CSE 232: C++Programming in Visual Studio

Graphical Development Environments for C++ Eclipse

Widely available open-source debugging environment

Available on Windows, Linux, others Designed to use g++ and other existing open-source tools

Unfortunately not working on Urbauer Windows machines

Visual Studio Specific to Windows but still widely used

Excellent multi-threaded debugger, eases Windows development

Uses Visual C++ (and other tools for other languages)

Works fine on Urbauer machines, so well use this for now

Overview of Todays Session Start Visual Studio and create a C++ project

Look at the code and files it generated automatically

Create a simple hello, world! program

Build, fix, and repeat until the program compiles

Set breakpoints and step over lines of the program

Look at the programs output in the debug terminal Stepping off the end of the main program

Into the crtexe.c file from which the main function is called

Try printing out the programs name (in argv[0])

Look at different syntaxes for the main function How those different forms treat argc and argv, for example

A Couple More Things to Try

CSE 232: C++ Programming in Visual Studio

A Couple More Things to Try

Exercise: what do you see when you have theprogram print out argv[0]? Why does it print that?

What is it printing vs. what we saw in previous sessions?

Exercise: change syntax of the main function tomatch what we used in earlier sessions What does printing argv[0] show now?

What if you print out the other program arguments?
