(C++) char

 

char is a keyword for a (single-)character data type to store a character literal. std::string can be used to store a collection of char.

int main() {   const char c = 'x'; }

 

Prefer plain char over signed char and unsigned char [1]. Use std::string rather than zero-terminated arrays of chars [2].
