c - Strings - Data Type -

-

i have learned how handle data types except, strings. so, can me strings?

in declaration

char surnm[4] = {'p', 'i', 'n', 'e', '\0'};

there 5 initializers 4 elements in array surnm. array not contain string because did not included terminating zero. should write either

char surnm[5] = {'p', 'i', 'n', 'e', '\0'};

or

char surnm[] = {'p', 'i', 'n', 'e', '\0'};

or

char surnm[5] = { "pine" };

or

char surnm[5] = "pine";

or

char surnm[] = { "pine" };

or

char surnm[] = "pine";
