  • c++ - What does int mean - Stack Overflow
    A C++ question, I know int* foo (void) foo will return a pointer to int type how about int foo (void) what does it return? Thank a lot!
  • What does int() do in C++? - Stack Overflow
    -2 int() is the constructor of class int It will initialise your variable a to the default value of an integer, i e 0 Even if you don't call the constructor explicitly, the default constructor, i e int() , is implicitly called to initialise the variable Otherwise there will be a garbage value in the variable
  • Is there a difference between int a and int a? - Stack Overflow
    int a = 5; int b = a; b = 7; cout << a; prints out 7, and replacing int b with int b also prints out 7 In fact so does int b and int b I tested this kind of behavior with a simple class as well In general, does it ever matter whether the ampersand is placed relative to the type and identifier? Thanks
  • The real difference between int and unsigned int
    The real reason that this can happen is that C is a weakly typed language But unsigned int and int are really different
  • What is the difference between signed and unsigned int
    29 int and unsigned int are two distinct integer types (int can also be referred to as signed int, or just signed; unsigned int can also be referred to as unsigned ) As the names imply, int is a signed integer type, and unsigned int is an unsigned integer type
  • C C++ int [] vs int* (pointers vs. array notation). What is the . . .
    I know that arrays in C are just pointers to sequentially stored data But what differences imply the difference in notation [] and * I mean in ALL possible usage context For example: char c[] =
  • What is the difference between short int and int in C?
    How is short int (or short) and int different in C? They have the same size and range If they are essentially the same, what is the use of having two data types?
  • Why does dividing two int not yield the right value when assigned to . . .
    7 c is a double variable, but the value being assigned to it is an int value because it results from the division of two int s, which gives you "integer division" (dropping the remainder) So what happens in the line c=a b is a b is evaluated, creating a temporary of type int the value of the temporary is assigned to c after conversion to type
  • Whats the difference between int and int_fast16_t?
    On the other hand, int_fast16_t is like providing a hint to the compiler that it should use a type that is optimum for performance, possibly at the expense of any other tradeoff Likewise, int_least16_t would tell the compiler to use the smallest type that's >= 16-bits, even if it would be slower Good for preserving space in large arrays and
