Posted by diegoeskryptic [send private reply] at March 28, 2002, 01:06:10 PM For my assignment... my teacher told me to complete a program by adding function declarations, function implementations and variable definitions in the main program. I need to know exactly what are these three things... thanx

function declaration: something that tells the compiler of the existence of a function, the code of which may or may not be along side the declaration
function implementation: the actual code which makes up the function
variable definitions: something that tells the compiler that a certain "thing" is a variable, and that it should allocate memory for the variable

Posted by CodeRed [send private reply] at March 28, 2002, 09:59:01 PM A function declaration is also called a prototype. They goe below your includes and above the main function. They consist of the return type, the function name, and the parameter types and (optionally) names. A function implementation is simply writing the function. Variable definitions are simply declaring variables, you don't get much easier than that...
