Copy the string from const char* To char[500];

while (p[i] && i < sizeof(q) - 1 )
q[i++] = p[i];

Yes I know that it was simple but you are suggesting to the OP that each time he has to copy a string, he should use this code. Honnestly, I really don't think it is a good idea because it makes the code much more difficult to understand (suppose that you repeat that code in a lot of places in your code X| ). And apparently, that's what the OP is going to do instead of using one of the "built in" mechanism.

Nope, I would suggest him to use the library functions actually. I posted the code just to show how the task could be accomplished without using such functions (as a side note to other answers).

I agree, because library functions are more general.

I disagree. OP should have at least a rough idea on what happens behind the curtains of the library functions. Repeating the code is a very bad practice that I would never suggest. I suppose that showing a piece of code is not a boost to 'inline' code instead of properly 'wrap the code with a function and then call it everywhere it is needed'.

I'm really not so clever to guess OP intentions. Anyway I would suggest him to use library functions (that anyway are not, in my opinion, a built-in mechanism...). :)

Hi all can you help? part of my code i need to do this
const char * p= "ddddd";
char q[500];I want to copy the sting in p to q[]?
Well, you've not had a C++ answer using STL yet...so, just because:
// needs #include
const char * p= "ddddd";
char q[500];std::copy(p, p+strlen(p), q);
Of course, it is less efficient than the pure C answers, as it iterates through p twice.
Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

That's hybrid!
// needs a different #include!
const char * p= "ddddd";
char q[500];std::string s(p);
s += '\0';
s.copy(q, s.length());(I know, that's, well..., ugly! :rolleyes: ) :-D

Well, if I'd known you were bringing strings, I'd've used this:
const std::string p = "ddddd";
std::string q;
q=p;Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p
