on the status pane. The gcd function and its test program have no errors, and the build message
is shown in Figure 5.32.
Unlike CodeWarrior, ICC12 does not have source-level debugging capability. The user
will need to use the D-Bug12 monitor commands to find out whether the program executes
correctly. Since variables declared within a function (including the main function) are local
variables, they are allocated in the stack and hence become invisible when the function is ex-
ited. In order to view the program execution result, the variables of interest must be declared
as global variables (i.e., outside all functions). In this example, the declaration of the variable
result
should be moved out of the main function.
