  1. INF160 IS Development Environments AUBG, COS dept Lecture 06 Title: Dev Env: Code::Blocks (Extract from Syllabus) Reference: www.codeblocks.org

  2. Lecture Contents: • Code::Blocks – introduction • Code::Blocks – functionality • Code::Blocks – configuration

  3. Code::Blocks – introduction • Code::Blocks: The open source, cross platform, free C, C++ and Fortran IDE. • Code::Blocks is a free C, C++ and Fortran IDE built to meet the most demanding needs of its users. • Built around a plugin framework, Code::Blocks can be extended with plugins. Any kind of functionality can be added by installing/coding a plugin. For instance, compiling and debugging functionality is already provided by plugins! • Code::Blocks 13.12 is here! (as of March 2014)

  4. Code::Blocks functionality • Code::Blocks includes: • Code Editor • Compiler • Debugger • Other SW tools

  5. Code::Blocks • How to Use?

  12. Code::Blocks how to use • To debug a C++ program: • If there are compiler errors, you should re-edit your source text in order to get successful compilation

  13. Code::Blocks how to use • To print program’s instructions: • File > Print… • Dialog box opens (check box line numbers?)

  14. Code::Blocks how to use • To close a project: • File > Close Project or • File > Close all Projects or • File > Close workspace

  15. Code::Blocks how to use • To open an existing project, .cbp file: • File > Open… • Open File dialog box gets opened • Navigate to the folder that contains the project .cbp file • Click Open button

  16. Code::Blocks • How to Configure?

  17. Code::Blocks how to configure • Note: The asterisk on the MyFirstSourceFile.cpp tab indicates that the changes made to the file have not been saved.

  18. Code::Blocks how to configure • NOTE: The font type and size used by default are Courier New and 14 point, respectively. If you want to change your editor window’s font type or size, click • Settings > Editor… > Editor settings tab, click Choose • When you are finished, click the OK button.

  19. Code::Blocks how to configure • NOTE: You can change the appearance (for example, the font, size, colors, and so on) of the Command Prompt window by right-clicking the window’s title bar and then clicking Properties. • When you are finished, click the Ok button to close the Properties window.

  20. Code::Blocks how to configure • NOTE:To display lines numbers in the editor window: • 1. Settings > Editor… > Editor settings tab, • 2. Section other options, select the Line Numbers check box.

  21. Code::Blocks how to configure • Settings > Environment… • Settings > Editor… • Settings > Compiler… • Settings > Debugger…

  22. Exercises/Tasks • Code::Blocks • Write a C++ program to: • display your personal data incl name, age, email address • Read two numeric data items • Compute and display result of their addition, subtraction, multiplication, division and modulus (in case of integer data).

  23. Exercises/Tasks • To demonstrate advantages of Code::Blocks • Back to MS Visual Studio • Write a C++ program to operate on arrays: #include <iostream> using namespace std; void main() { int m; // int m=10; cin>>m; const int m=10; int arr[m]; for(int i=0; i<m; i++) { arr[i]=i*10; cout << arr[i] << ‘ ‘; } }

  24. Exercises/Tasks • To demonstrate advantages of Code::Blocks • Back to Code::Blocks • Write a C++ program to operate on arrays: #include <iostream> using namespace std; void main() { int m; // int m=10; cin>>m; const int m=10; int arr[m]; for(int i=0; i<m; i++) { arr[i]=i*10; cout << arr[i] << ‘ ‘; } }

  25. Exercises/Tasks • To demonstrate command line arguments in Code::Blocks • Back to Code::Blocks • Write a C++ program: void main(int argc, char *argv[]) { for(int i=0; i<argc; i++) { cout << ‘\n’ << argv[i]; } } • Run the program without command-line arguments • Run the program with command-line arguments. How to specify? • Open cmd line window and run the program

  26. Exercises/Tasks • Write CompactProg project to calculate • Factorilal: facti(7), factr(7) • GCD: gcdi(40,15), gcdr(40,15) • Fibonacci: fibi(5), fibr(5) • All functions and main() in the same file

  27. Exercises/Tasks #include <cstdlib> #include <iostream> using namespace std; int factr(int); int facti(int); int gcdr(int, int); int fibr(int); int main(int argc, char *argv[]) { cout << factr(6) << “ “ << facti(6)<< “ “; cout << ‘\n’ << gcdr(40,15); cout ,, ‘\n’ << fibr(5); system("PAUSE"); return EXIT_SUCCESS; }

  28. Exercises/Tasks int factr(int n) { if (n==0 ) return 1; return n *factr(n-1); } int facti(int n) { if (n==0 ) return 1; int res=1; for (int i=1; i <=n; i++) res *=i; return res; }
