Why do we need extern “C”{ #include } in C++?
...the prototype as a C function, the C++ will actually generate code calling _Zprintf, plus extra crap at the end.)
So: use extern "C" {...} when including a c header—it's that simple. Otherwise, you'll have a mismatch in compiled code, and the linker will choke. For most headers, however, you won'...

Is there a math nCr function in python? [duplicate]
...
def nCr(n,r):
f = math.factorial
return f(n) / f(r) / f(n-r)
if __name__ == '__main__':
print nCr(4,2)
In Python 3, use the integer division // instead of / to avoid overflows:
return f(n) // f(r) // f(n-r)

Why are preprocessor macros evil and what are the alternatives?
....
Another example is "if else" in macros, say we have this:
#define safe_divide(res, x, y) if (y != 0) res = x/y;
and then
if (something) safe_divide(b, a, x);
else printf("Something is not set...");
It actually becomes completely the wrong thing....
Replacement: real functions.

The macro is somewhat misnamed; it should be something more like BUILD_BUG_OR_ZERO, rather than ...ON_ZERO. (There have been occasional discussions about whether this is a confusing name.)
You should read the expression like this:
sizeof(struct { int: -!!(e); }))
(e): Compute expression e....
