10. C/C++ Expressions
10.1 Writing C/C++ Expressions
You can use C/C++ expressions consisting of the tokens shown below for registering C watchpoints
and for specifying the values to be assigned to C watchpoints.
Token

10.1.1 Immediate Values
You can use hexadecimals, decimals, octals as immediate values. Values starting with 0x are
processed as hexadecimals, those with 0 as octals, and those without either prefix as decimals.
Floating-point numbers can also be used to assign values to variables.
Notes
• You cannot register only immediate values as C watchpoints.
• The immediate value is effective only when it is used in C/C++ language expressions that specify
C/C++ watchpoints or when it is used to specify the value to be assigned to those expressions.
When using floating-point numbers, operation cannot be performed on an expression like 1.0+2.0.
