Section IV—Expressions, Statements, and Program Flow
Summary: Expressions and Statements
In C, expressions represent values, and statements represent instructions to the computer.
An expression is a combination of operators and operands. The simplest expression is just a constant or a variable with no operator, such as 22 or beebop. More complex examples are 55 + 22 and vap = 2 * (vip + (vup = 4)).
A statement is a command to the computer. Any expression followed by a semicolon forms a statement, although not necessarily a meaningful one. Statements can be simple or compound. Simple statements terminate in a semicolon, as shown in these examples:
|Declaration statement||int toes;|
|Assignment statement||toes = 12;|
|Function call ...|
