Can I convert a string to an array of chars in c++?

Question

I want to do things like checking for spaces or reversing a string, which I can do if a string can be made into an array. Can someone help me out?

I know char foo[]="Hello"; will make an array.

But is it possible to do something like this?
cin>>my_string;
char foo[]=my_string.tochar();

Answer 1

Simplest way I can think of doing it is:

string temp = "cat"; char tab2[1024]; strcpy(tab2, temp.c_str());

For safety, you might prefer:

string temp = "cat"; char tab2[1024]; strncpy(tab2, temp.c_str(), sizeof(tab2)); tab2[sizeof(tab2) - 1] = 0;

or could be in this fashion:

string temp = "cat"; char * tab2 = new char [temp.length()+1]; strcpy (tab2, temp.c_str());

Thank you. I think I'll use the third one.

Or if I make sure that temp is the expected size, I can use the first one.

Thank you very much. I understood now.
