I need to declare two different constants in my app one is a simple string, the other needs to be a uint32. I know of two different ways to declare constants as follows #define VERSION 1; //I am not sure how this works in regards to uint32.. but thats what I need it to be. ...
Constants are fields whose values are set at compile time and can never be changed. Use constants to provide meaningful names instead of numeric literals ("magic numbers") for special values. 備註 In C# the #define preprocessor directive cannot be used to define constants in the way that is ...
Ultimately, you can also cast the const-ness away (but keep in mind that the need to do so is almost always a sign of bad design/need to refactor): class A { public: bool has() const { return const_cast<A*>(this)->get().length(); } string& get() { /* huge code here */...

It uses predefined macro expression from C standard math library. The library defines multiple common mathematical constants, which are listed in the following table. M_PI macro can be assigned to a floating point variable or used as a literal value in calculations. Notice that we are using the...
>>>It means, that a set of values 1.0,1.0,1.0,1.0 is moved from a memory (!) to xmm0 register. Once again, both instructions, that is movdqa and movups, can not work with constants by design>>> I misunderstood the problem.In my code the load is coming from the memory and this ...
These descriptors are predefined constants in Unix-based systems. The dprintf function, accessible through the <stdio.h> and <unistd.h> headers, streamlines the process of printing to stderr. The main distinction between fprintf and dprintf lies in the first argument. The dprintf takes a file ...
After that, I can used the #define as if they would have been set in the source code. For example I can store them in constants for later use, similar to the __FILE__ macro: 1 2 3 4 staticconstcharfileName[] = __FILE__; ...
