Task 4 Convert the previous program to utilise multiple files. 1. Make a copy of your task3.c source file and name it task4a.c. 2. Open the files named task4b.h and task4b.c. 3. In task4a..*include the task4b.h header. 4. Migrate aspects of task4a to task4b oMove the struct declaration to task4b.h. Move the two functions prototypes, make_account and print earnings, to task4b.h. Modify the signature of the print earnings function to match the following void print_earnings (float deposit, struct account *options, int num): Move the definitions of make_account and print_earnings to task4b.c. Once again, modify the signature of the print earnings function to match the previous step 5. Fix the print_earnings function in task4b.c to work with its new parameters. You no longer have access to the options array or NUM_OPTIONS macro so you will have to loop through account options via the pointer reference. 6. Modify the call to print earnings in the main function of task4a.c to pass in the options array and size (NUM_OPTIONS). 7. Write a makefile to compile task4a.c and task4b.c. Refer to the lecture slides for an example of a makefile for multiple source files. You do not need to explicity compile the task4b.h header file; it will be compiled when one of the files it is included in is. Hint: You will need three rules: one to build the object files for task4a, one to build the object files for task4b, and one to link them together to form the final program: task4: task4a.o task4b.o gcc. task4a.o: gcc. task4b.o: gcc. 8. Compile your program with make. Verify the output is unchanged from Task 3
