c程序代做

1.6 – The Preprocessor

All exercises in this Level must be coded exclusively in C syntax (no

<iostream>, cout, cin, classes, etc.)

Exercise 1

Write a C-program that contains two print macro calls. The first prints the variable a, the

second prints the variables a and b. Printing happens by the use of the PRINT1 and

PRINT2 macros that accept arguments. These macros must be defined in an include-file.

The variables a and b gets their value in the function main().

Name the program “Macro.c” and the include-file “Defs.h”. Don’t forget to implement

the mechanism to avoid multiple inclusion of the header file.

Exercise 2

Create the two macros MAX2(x,y) and MAX3(x,y,z). These macros must return the

maximum value of the given arguments. Let the macro MAX3 make use of the macro

MAX2. Add these macros to the file “Defs.h”.

1.7 – Pointers and Arrays

Exercise 1

Try to create a function Swap(). This function must exchange the value of two variables.

For example: if i=123 and j=456, then i=456
