Hi C++ gurus, please help!!
I have been having problems with dtors (being new to c++).
Here's a list of my problems, code segment and error returned.
1. Defined 2 classes in my header file
2. Included the .h file in my main and other function
(2 diff files)
3. Goes thro' cfront but is flagged down by linker ( CC -o ..)
Apparently the ctors were left lying around and when encountered
again (in the main pgm where the .h file is included again), complained.
The dtors did not get around to do their job. Can you look at this
segment and give me an idea as to how my dtors should look?
I am not completely sure of how my dtors should look. I tried these
two basic dtors and they don't seem to do anything.
1. use standard ~class_name(); without any arguments
( I knew this woludn't do much )
2. delete all objects serving as arguments to the class.
Can someone give me guidelines as to how my dtors should look?
please e-mail your appreciated suggestions to my address below.
thanks in advance, sridhar sridhar@ksuvax1.cis.ksu.edu
