(2.2) Saving/Running Your Project or Your Source Codes

a.1. Saving Your Program:

DO NOT save your program codes on the computer in the software lab (N327

or N329). All files on those computers will be regularly deleted.

a. Open Project using Step (2.1) on page 16.

b. Build and Run Program using Step (1.6) on page 14.

3. Useful Tips

(3.1) Using Help

a.1. Click Help Index

Figure 3.1 Starting Help

a.2. Type in commands you want to get help and Enter. E.g., type printf

a.3. Close the Help Window

by Clicking X in the top right (where red circle mark is) in Figure 3.5.

(Note: You can leave this window open, while working on the program.)

4. Debugging Programs using Breakpoints

- Breakpoints can be very useful when you want to debug your program.

Using break points, you can examine how your program is working.

For example, you can watch how variables are changing.

The following examples illustrate how to run programs in debugging mode.

Example 1) This program adds integer numbers from 1 to 10 and prints the sum using

a for loop.

Using a break point, we see how the variable i, sum are changed.

a.1. Create a Project (i.e., Test2) and Write the Following Program (test2.cpp) in

Figure 1.1 using Steps (1.2) ~ (1.6) on pages 3~8.

15


16/25

Figure 1.1 Example Program: test2.c

a.2. Move the cursor to the line where you want to insert a breakpoint.

Figure 1.2 Moving Your Cursor

a.3. Right Mouse Click and select Breakpoint Insert Breakpoint (or F9).

16


17/25

Figure 1.3 Inserting a Breakpoint

a.4. A breakpoint (i.e., red dot) is inserted.

Figure 1.4 A Breakpoint

(a.5. Right Mouse Click and Breakpoint) Delete Breakpoint)

Figure 1.5 Deleting a Breakpoint

a.6. Running your program in debugging mode: Debug Start (or F5).

Figure 1.6 Debugging Mode

Note: If the error message in Figure 1.61 occurs, follow the Steps a.6. (1)~(5).

Figure 1.61 Debugging Error Message

a.6. (1) Select Project test2 Properties (Figure 1.62)

Figure 1.62 Changing Project Property

a.6. (2) Expand C/C++ and Linker by clicking +

18

a.6. (3) Select General Menu under C/C++ and change Disabled to C7

Compatible (/Z7) under Debug Information Format (Figure 1.63)


a.6. (4) Select Debugging Menu under Linker

a.6. (5) Change No to Yes (/DEBUG) under Generate Debug Info and click

OK (Figure 1.64)

19

a.7. Program stops at the breakpoint andvariables in the function are shown at the bottom (e.g., i and sum).

Figure 1.7 Variable Watch 1 (i = 1, sum= 0)

a.8. Continue your program: Debug Continue (or F5).

Program stops at the breakpoint again and values of variables are changed.

20


21/25

Figure 1.8 Continuing Debugging


a.9. Repeat Continue (or F5), then you see how the variables are changed.

21


22/25


a.10. Exit debugging: Debug Stop Debugging (or Shift+F5)

Figure 1.11 Exiting Debugging Mode

Example 2) This program adds even integer numbers and multiplies odd integer

numbers from 0 to 10 and prints the result using a for loop.

Using a break point, we see how the variable i, num are changed.

a.1. Create a Project (i.e., Test6) and Write the Following Program (i.e., test6.c) in

Figure 2.1. (See Steps (1.2) and (1.3) on pages 4~8 of Manual I.)

22


23/25

Figure 2.1 Example Program: test6.c

a.2. Move the cursor to the line where you want to insert a breakpoint and insert a

break point using Step a.2 ~ a.4 in Example 1.

Figure 2.2 A Breakpoint Inserted

a.3. Run your program in debugging mode: Debug Start (or F5)

Figure 2.3 Program Stopped at the Breakpoint

Note: If the program is in debugging mode, but you dont see your program

variables as in Figure 2.3 (a), follow the Steps a.3. (1)~(4).

Figure 2.3 (a) Debugging Mode Error

a.3. (1) Exit Debugging Mode: Debug Stop Debugging (see Figure 1.11)

a.3. (2) Project Test6 Properties

a.3. (3) Expand Configuration Properties C/C++ and Click Optimization

a.3. (4) Change the Any Optimization Option to Disabled(/Od)

Figure 2.3 (b) Changing Project Properties 4

a.4. Continue Debugging using Debug Step Over (or F10)

If you continue debugging using Debug Continue (or F5), the debugging will

be ended since there is only one breakpoint in the program and it is not within the for

loop. Using Step Over, you can debug in line-by-line fashion. (Yellow arrow

indicates the current line.)

Figure 2.4 Debugging: Yellow Arrow at for loop

a.5. Keep Continue Debugging using Debug Step Over (or F10) (2 times)

Figure 2.5 Debugging: Yellow Arrow at num += i;

a.6. Keep Continue Debugging using Debug Step Over (or F10)

Figure 2.6 Debugging: Yellow Arrow at num *= i;

a.7. Exit debugging: Debug Stop Debugging (see Figure 1.11)
