Thread: sentinel terminated loop/avg calculation

I am working on this program and I need to add two things to it, first I need the program to accept many students names and scores (not just one) and add a sentinel terminated loop which the loop terminates when the students first name is "light" and last name is "truth". Also, on the student average calculation, I need to be able to drop the lowest score and count the highest score twice for example if the score were: 90 80 70 70 80, I would drop one of the 70's and count the 90 twice. I am really confused, any help would be greatly appreciated!

Code:

#include <iostream.h>
#include <iomanip.h>

int main()

{
	char firstName[25];
	char lastName[25];
                float score[5];

	char grade;
	float avg=0.0;
                float totScore=0.0;
	int x=0;
	int y=0;

	cout << "Enter student's first name, last name, and five scores:";
	cin >> firstName >> lastName;

	for (x=0; x<5; x++)
	{
		cin >> score[x];
     
			
	}
       
    
	
	for (y=0; y<5; y++)


     totScore += score[y];
     avg = totScore/5;
	{
	
		if (avg >= 92.0)
			grade='A';
		 else if (avg >= 83.0)
			grade='B';
		 else if (avg >= 74.0)
			grade='C';
		 else if (avg >= 65.0)
			grade='D';
		else
		    grade='F';
         
		
        
        		
		}

           

	cout << lastName<< " , " << firstName << " " << setw(6) << setprecision(2) 
		<< "Average:" << avg << " " 
		                                  << "Grade:" << grade << endl;

		return (0);

}

First,

use here

Code:

#include <iostream>
#include <iomanip>

using namespace std;

instead of

Code:

#include <iostream.h>
#include <iomanip.h>

is a start..

Also use the string class instead of an array of chars- it will make your life much easier.


Make changes and repost.
Mr. C.

Okay I put in the strings and tried to declare a struct, but I am getting two errors. I have added comments in the program.

Code:

#include <iostream>
#include <iomanip>

using namespace std;

int main()

struct StudentRec//wouldn't I have to declare a struct declaration?
{//here I get unexpected end of file error and syntax error missing ';' before '<class-head>'
	string firstName;
	string lastName;
    string score;

	char grade;
	float avg=0.0;
    float totScore=0.0;
	int x=0;
	int y=0;

	cout << "Enter student's first name, last name, and 5 scores:";
	cin >> firstName >> lastName;
	

	for (x=0; x<5; x++)
	{
		cin >> score[x];
     
			
	}
       
    
	
	for (y=0; y<5; y++)


     totScore += score[y];
     avg = totScore/5;
	{
	
		if (avg >= 92.0)
			grade='A';
		 else if (avg >= 83.0)
			grade='B';
		 else if (avg >= 74.0)
			grade='C';
		 else if (avg >= 65.0)
			grade='D';
		else
		    grade='F';
         
		
        
        		
		}

           

	cout << lastName<< " , " << firstName << " " << setw(6) << setprecision(2) 
		<< "Average:" << avg << " " 
		                                  << "Grade:" << grade << endl;

		return (0);

}

Okay, I reread my instructions and finally figured this program out. I had to make several changes, well actually rewrite the entire thing. I was way off base!
