Thread: I need help plzz :(

We have 20 Students from different levels (4290**** , 4280**** , 4270**** , 4260****) Every ID will start with one of those numbers .. (The ID cosist of 8 digits )
And their Grades in 1 subject..

It is supposed to print :

1- Students ID and their Grades.

2- Student ID that got the highest grade and the lowest grade and their and the ID Second two numbers starting from the left for the two students.

3- The number of students got grades equal to Average or higher.

4- The number of students got grades smaller than the Average.

5- The number os Students from each Level .

This is the program I wrote :

Code:

#include <iostream>
#include <conio>


void main()
{
int numberOfStudents [20] ;
int score[100];
char grade;
int ID ;
int i , j ;

for( i=0 ; i<20 ;i++)
{
    cout << "Enter Student "  << (i+1) << "  ID " ;
   cin>> ID;
   cout<< "Enter the score ";
   cin>>score[j];

for( j=0;j<20;j++)
    {
    if(score[j]>=90)
        grade='A';
    else if(score[j]>=80)
        grade='B';
    else if (score[j]>=70)
        grade='C';
    else if (score[j]>=60)
        grade='D';
    else
        grade='F';
     }
  }
    cout<<"Student "<<(i+1)<<" score is = "<<(score[j])
    <<" and grade assigned is "<<grade<<endl;

  getch ();
}

I don't know how to complete it .. ><
Any Help would be Gratefully Appreciated !!

Where are you suppose to get the grades from? are you inputting them from a file?

Do you have AIM or anything to chat. I have some extra time right now if you need help

*to calculate the average:
in the first for loop sum+=score[i];

then in the end of the program

float Avg= sum/20;
cout<<"average = "<<Avg;

*for the lowest and highest:
declared a new variables
low=score[0];
high=score[0];

then make another for loop

Code:

for(int n=1; n<20; n++)
{
      if ( score[n]>low) 
      low=score[n];
      if (score[n]<high)
      high=score[n];
}

i hope it is will help u... and if u have any question u are more than welcome...

ladybird we want people to try to solve the problem on their own. We do not want to simply tell them what to do, they will never learn this way. And I'm assuming this is homework so we are not here to do homework for people.

and if nothing else explain why he needs to be making these changes so he can understand on a logical level how they work
