how to increase the size of an array

[iluv41]

I have an array that i need to increase the size of depending on the object being used.

How would I increase the size of this array if I needed to?

// this is the array that's created each time my function is called
char * temp = new char[max];  //max is an int

The easiest method is to use std::vector<char> (or std::string) rather than plain array.

But can it be a char array

[Darkmaster]

you can create an array for the object and set the array's size when creating it.
but you can not change it's size during runtime.

I would just use a vector for that task.

"need"?

char * temp = new char[max];

char * foo = new char[max+more] {};
std::copy( temp, temp+max, foo );
delete [] temp;
temp =  foo;
foo = nullptr;
