How to print this kind of result with arrow operator

[jaden5165]

pscobject->add_v3_signal($1, tmp);

May I know how can i print the result perform by this code?After go thru this code i want to print what is the result will be returned.How can I write the print out way.

If in c:
How can I use printf to print it

If in c++:
how to use cout to print it?

What is the type of the result?

[jaden5165]

EXTERN _pscmain* pscobject; pscobject = new _pscmain;


I found these two line.But i duno how can i know what is type?

[vlad from moscow]

What is the type of expression pscobject->add_v3_signal($1, tmp);
that you are going to print?

[jaden5165]

Hi vlad

The return value from the subroutine add_v3_signal($1,tmp) will be
return (_V3Signals[_num_v3_signals - 1])

from my reply above the type you mean is not pscobject = new _pscmain; which mean hv dynamic memory that point to _pscmain type.Do correct me if i am wrong.

Can teach me how to print ?

you need the return type of _pscmain, or, rather, what type is (_V3Signals[_num_v3_signals - 1])

[jaden5165]

hi hansaaa

_v3signal **_V3Signals;



does the bold words consider as type of _V3Signals?

[hansaaa]

well, it seems to be an instance(or, rather, a pointer) of a _v3signal, whatever that is? Do you know what it is and how to print it?

What are you expecting as a sample output of this?

[jaden5165]

I duno how to print it.I just dunwan to print the address store in _V3Signals.I want the content pointed by _V3Signals.How can I print it?seriously i duno what is the content will be either integer or string.

[hansaaa]

well if you don't really know what it is, how can you print it. where did you get it from?

[jaden5165]

I am new hire.Company want me to understand codes.
if for simple code like
int *ptr char *pptr
i know we can use printf("%d,%s",ptr,pptr)


but when come to _v3signal **_V3Signals; the type in a class alrready.How can I know what is the content to keep inside.

I think you need to learn more about programming before knowing how to do this...

[jaden5165]

Yup.thats the only way :(

[hansaaa]

do you know object-orientation (object-oriented programming/modeling). that could help here.

[jaden5165]

Ya I know.But mostly the basic one.Will put more effort to learn.Thx
