Introduction to C++

The compound statement or block is a treated as a single unit and may appear anywhere in the program. . Control Statements Control statements are statements that alter the sequence of flow of instructions. In a program, statements may be executed sequentially, selectively or iteratively.

Every programming languages provide statements to support sequence, selection (branching) and iteration. If the statements are executed sequentially, the flow is called as sequential flow. In some situations, if the statements alter the flow of execution like branching, iteration, jumping and function calls, this flow is called as control flow. Sequence statement The sequential statement are the statements, that are executed one after another only once from top to bottom.

These statements do not alter the flow of execution. These statements are called as sequential flow statements. They always end with a semicolon (;). Selection statemen t
