Expressions and Declarations in C++ Programming
To perform a calculation in the C=++ program you need and expression. An expression is a statement that has both a value and a type. In the C++ program, a declaration is statement that defines a variable or it’s a “holding tank” for some sort of value like a number or character.
Expressions
Expressions take one of the following forms:
objName // for a simple object
operator expression // for unary operators
expr1 operator expr2 // for binary operators
expr1 ? expr2 : expr3 // for the ternary operator
funcName([argument list]); // for function calls
Declarations
Declarations use both intrinsic and user-defined types. The intrinsic types are
[<signed | unsigned >]char
[<signed | unsigned >]wchar_t
[<signed | unsigned>] [<short | long | long long>] int
float
[long] double
bool
