Write a program to take input for n number of doctor records and write records of all cardiologists in a file named: “record1”. Also write records of all those doctors in another file named: “record2” who are taking salary more than INR 80,000. After writing records in both files, merge their contents in another file: “finalrecord” and read all records of “finalrecord” file and display on screen. [Attributes of doctor: doc_id, doc_name, doc_specialization, doc_salary]

for (int x = 1; x <= 10; x++) {

for (int y = 10; y >= x; y--) {

if (y % 2 == 0) {

cout << "*";

}

else {

cout << "#";

Write a C++ program for a lecturer to convert all his (5 students) student marks to 

a percentage. Enter the total mark of the test, and then enter for each student his 

student number, and the mark obtained by the student. Display the student number, 

percentage, and status indicating whether the student passed (50% or more) or failed 

the test.

Include the following function and sub procedures (as shown in the table below):

LectureApp

NO METHOD NAME DESCRIPTION MARK

1 main This function prompts for the total and 

also invokes the required procedures to 

display the results.

7

2 getData This sub procedure prompts for the 

student number and mark obtained by the 

student from the end-user.

4

3 determinePercentage This function returns the mark obtained in

percentage.

4

4 determineStatus This function returns true if the student 

passed or false, otherwise.

6

5 printOutput This sub procedure displays the output as 

shown in the sample output.

Write a program to overload operators in the same program by writing suitable operator member functions for following expression:

07= ((01 % 02)>(03 || 04) - (05>06)) [Here 01,02,03,04,05,06 and 07 are objects of a class "overloading", and this class is having one integer data member]
