Graphical Development Environments for C++

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 we’ll use this for now


Overview of Today’s 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 program’s 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 program’s name (in argv[0])• Look at different syntaxes for the main function

– How those different forms treat argc and argv, for example


Starting Visual Studio


Choosing Visual C++


Click on Create Project


Choose Win32


Fill in Project Name


Click Finish to Create the Project …


… Which May Take it a While to Do


Visual Studio Generated Several Files


Provided StdAFX Header File


Provided StdAFX Source File


Provided Readme.txt File


Have the Program Print Out Hello, World


Build the Program


What do the Errors Tell Us We Missed?


Corrected Program


Build Again


Successful Compilation


Setting a New Breakpoint


Breakpoint in the main Function


Start Debugging


Debugger Stops at the Breakpoint


Stepping over the First Line


After Stepping Over Once


Program Output in Terminal Window


Stepping Over a Second Time


At The End of the main Function


What if we Stepped Over Once More?


In the crtexe.c file (calls different Mains)


F5 or Continue to Complete the Run


All Done (can close crtexe.c now)


A Couple More Things to Try• Exercise: what do you see when you have the

program 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 to match what we used in earlier sessions – What does printing argv[0] show now?– What if you print out the other program arguments?
