1. Guidelines for working with Microsoft Visual Studio 6

2. Create a new Project

3. Select Project Type

5. Create New File

6. Write the Code

7. Stage 2: Compile

8. Create Executable File

9. Stage 3: Execute

10. Execution Window

11. Inserting a breakpoint Press right mouse button and select “Insert Breakpoint”

12. Start Debugging

13. Stopping at a Breakpoint The “Watch” window will show the values of the variables

14. Stepping Over “Step over” and check the values in the “Watch” window

15. Run to Cursor “Run to cursor” will run till the current cursor position

16. Checking a value of a variable

17. Choose “Add Watch” to a variable to the “Watch” window

18. Factorial #include int main(void) { int i,n, fact=1; printf("Enter a number: "); scanf("%d", &n); for (i =1; i<=n; i++){ fact*=i; } printf ("\nThe functorial is: %d\n", fact); return 0; }

19. Stepping through a Loop

20. Errors Syntax errors – caught by compiler Run-time errors - seen during program execution. Reasons for run-time errors: –Infinite loops –Division by zero –Many more … Important Termination Commands: –Unix: -C –MS-DOS: -C or -break

21. Compilation Errors Example

22. Run Time Error Example Don’t try this at home!!!

23. Infinite Loop Don’t try this at home!!! Use C to terminate the execution

24. Code and Compilation Examples

25. Printing Numbers #include int main(void) { int i; for(i=0; i<100; i++){ printf("%d\n", i); } return 0; }

26. Printing Numbers #include int main(void){ int i,j; for(i=0; i<20; i++){ for(j=0;j<20;j++){ printf("%d ", i); } printf("\n"); } return 0; }
