1. 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

2. CSE 232: C++ Programming in Visual Studio 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

33. CSE 232: C++ Programming in Visual Studio 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?
