3. Fundamentals of Strings and Characters
Building blocks of programs
Every program is a sequence of meaningfully grouped characters
Character constant
An int value represented as a character in single quotes
'z' represents the integer value of z
Strings
Strings are arrays of characters
String is a pointer to first character
Value of string is the address of first character
String definitions
char color[] = "blue";
char *colorPtr = "blue";
Inputting strings
scanf("%s", word);
Remember that strings represented as character arrays end with '\0‘
