Please write a
program that computes the average of 3 exam scores of 3 students. It first asks
the user three exam scores for each student and then compute the average of
them.

The program should
have the following functions.

• 
  int getTestScore():
  
  This function is called by main function. It asks the user to enter the
  
  score of the exam. Once it gets a user input data, the function returns it
  
  to the main function. Input Validation: Please check if the entered score
  
  is between 0 and 100 inclusive (considered valid). If not, repeat asking
  
  to enter a valid score.
  




• 
  double
  
  calAverage(int, int, int, int, int):
  
  This function is called by main function. It calculates the average
  
  of 3 exam scores passed from main function in int data type. Once the function
  
  calculates the average, it returns it to main function in double data
  
  type.
  




• 
  void display(string,
  
  double): This function is called by main function and displays the
  
  student’s name and average exam score. The arguments are students’ name
  
  and the average exam score.
  




• 
  main(): Main
  
  function calls getTestScore() 3 times
  
  for each student to get the student’s 3 exam scores. And then, it
  
  calls calAverage() and display() to compute and displace the average of
  
  the 3 exam scores for that student.
  
  Please complete this process for 3 students using loop structure.
