NEED Quick Standard Solution!

Simple question,
Is there a way to convert a string
to char* or char [255]
either will work for me.
I did a google search but to much junk to sort
through came up and nothing that really helped!

All replies are appreicated, and thanks in advance!

Ex.

Code:

string mystring = "Hello World!";

converted to : (but the below does not work)

Code:

char * mychars = mystring;

or

char mychars[255] = mystring;

I even went as far as to use a for loop to copy each individual
character from the string, but that didnt always prove successful
i need a surefire way!

I also tried strcpy() but it only seems to copy
char* to char* or string to string, not string to char*

Code:

for(int i = 0; i < smaller_of_the_two_sizes; i++)
    mychars[i] == mystring[i];
//don't forget to throw the null terminator at the end of mychars.

OR

strcpy(mychars, mystring.c_str());

A couple questions? Do you need to be able to modify it?
If no:

Code:

mystring.c_str();

Will return a const char *

If you need to be able to modify it:

Code:

char *ptr = new char [mystring.length()+1];
// copy from the string and append a null character
// do whatever
delete[] ptr;

No ive already done the modifying to the string,
then the char will remain const!

ah maybe thats why the forloop i did before didnt work
i forgot the '\0' ok thanks, ill replay back if it worked!

Thank You Both Of You Guys!

c_str(), allowed my code to compile with no errors
or warnings, im unable to test if it works completely
yet for the code is not complete but it should!
