Determine if map contains a value for a key?
... the map for a keyvalue that is '2'. IIRC the C++ compiler will implicitly convert '2' to an int, which results in the numeric value for the ASCII code for '2' which is not what you want.
Since your keytype in this example is int you want to search like this: m.find(2);
...
Testing whether a value is odd or even
... numbers are floats in JavaScript and using a bitwise operator means first converting it into an int, then performing the operation, and then converting it back to a floating point number.

What is the difference between char array and char pointer in C?
...s provided where one of type char* is expected, the compiler automatically converts the array into a pointer to its first element.
Your example function printSomething expects a pointer, so if you try to pass an array to it like this:
char s[10] = "hello";
printSomething(s);
The compiler pretend...

Here I have found the solution. It was written in Java, but I have converted it to C#. I hope it will help you.
Here's the code in C#:
static void Main(string[] args)
{
string str = "ABC";
char[] charArry = str.ToCharArray();
Permute(charArry, 0, 2);
Console.ReadKey();
}

dynamic_cast and static_cast in C++
... a class Base of which there is a derived class Derived, dynamic_cast will convert a Base pointer to a Derived pointer if and only if the actual object pointed at is in fact a Derived object.
class Base { virtual ~Base() {} };
class Derived : public Base {};
class Derived2 : public Base {};

Remove underline from links in TextView - Android
...which is the case for a basic http:// link. However, Linkify is smart and converts a phone number like (212) 555-1212 into the URL tel:2125551212. The new URLSpanNoUnderline call should be passed span.getURL() to retain this info, otherwise you generate bad links that cause exceptions when clicked...
java: HashMap not working
...foo", new Integer(3));
Auto-boxing means the first version is implicitly converted to the second. Auto-unboxing means you can write:
int i = myMap.get("foo");
instead of:
int i = myMap.get("foo").intValue();
The implicit call to intValue() means if the key isn't found it will generate a Null...
Add leading zeroes to number in Java? [duplicate]
...s, then applying it directly to the number. The format for this example is converted as follows:
%% --> %
0 --> 0
%d --> <value of digits>
d --> d
So if digits is equal to 5, the format string becomes %05d which specifies an integer with a width of 5 printing leading zeroes. S...
