How on gods green earth are we meant to answer that?

My guess is that you have a bug in your program, possibly an infinite loop. Windows is not getting a timely response from your program, so tells you it has stopped working.

yeah there is a loop in input and output files, OK then how to limit the loop ?

here is my program .

// a program that reads a list of students marks from an input file and calculate
// average total marks and grades in an output file
#include<iostream>
#include<fstream>
#include<string>
#include<iomanip>

using namespace std;

int main()
{

float ID[10],homew[10],lap[10],final[10],total[10];
string grade[10];
int x=0, studentNum = 0; // initial value zero

float avgTotal;// total marks average
string avgGrade;// class average grade

ifstream infile;
ofstream outfile;
string filename;
//****************************************************************************//
cout << "Enter the file name(info.txt) please:" << endl;
cin >> filename;

infile.open(filename.c_str());//open input file

if (!infile)
{
cout << "Can't open input file " << endl; // error message if input file does not exist
return 1;

}

while (infile)
{
x++;
studentNum++;
infile >>ID[x]>>homew[x]>>lap[x]>>final[x];

}

//****************************************************************************//

outfile.open("results.dat");// open output file
if (!outfile)
{
cout << "Can't open the output file" << endl;//error message if output file does not exist
return 2;

}

while (outfile)
{
x++;
studentNum++;

total[x] = homew[x] + lap[x] + final[x];
if (total[x]<0 && total[x]>100)
cout << "total mark is not counted" << endl;

outfile << ID[x] << setw(6) << total[x] << setw(6) << grade[x];

if (total[x]>=95&&total[x]<=100)
grade[x]="A";
else if (total[x]>=90&&total[x]<=95)
grade[x]= "A-";
else if (total[x]>=85&&total[x]<=89)
grade[x]= "B+";
else if (total[x]>=80&&total[x]<=84)
grade[x]="B";
else if (total[x]>=75&&total[x]<=79)
grade[x]="B-";
else if (total[x]>=70&&total[x]<=74)
grade[x]="C+";
else if (total[x]>=65&&total[x]<=69)
grade[x]="C";
else if (total[x]>=60&&total[x]<=64)
grade[x]="C-";
else if (total[x]>=55&&total[x]<=59)
grade[x]="D";
else if (total[x]<=55)
grade[x]="F";


avgTotal = total[studentNum]/studentNum; // class average of total marks
outfile << "The class average total mark and grade is: " << avgTotal << endl;


if ( avgTotal >= 80)
outfile << " High average" << endl;
else
outfile << "Normal average" << endl;


}//end of file


infile.close();// close input file
outfile.close();// close output file

system("pause");
return 0;
}

Try using an if statement at the bottom in the int main() which will terminate the whole loop with a break if a certain value exceeds the number you want.
