Is there a difference between int& a and int &a? - Stack Overflow
Dec 30, 2011 · int& a; // & associated with type int &a; // & associated with variable Associating the & or * with the type name reflects the desire of the programmer to have a separate pointer type. However, the difficulty of associating the & or * with the type name rather than the variable is that, according to the formal C++ syntax, neither the & nor the * is distributive over a list of …

Stackoverflow.comc++ - What does int & mean - Stack Overflow
Sep 14, 2016 · It returns a reference to an int. References are similar to pointers but with some important distinctions. I'd recommend you read up on the differences between pointers, references, objects and primitive data types.
Stackoverflow.comWhat range of values can integer types store in C++?
Nov 30, 2009 · To represent the largest value of an "int 4 bytes" on this architecture, you would need 32 ones, meaning (2 x 2^31) - 1 = 4294967295 for the "unsigned long int" data type. ( You would need to write your own binary to decimal conversion program in any language without using pre-defined library or method to understand this more, trust me.
Stackoverflow.comIs the size of C "int" 2 bytes or 4 bytes? - Stack Overflow
Feb 13, 2014 · The only guarantees are that char must be at least 8 bits wide, short and int must be at least 16 bits wide, and long must be at least 32 bits wide, and that sizeof (char) <= sizeof (short) <= sizeof (int) <= sizeof (long) (same is true for the unsigned versions of those types). int may be anywhere from 16 to 64 bits wide depending on the platform.
Stackoverflow.comc - What does (int*) &var mean? - Stack Overflow
Feb 15, 2015 · First off, the conversion (int *) &var converts char * to int *, which is explicitly allowed by §6.3.2.3p7 if and only if the value of the pointer-to-char is properly aligned for an object of type int. A pointer to an object type may be converted to a pointer to a different object type.
Stackoverflow.comWhat is the difference between int, Int16, Int32 and Int64?
Mar 14, 2012 · int is a primitive type allowed by the C# compiler, whereas int32 is the Framework Class Library type (available across languages that abide by CLS). In fact, int translates to int32 during compilation. Also, In C#, long maps to System.int64, but in a different programming language, long could map to int16 or int32.
Stackoverflow.comJava - Convert integer to string - Stack Overflow
int i = 1234; String str = integer.toString(i); Returns a String object representing the specified integer. The argument is converted to signed decimal representation and returned as a string, exactly as if the argument and radix 10 were given as arguments to the toString(int, int) method.
Stackoverflow.comWhat is the maximum value for an int32? - Stack Overflow
Sep 19, 2008 · To get max value you actually have to calculate the sum of 2^n with n from 0 to 31 or simpler 2^32 - 1 and you'll get '4294967295' as max for unsigned int, one less than anticipated. Now do the same with 2^31 - 1 for signed int and you'll get 2,147,483,647 .
Stackoverflow.comWhat does the C++ standard say about the size of int, long?
Char : 1 byte short : 2 bytes int : 4 bytes long : 4 bytes float : 4 bytes double: 8 bytes I tried to find, without much success, reliable information stating the sizes of char, short, int, long, double, float (and other types I didn't think of) under different architectures and compilers.
