operational definition of a manipulated variable
Declaring a variable or function reserves an entry in a symbol table for that function or variable (entries in a symbol table eventually become memory addresses during linkage). Defining a variable or function actually specifies the value to be stored in the memory location specified and/or the code that should be compiled. Examples: Declaration: int foo(); // Declares a function. int bar; // Declares a variable. Definition: int foo() { printf("Hello World"); } bar = 5; Declaration and definition: int bar = 5;
