4.10.Summary of Control Flow Statements #

The if-then statement is a crucial control flow statement that instructs a program to execute a specific section of code only if a specific test generates a true result. It allows for a secondary execution path when a “if” clause evaluates to false. The switch statement allows for infinite execution paths. While and do-while statements execute a block of statements continuously while a specific condition is true. Do-while evaluates at the bottom of the loop, ensuring that the statements within the do block are executed at least once. The for statement is a concise method for iterating over a set of values.
