Question

In C only Please!

This lab is to write a program that will sort an array of structs.

• Use the functions.h header file with your program.

• Create a source file named functions.c with the following:

  • A sorting function named sortArray. It takes an array of MyStruct's and the length of that array. It returns nothing. You can use any of the sorting algorithms, you would like though it is recommended that you use bubble sort, insertion sort, or selection sort as they are the easiest to implement. You will sort on the integer data member.
  • A printing function named printArray. It takes an array of MyStruct's and the length of that array. It returns nothing. It will simply print the integer data member and the string data member separated by a space with each array element on a separate line. Here is an example of the output:

• Create a main.c source file with the main() that will do the following:
  • Prompt the user for the number of elements they want in the array
  • Dynamically allocate an array of MyStruct's of that size the user entered
  • Prompt the user for an integer and string to input into each element of the array
  • Call sortArray() on the array to sort it.
  • Call printArray() on the array to print out the values

Example output:

10 Epsilon

15 Eta

20 Beta
