When do we use int in c plus plus programming?

'int' is one of the built-in data-types, it is meant to hold integer values.

Int x2 - 3 dx?

30 examples of variables?

int n1; int n2; int n3; int n4; int n5; int n6; int n7; int n8; int n9; int n10; int n11; int n12; int n13; int n14; int n15; int n16; int n17; int n18; int n19; int n20; int n21; int n22; int n23; int n24; int n25; int n26; int n27; int n28; int n29; int n30;

Why is union used in C?

Union is used in case of libraries which return assorted data's. for example, say a stack library is present which can return an int or double depending on what is on top of stack. in such a case, the application layer should be able to receive from library either int or double. so in application layer we use union.

What is meant by void in c plus plus?

void is used by functions that do not return a value. For example: // This function returns an integer, which you can use in other functions int addTwoNumbers(int a, int b) { return(a + b); } // This function does not return a value, so we declare it as a void void printSum(int a, int b) { cout << a << " + " << b << " = " << addTwoNumbers(a, b) << endl; // Note that attempting to return a value here will cause an error. }

What is meant by named types in Swift programming?

In Swift there are two kinds of type: named and compound. A named type is simply a type that is given a name when it is defined. All the built-in (primitive) data types are named types but you can define your own. A compound type is simply a type without a name and can either be a function or a tuple. Compound types may include both named types and other compound types: (Int (Int, Int)) defines a tuple containing a named type, Int, and another compound type (Int, Int) containing two named types, Int and Int.

How do declare function pointer having two integer parameters and returning integer pointers?

// declare a function int* function(int, int); or int* (function)(int, int); // declare a pointer to a function int* (*pointer_to_function)(int, int);

Why does the temperature go up when you go up int earths atmosphere?

Short answer: Absorption / emission of light. The atmosphere gets thick enough that the oxygen and nitrogen there absorb UV-C and more energetic light, ozone absorbs UV-B (from above) and some infrared (both from above and below, ozone is a greenhouse gas). Where there is little ozone, there is little indication of temperature.

Get size of int using sizeoff?

printf ("sizeof (int) = %d\n", (int)sizeof (int));
