A variable definition has its meaning at the time of compilation only, the compiler needs actual variable definition at the time of linking the program. A variable declaration is useful when you are using multiple files and you define your variable in one of the files which will be available at the time of linking of the program.

You will use the keyword extern to declare a variable at any place. Though you can declare a variable multiple times in your C program, it can be defined only once in a file, a function, or a block of code. The same concept applies on function declaration where you provide a function name at the time of its declaration and its actual definition can be given anywhere else. An lvalue may appear as either the left-hand or right-hand side of an assignment. An rvalue is an expression that cannot have a value assigned to it which means an rvalue may appear on the right-hand side but not on the left-hand side of an assignment.

Variables are lvalues and so they may appear on the left-hand side of an assignment. Numeric literals are rvalues and so they may not be assigned and cannot appear on the left-hand side. Toggle navigation.
