Thread: Questions on some definitions

Hello,
I wanted to know if anyone could help me out with some definitions i can't figure out in C programming.

1. What is right justification with respect to printf()

2. what is the difference between pre-test and post-test in relations to a loop.

3. What is an abstract data type in C.

4. What is a module in C.
and
5. What is the difference between a syntax error and a logic error.

Thank you so much for your time.

Jay

sounds like we got homework again, i'll tell ya A and a hint to B.
A) right justification is like when you do:

Code:

printf("%20s",string);

it will print the string or whatever the datatype is 20 characters and justify to the left, so if the string is 15 characters it will print 5 spaces then the string

B) A pre test is what a while statement is, ie

Code:

counter=5;
while(counter<5)
  counter++;

and a post test is what a do while statement is, ie

Code:

counter=5;
do{
  counter++
} while(counter<5);

Basically a pretest will test the condition before it does the loop where as a post test will complete one-cycle of the loop and test the condition. To understand compile and run both the above pieces of code and print the value of counter.

Thank you Bull for the help. By the way this isn't for homework. I have an exam tomorrow and my professor told us to learn these definitions. The exam is not from our book, it's from a different book so i can't seem to find all the info and i've tried searching the web for these definitions but can't seem to find them. Thanks once again.
