  • 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
  • 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
  • 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
  • int* i; or int *i; or int * i; - i; - Software Engineering Stack Exchange
    64 I prefer int* i because i has the type "pointer to an int", and I feel this makes it uniform with the type system Of course, the well-known behavior comes in, when trying to define multiple pointers on one line (namely, the asterisk need to be put before each variable name to declare a pointer), but I simply don't declare pointers this way
  • 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
  • Can an int be null in Java? - Stack Overflow
    In Java, int is a primitive type and it is not considered an object Only objects can have a null value So the answer to your question is no, it can't be null But it's not that simple, because there are objects that represent most primitive types The class Integer represents an int value, but it can hold a null value Depending on your check method, you could be returning an int or an
  • 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 Integer and int in Java?
    An int variable holds a 32 bit signed integer value An Integer (with capital I) holds a reference to an object of (class) type Integer, or to null Java automatically casts between the two; from Integer to int whenever the Integer object occurs as an argument to an int operator or is assigned to an int variable, or an int value is assigned to an Integer variable This casting is called boxing
