Problem Statement: File Handling in C/C++
On the basis of the given scenario create a file Expenses.txt, Open the file and copy into another Expenses2.txt, Also show output on screen
A college has announced the total budget of 50,000Rs.for each game. Games are done four times in a year. Take expenses as an input from user.
Calculate the average expenses for a game:

1. If the expenses greater than 80% show as” Very Expensive”.
2. If the expenses are greater than 60% and less than 80% than show “Expensive ”
3. If the expenses are greater than 50% and less than 60% than show “Less Expensive ”
4. If the expenses are greater than 40% and less than 50% than show “Not Costly”.
5. If the expenses are less than 40% than show “Best”.

Code:

/* Program that create the File Expenses.txt, open the file and copy into 
another file Expenses2.txt, and show its output on the screen.*/

//Declaring header files
#include <iostream>
#include<fstream>
#include<conio.h>

Please help me in this program.My problem is that we are given that total budget of a game is 50000 but when the total expenses increases what should we do .....

There are at least two other threads about this exact homework problem on DaniWeb alone with countless others all over the internet.

well i guess ur asking if total expenses increases more than 50,000 ..?

In that case u can just check the variable total..
Which is been calculated in line 45 of your program .

Just put a condition checking for the expense to be less than or equal to 50000 . if condition is satisfied then proceed , or give a message and exit (or whatever needful is to be done) .

You calculate a percentage of 50,000. Then it either falls into one of five categories:

1. If the expenses greater than 80% show as” Very Expensive”.
2. If the expenses are greater than 60% and less than 80% than show “Expensive ”
3. If the expenses are greater than 50% and less than 60% than show “Less Expensive ”
4. If the expenses are greater than 40% and less than 50% than show “Not Costly”.
5. If the expenses are less than 40% than show “Best”.

Display output based on percentage. Even if you have an expense that is greater than 50,000, it will still qualify as case #1 in the above assignment criteria.
