Statements (C++)

C++ statements are the program elements that control how and in what order objects are manipulated. This section includes:

  • Overview

  • Labeled Statements

  • Categories of Statements

    • Expression statements. These statements evaluate an expression for its side effects or for its return value.

    • Null statements. These statements can be provided where a statement is required by the C++ syntax but where no action is to be taken.

    • Compound statements. These statements are groups of statements enclosed in curly braces ({ }). They can be used wherever a single statement may be used.

    • Selection statements. These statements perform a test; they then execute one section of code if the test evaluates to true (nonzero). They may execute another section of code if the test evaluates to false.

    • Iteration statements. These statements provide for repeated execution of a block of code until a specified termination criterion is met.

    • Jump statements. These statements either transfer control immediately to another location in the function or return control from the function.

    • Declaration statements. Declarations introduce a name into a program. (Declarations provides more detailed information about declarations.)

For information on exception handling statements see Exception Handling.
