2) Array of structures, text files Please read the tutorial on handling files in C. Consider the following definitions. struct persalary{ int month; long salary; /* number 1 corresponds to January, *1 /* 2 corresponds to February, and so on */ struct employee int emp_no; /* Employee number */ char name[12]; /* Employee name */ struct persalary salaries[3]; /* three months salaries */ long maximum; /* Maximum of 3 months salaries */ float average; /* Average of 3 months salaries*/ }; A) Using the above structures, define an array empArray of structure employee with size 10 that will be initialized using a data file (named emp.txt). The data file should have 10 rows of data in it. The first four rows are given. The fifth row should contain your name. The remaining 5 rows should contain data that you make up.

Since the file has only 4 rows, there will be some empty places in your empArray. B) Write a function readFile that reads the data in the file into empArray. (10 pts) C) Write a function display that displays the contents of the array as shown below. Note that the integer values corresponding to months are converted to the proper month names. This can be achieved by declaring an array of the month names.

(20 pts) Employee No Name Average Maximum 121 Joe XXXX.XX XXXXXX 234 Ayse XXXX.XX 456 Mehmet XXXX.XX XXXXXX 875 Mary XXXX.XX XXXXXX XXXXXX E) What will be the total memory size of this array? Explain your answer. (5 pts) F) Assume that you declared allEmployee for 3 employees as follows struc employee allEmployee[3]; a) If the base address of this array is 1000, what the starting address of allEmployee[1].salaries[2].salary? (5 pts) b) If the base address of this array is 5000, what is the address of Mehmet's May salary? (5 pts) 2) Array of structures, text files Please read the tutorial on handling files in C.
