Implicit type conversion rules in C++ operators
... 200 + 200 + 200 to 144 + 200, which is 344, which reduces to 88. In other words, the program does not know the difference, so the compiler is free to ignore the mandate to perform intermediate operations in int if the operands have a lower ranking than int.
This is true in general of addition, sub...
Sorting an IList in C#
...
Wonderful answer! However, a word of caution: this approach assumes that the IList<T> list can be cast to the non-generic IList interface. If you code your own class implementing the IList<T> interface, make sure you also implement the non-g...
What is the difference between the $parse, $interpolate and $compile services?
...ded interpolation expressions, ex.: /path/{{name}}.{{extension}}. In other words it can take a string with interpolation expressions, a scope and turn it into the resulting text. One can think of the $interpolation service as a very simple, string-based template language. Given the above example one...
GOTO still considered harmful? [closed]
...ammed yourself so far into a corner that it is the only way out. In other words, proper design ahead of time and you won't need to use a GOTO later.
I thought this comic illustrates that beautifully "I could restructure the program's flow, or use one little 'GOTO' instead." A GOTO is a weak way...

I get it now. The wording of the answer was slightly confusing. The Task itself doesn't have a built in "caching" mechanism. But if you wrote a caching mechanism for ... say .... downloading files, Task<File> GetFileAync( ), you could ...

PHP foreach change original array values
...people on the internet, which is why I decided to add more information and words of caution.
While pass by reference in foreach (or functions) is a clean and short solution, for many beginners this might be a dangerous pitfall.
Loops in PHP don't have their own scope. - @Mark Amery

You can consider the word frame as regular photo frame. What you do with that frame? you can place photos in that frame by one top to another. Same as in FrameLayout we can place views ( Any layout, or widget like button, text, image so on) top o...
Need for predictable random generator
...rs. Let's say that a player has 20% chance to get a critical hit with his sword. That means, 1 out of 5 hits should be critical. The problem is I got very bad real life results — sometimes players get 3 crits in 5 hits, sometimes none in 15 hits. Battles are rather short (3-10 hits) so it's import...
__FILE__, __LINE__, and __FUNCTION__ usage in C++
...
__func__ is kind of a problem in C++. C99 doesn't say a word about default arguments and so forth, cases where it's not so obvious how __func__ should behave in C++.
