design and implement such a function and use it in a program called part3.c that allows someone to enter two real numbers and an epsilon value (also a real number) and reports if the two numbers are equal (+/- epsilon) or not.

If you were asked this question, how would you try to understand this question;

This is how I looked at it;

I'm asked for two real numbers and an epsilon number.

for example, 5 and 6. epsilon is then 2.

So when I compile my program, my program will do this: 5+2 and 5-2 which is 7 and 3

and 6+2 and 6-2 which is 8 and 4.

Then the result I would have program say would be: No, this is not equal.

Am I reading this right, please help

no, I don't think you are reading it correctly

Here is the logic a,b real numbers, e is some real number.

IF abs(a-b)<=e then YES

otherwise NO
