need some hand

WAP a C++ program using Structures to calculate the total and average of scores of a selected student. The program should prompt the student to input the stu_id. This stu_id is checked against the stu-ids’ and make sure it really exists. Calculate the total and average, if the scores in assignment1 (out of 10 marks), assignment2 (out of 10 marks), mid-term score (out of 30 marks), and final score (out of 50 marks) are given.

I'm bored, so I'll do your homework for you as a sketch! ^^

Student stdnt;

cout << "Please enter next student data: ";

cout << "ID: ";
cin >> stdnt.iID;

cout << "Name: ";
cin >> stdnt.strName;

cout << "Score: ";
cin >> stdnt.iScore;


This stu_id is checked against the stu-ids’ and make sure it really exists.

// ASSERTS

map <int, Student>::iterator it = mapStudent.find (stdnt.iID);
if (it == mapStudent.end())
  throw "Student ID not found!"
  
if (it->second.strName != stdnt.strName) 
  throw "Student ID found, but Name is wrong!"
  
if (stdnt.iScore < 0 && stdnt.iScore > 10) 
  throw "Score is not in range!"



Calculate the total and average, if the scores in assignment1 (out of 10 marks), assignment2 (out of 10 marks), mid-term score (out of 30 marks), and final score (out of 50 marks) are given.

map<string, double>  mapValues;

mapValues["assignment1"] =0;
mapValues["assignment2"] =0;
mapValues["assignment3"] =0;
mapValues["finalScore"]  =0;

for (map <int, Student>::iterator it = mapStudent.begin();
     it != mapStudent.end(); ++it) {
     
  if (it->second.iScore > 10)
    mapValues["assignment1"] ++;
  else if (it->second.iScore > 20)
    mapValues["assignment2"] ++;
  else if (it->second.iScore > 30)
    mapValues["assignment3"] ++;
  else if (it->second.iScore > 50)
    mapValues["finalScore"] ++;
  }



Output the result
