tutor is needed here plz.

Expand Post »
Hello.. can someone teach me how to do this program.

This is the question.

1. An organization has aprox. $1000 available to be allocated in small amount to approved charities. Write a program that will read several amounts and ((report as soon as over $1000 has been allocated. << NOW this is the part that i didn't know how to do!))

2. Display the number of donations required to exceed $1000.
For example in the output ATTACHED this message should be displayed: "4 donations were made" << this also didn't know how to do it.

Please note that i didn't take arrays yet.. so i'm not suppose to use them.. i only took loops, if-else, switch, and functions.

This is what i know.. so far:
C++ Syntax (Toggle Plain Text)
  1. # include <iostream>
  2. using namespace std;
  3.  
  4. int main ()
  5. {
  6. 	int x,i=0;
  7.  
  8. 	do
  9. 	{
  10.  
  11. 		cout<<"Please enter an amount: ";
  12. 		cin>>x;
  13.  
  14. 	i++;
  15.  
  16. 	}while(x<=1000);
  17.  
  18. return 0;
  19. }

Re: tutor is needed here plz.

what your code currently does is, it stops when any single amount is greater than 1000. you need to come up with a way to "keep track" of what has already been allocated.

Re: tutor is needed here plz.

do you know the concept of a counter variable? perhaps it will help you.

using a single variable x, you can only store the current value. you need to be able to store a cummulative values (which will be stored in your counter).

hope that helps

Re: tutor is needed here plz.

no, it's definitely not the right way. for a start, the counter should form your loop's condition statement (hint 1). furthermore, even if you were using your counter as part of the condition it would only check the number of allocations you have done, not the actual value allocated (hint 2).

have a think for a while, don't just reply in hope of getting code.

Re: tutor is needed here plz.

I get the impression you aren't really trying here, produce some updated code with what you are trying...

maybe then I can give more assisstance.

Re: tutor is needed here plz.

hey fadia, i think this wil work 4 ur need. 
#include <iostream>

using namespace std;

int main ()
{
int x=0,Donate=0,i=0,l=1;
while(l==1)
{
if(Donate<1000)
{
cout<<"Please enter amount 4 DoantionNo: "<<i+1<<" ";
cin>>x;
Donate=Donate+x;
i++;
}
else
{
l=0;
cout<<"$"<<(Donate-1000)<<" over $1000 has been allocated in "<<i+1<<" number of donations";
}
}
cin>>x;
return 0;
}

Re: tutor is needed here plz.

auhuman, Though you have made 4 posts, You have been here for about 4 month's i believe, So It is of the impression that you must be knowing about the workings of this forum.
Basic Rule On Homework Help
Though your motive was to help Fadia out, It should have been done by telling him what he had to accomplish and how can he do so , But, not by giving away code.

Secondly, In the code you have given, I think that the variable in the while loop l can be completely avoided, Or Should have been replaced by a type bool
