Do you mean a c-style string?
Code:
char s[] = "some string";
std::cout << s << std::endl;
Note: a cstring is terminated by '\0' so that it can be used in string functions like strcmp. you can have a char array as well.
Code:
char char_array[] = { 'h', 'e', 'l', 'l', 'o' };
// if you tried to output that, you may wind up with trailing junk characters.
std::cout << char_array << std::endl;
Code:
char char_array[] = { 'h', 'e', 'l', 'l', 'o', '\0' };
std::cout << char_array << std::endl;
// good to go
