C-Style Strings

Character Arrays

Arrays of the char type. They are used to represent text in C-style, ending with a special null terminator \0.

DECLARATION & NULL TERMINATOR

char name[6] = "Alice"; // Auto adds \0
char city[] = {'N', 'Y', '\0'}; // Manual \0

cout << sizeof(name); // 6 (including \0)

cin vs cin.get()

cin stops at spaces. Use cin.get() or getline() for strings with spaces.

BUFFER OVERFLOW

Writing more characters than the array size can overwrite adjacent memory.

Common Functions (cstring)

strlen()strcpy()strcat()strcmp()
