in main().

Question

1. Display Function

Implement a function to display the contents of the patient_list array.
Add code to call this function. Note that there are multiple places where this function needs to be called. Look for the // TODO comments to find the correct locations.

2. Sorting the array by Age

Implement the code to sort the contents of the patient_list array based on the value stored in the age field. To do this you will need to implement code that relies on the qsort function from the C Standard library

A function that compares two patient elements, based on the value stored in the age field.
A call to the qsort function, which includes the array to be sorted, the number of elements in the array, the size of each array element and the function used to compare the array elements.

Add code to call the qsort function, using the age comparison function that you implemented. This code should be placed just under the appropriate // TODO comment in main().

Sorting the array by Balance Due

Implement the code to sort the contents of the patient_list array based on the value stored in the balance field. To do this you will need to implement code that relies on the qsort function from the C Standard library
(see http://www.cplusplus.com/reference/cstdlib/qsort/). As shown in the reference, this code requires two parts:

A function that compares two patient elements, based on the value stored in the balance field.
A call to the qsort function, which includes the array to be sorted, the number of elements in the array, the size of each array element and the function used to compare the array elements.

Add code to call the qsort function, using the balance comparison function that you implemented. This code should be placed just under the appropriate // TODO comment in main().

Sorting the array by Patient Name

Implement the code to sort the contents of the patient_list array based on the value stored in the name field. To do this you will need to implement code that relies on the qsort function from the C Standard library
(see http://www.cplusplus.com/reference/cstdlib/qsort/). As shown in the reference, this code requires two parts:

A function that compares two patient elements, based on the value stored in the name field. Because name data is stored in an array of characters, you cannot use the relational operators (<, >, <=, … ) to do the comparison, instead you should use a function from the C Standard Library to determine the order of the names, see (http://www.cplusplus.com/reference/cstring/strncmp/).
A call to the qsort function, which includes the array to be sorted, the number of elements in the array, the size of each array element and the function used to compare the array elements.

Add code to call the qsort function, using the name comparison function that you implemented. This code should be placed just under the appropriate // TODO comment in main().
