How to implement static class member functions in *.cpp file?
...
It is.
test.hpp:
class A {
public:
static int a(int i);
};
test.cpp:
#include <iostream>
#include "test.hpp"
int A::a(int i) {
return i + 2;
}
using namespace std;
int main() {
cout << A::a(4) << endl;

Why use apparently meaningless do-while and if-else statements in macros?
...e.
if (corge)
BAR(corge);
else
gralt();
The above code would expand into
if (corge)
f(corge); g(corge);

which is syntactically incorrect, as the else is no longer associated with the if. It doesn't help to wrap things in curly braces within the macro, because a semicolon...
What's the syntax for mod in java
... modulo operator, which has slightly different semantics, for non-negative integers, you can use the remainder operator %. For your exact example:
if ((a % 2) == 0)
{
isEven = true;
}
else
{
isEven = false;
}
This can be simplified to a one-liner:
isEven = (a % 2) == 0;

... to work with such property/value pairs, parse_pv_pairs.m. It helps you to convert property/value pairs into a matlab structure. It also enables you to supply default values for each parameter. Converting an unwieldy list of parameters into a structure is a VERY nice way to pass them around in MATLA...
