You got your loop wrong...should be something like this
you want to have the user enter two integers and return the sum from the first integer, and every integer in between the second integer entered
int x,y; // First and second integer enteredint sum = 0; // Make sure to set sum to 0for( int i = x; i < y+1; i++ ) sum += i;
The problem your having first off is that sum contains garbage because you never initialized it to 0. Most likely why you getting those weird values.
Second error is the use of "count" in your code. Each iteration your setting it to 0, thus basically adding 0 each loop to x which is always going to be the first integer entered....so sum is going to equal whatever garbage value + x for each loop iteration.
Third error is you for condition, it should be i < y+1 and not i < y as this would cause premature exit of the loop without adding in the value of y, and we want up/to and including y
Let me give ya an example of test values using my loop. Here we go
When we come to the for loop x and y will hold the integer values
(say 3,5 ..keep it short
) and sum will have been set to 0, so that it records a valid sum.
Once we enter the for loop:
1st Iteration -
the variable i gets initialized to x''s value ( so i == 3 ) and
i will be less then 6 so the condition holds
sum will become sum = 0 + 3 ( writing it like sum = sum + i )
sum will equal 3 at the end of this iteration
i will be incremented to now equal 4
2nd iteration -
i will be less then 6
sum will become sum = 3 + 4
sum will equal 7 now
i will be incremented to 5
3rd iteration -
i will be less hten 6
sum will become sum = 7 + 5
sum will equal 12 now
iwill be incremented to 6
4th iteration -
i is NOT less then 6 and we fall out of the loop
This might be a bit long I apologize, but I hope it helps ya understand loops a bit better

Anyways, please help...
or else it will contain garbage. You don''t have to do this with x or y because their values are reassigned with user input.
