CSCI 235 — Java to C

Get a file

• Mash the link and download a Gzipped NetBeans project.
• Save the project in your home directory.
• If java is installed (unlikely), we’ll try to out.
• Otherwise, use download the blastoff class and save it in the desktop.

Java to C tranformation

You’ll have to pay attention.

• Go to the command line and start nano.
• Get rid of the class stuff. Leave only the main method.
• Add an include for stdio.h and stdlib.h .
• Turn the main method into a main function header.
• The assignment to i is OK.
• We will use atoi to convert the argument, even it is doesn’t do any error checking.
• Be sure to use argv[1]!
• The if needs no changes.
• You can delete the try-catch.
• The for header is fine.
• Replace system.out.printf with a simple printf.
• Replace system.out.println with puts.
• Be sure to return 0.

Compiling

Follow along for this one.

You really do need a Randy Bryant approved Makefile like this.

CFLAGS = -std=c99 -Wpedantic -Og -g

all:       blastoff

blastoff:  blastoff.c

clean:
	rm blastoff *.o *~

Watch out for the tabs!

C++ program

Although every C program can make it through the C++ compiler, C++ has a unique style of I/O.
