Variables

Variable represents named storage location, whose values can be manipulated during program run. variables are called symbolic variables because they are named.

There are two values associated with a symbolic variable:

Rvalue, its data value stored at some location in the memory.

Lvalue, its location value that is the address in the memory at which its data value is stored.

rvalue of A = 10

lvalue of A = 1052

rvalue of C = 25

lvalue of C = 1055
