array of char*
-
Hi there! I need an array of strings of
char *type and I am not clear about how to free up memory after use. The code below does not work.char \* ptr\_p\_c\[3\]; ptr\_p\_c\[0\] = new char; strcpy (ptr\_p\_c\[0\], "hi there"); ptr\_p\_c\[1\] = new char; strcpy (ptr\_p\_c\[1\], "whatever"); delete ptr\_p\_c;I know I shouldn't be using this type for strings and all this. Believe me, I've tried repeatedly to convince my customer this is not the right way to do things, but unfortunately it is not my decission... Thanks a lot.

If you are a professional, then MAKE IT your decision. if it takes less time to develop, less time to debug, make the code more secure and readable, than you need to do it the right way. anyway,you should delete each item in the ptr_p_c array. good luck.
Watched code never compiles.

Why does the customer need to know how you are implementing a small piece of code? If they understand that level of detail then why do they need you?
Just say 'NO' to evaluated arguments for diadic functions! Ash

I know dumb customers. I also know dumber customers. But this is the dumbest customer.

You know dumb customers. I know dumb customers. He knows dumb customers. Hey Superman, your customers. Hey Superman, YOUR customers are just not that dumb. :-D

A good reason to dislike them. :)

Well, you already know that avoiding
std::stringis just plain silly so I don't bother you more:char * ptr_p_c[2];
ptr_p_c[0] = new char[sizeof("hi there")];
strcpy (ptr_p_c[0], "hi there");
ptr_p_c[1] = new char[sizeof("whatever")];
strcpy (ptr_p_c[1], "whatever");
delete ptr_p_c[0];
delete ptr_p_c[1];If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

[My articles]It looks like your sample is an example of why std:::string should be used: The null terminator will overflow the char[] buffers you allocated by one byte.

You're wrong. Hint: I didn't use
strlen. :)If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.
