Variables are identifiers associated with values. They are declared by writing the variable's type and name, and are optionally initialized in the same statement by assigning a value.
int myInt; /* Declaring an uninitialized variable called 'myInt', of type 'int' */ myInt = 35; // Initializing the variable int myInt = 35; // Declaring and initializing the variable at the same time
Multiple variables of the same type can be declared and initialized in one statement using comma as a delimiter.
int a, b; // Declaring multiple variable of the same type int a = 2, b = 3; // Declaring and initializing multiple variables of the same type
