Expressions in C++
An expression in C++ is any valid combinations of operators, constants and variables .
Types of Expressions :
The expressions in C++ can be of any type :
- Arithmetic Expression
- Relational Expression (or Logical Expression)
- Compound Expressions etc.
Arithmetic Expressions can be either Integer Arithmetic Expression or Real Expressions or mixture of both.
- Integer Constants are made up of integer constants and/or integer variable
- Real Expressions are made up of real constants and/or real variables
Examples of integer Expressions and Real Expressions :
Logical Expressions are the expressions that results o(false) or 1(True). These expressions are combination of constants, variables and logical and relational operators.
Examples of some valid Logical Expressions are –
Assignment Statements –
These statements assigns a value to a variable. The value assined may be a constant variable or an expression. These can be chained together also.
Example of Assignment Statements :
In the above chained assignment statement, value 13 is assigned to all the variables x,y,z. Firstly, 13 is assigned to z, then the new value of z is assigned to y, and finally the new value of y is assigned to x.
