Question

Write a program to read in a collection of exam scores ranging in value from 0 to 100. Your program should display the category of each score. It should also count and display the number of outstanding scores (90 to 100), the number of satisfactory scores (60 to 89), and the number of unsatisfactory scores (0 to 59).  Your program should display the average score at the end of the run. Your program should ensure that each score is valid (in the range 0 to 100).

Explanation / Answer

#include <fstream>

#include <iostream>

#include <conio.h>

using namespace std;

#define in_file "examdata.txt"

int main()

{

ifstream ins;

int marks;

int numofOutstandingScore=0, numOfSatisScore=0, numOfUnsatisfacScore=0,totalNumScores=0,numinvalidSore=0;

int avg,total=0;

char next_char;

ins.open(in_file);

cout<<"Marks "<<"Remarks"<<endl;

while (!ins.eof())   

{

ins >> marks;   

ins.get(next_char); // echo print input to screen

cout<<marks<<" ";

//price range check.

totalNumScores++;

if(marks>100||marks<0)

{

cout<<"This marks range is invalid"<<endl;

numinvalidSore++;

continue;

}

else if(marks>=90)

{

cout<<"outstanding scores";

numofOutstandingScore++;

}

else if(marks>=60)

{

cout<<"satisfactory scores";

numOfSatisScore++;

}

else

{

cout<<"unsatisfactory scores";

numOfUnsatisfacScore++;

}

total+=marks;

cout<<endl;

}

avg = total/(totalNumScores-numinvalidSore);

//summary Table

cout<<"SUMMARY TABLE:"<<endl;

cout<<"total number of outstanding scores = "<<numofOutstandingScore<<endl;

cout<<"total number of satisfactory scores "<<numOfSatisScore<<endl;

cout<<"total number of unsatisfactory score "<<numOfUnsatisfacScore<<endl;

cout<<"total number of Invalid score "<<numinvalidSore<<endl;

cout<<"Total number of exam scores"<<totalNumScores<<endl;

cout<<"Avarage score of a student :"<<avg<<endl;
