PLease make this program work in C++ // This program has three functions: main, beep, and beeper   #include using namespace std; // Definition of function Beeper. This function displays a message. void Beeper(void) { cout << "I am now inside the function Beeper.\a\a\a\n"; }   // Definition of function Beep. This function calls the function Beeper.   void Beep(void) { cout << "I am now inside the function Beep.\a"; Beeper(); // Call function Beeper cout << "Now I am back in Beep.\a"; }   void main(void) { cout << "I am starting in function main.\n"; Beep(); // Call function Beep cout << "Back in function main again.\n" }

Programming technique exercise Question 1). Write a complete C++ program that helps the teacher to calculate the result of students in the test of Programming Technique. The program should perform the following tasks: • Write a function named getinput. This is a non-returning function. It takes the score of question 1, score of question 2, and score of question 3 as input parameters. the function should ask the user to enter the score (per 100) for each question. It sends all the values entered by the user in (c) back to the calling module through the use of reference parameters. • Write a function named dispTier. This is a non-returning function. It takes the total marks as an input parameter. The function should display the tier based on the conditions. Tier 3 = below 40%, tier 2 = below75%, tier 1=75% and above • Write a function named calcAverage. I It takes the number of students and total marks as input parameters.
