Examining Data

DDD provides several means to examine data.

• The quickest way to examine variables is to move the pointer on an occurrence in the source text. The value is displayed in the source line; after a second, a popup window (called

  ) shows the variable value. This is useful for quick examination of several simple values.

• If you want to refer to variable values at a later time, you can

  the value in the debugger console. This allows for displaying and examining larger data structures.

• If you want to examine complex data structures, you can

  them graphically in the data window. Displays remain effective until you delete them; they are updated each time the program stops. This is useful for large dynamic structures.

• If you want to examine arrays of numeric values, you can

  them graphically in a separate plot window. The plot is updated each time the program stops. This is useful for large numeric arrays.

• Using GDB or DBX, you can also

• Value Tips: Just move the pointer on a variable.

• Printing Values: Printing a value in the debugger console.
• Displaying Values: Displaying structures as graphs.
• Plotting Values: Displaying values as plots.
• Examining Memory: Low-level memory examination.
