Very simple C program ( running total) [solved]

Homework Statement

Question is:

Given that two int variables, total and amount , have been declared, write a sequence of statements that:
initializes total to 0
reads three values into amount , one at a time.

After each value is read into amount , it is added to the value in total (that is, total is incremented by the value in amount ).

Homework Equations

The Attempt at a Solution

My answer is this:

total = 0;
amount = 0;
do{
++amount;
total += amount;
}while (amount < 3);

Their response is:
Remarks:
⇒ Did you read in all three values?
Remarks:
⇒ At Execution

What did I do wrong?

Apparently I was just supposed to copy paste it three times with scanf("%i",&amount) instead of amount++

It's a good idea to put [ code] and [ /code] tags (without leading spaces) around your code. I've done it below, and indented your code to make it more readable.

total = 0;
amount = 0;
do
{
   ++amount;
   total  +=  amount;
} while (amount < 3);

In answer to the questions above, no, you didn't read in any of the three values. The values should have been entered at program run time.

Yes, you should use some input function, such as scanf, to do input.
