// Convert from degrees to radians via multiplication by PI/180

Can code that is valid in both C and C++ produce different behavior when compiled in each language?
..., is going to (most likely) result in different values in i in C and C++:
int i = sizeof('a');
See Size of character ('a') in C/C++ for an explanation of the difference.
Another one from this article:
#include <stdio.h>
int sz = 80;
int main(void)
{
struct sz { char c; };

Is there a difference between x++ and ++x in java?
...
++x is called preincrement while x++ is called postincrement.
int x = 5, y = 5;
System.out.println(++x); // outputs 6
System.out.println(x); // outputs 6
System.out.println(y++); // outputs 5
System.out.println(y); // outputs 6

Array_merge versus + [duplicate]
..., array_merge() concat index-array values.
If not, the index-array will to convert to values array, and then convert to assoc array.
Now it got two assoc array and merge them together, when key conflict, right(last) value will be kept.
array_merge(null, array()) returns array() and got a warning sai...
