44 Introduction to C++ Programming and Graphics

Postscript is a computer language like C++. A postscript printer un-
derstands this language and translates it into pen calls that draw images and
high-quality fonts.

Software distributions

Suppose that a project namedrizogaloand another project namedtra-
hanasare defined in the makefile. To execute both, we define in the same
makefile the task:

all:

rizogalo

trahanas

and issue the command:

make all

The tasksinstallandclean, defining software installation and distilla-
tion procedures, are common in makefiles accompanying software distributions.
To install software, we type

make install

To remove unneeded object files, we type

make clean

Problems

2.7.1.Define in a makefile a project calledcleanthat removes all.oobject files
from the current directory using the Unixrmcommand (see Appendix A.)

2.7.2.Define in a makefile a project that generates the executable of a C++
program and then runs the executable.

2.8 Simplecodes

We are in a position to write, compile, and execute a simple C++ code.

The following program declares, evaluates, and prints an integer:

#include <iostream>

using namespace std;
