Programming Exercise (50 points)1. Macros are available in most high-level programming languages.The body of a macro issimply used to replace a macro-call during the preprocessing stage.A macro introduces a"true inline" function that is normally more efficient than an"out-line" function. However,macros suffer from side-effects: unwanted, or unexpectedmodifications to variables.Macros should be used cautiously. The main purpose of the followingprograms is todemonstrate the differences between a function and a macro. Otherpurposes includedemonstrating the differences between different programmingenvironments, andlearning different ways of writing comments, formatted input andoutput, variabledeclaration and initialization, unary operation ++, macrodefinitions/calls, functiondefinitions/calls, if-then-else and loop structures, etc.Start by running each of the functions below and understand theirfunctionality.

Programming Exercise (50 points) Macros are available in most high-level programming languages. The body of a macro is simply used to replace a macro-call during the preprocessing stage. A macro introduces a "true inline" function that is normally more efficient than an "out-line" function. However, macros suffer from side-effects: unwanted, or unexpected modifications to variables. Macros should be used cautiously. The main purpose of the following programs is to demonstrate the differences between a function and a macro. Other purposes include demonstrating the differences between different programming environments, and learning different ways of writing comments, formatted input and output, variable declaration and initialization, unary operation ++, macro definitions/calls, function definitions/calls, if-then-else and loop structures, etc. 1.
