A flag is a boolean variable that signals the existence of a certain condition in a program. It is usually used in conditional statements to determine whether or not a certain block of code should be executed. Sentinel typically refers to a special value used to indicate the end of a sequence or provide certain input to the program. Block refers to a group of statements that belong together and are often enclosed in curly braces. Case is used in switch statements to specify different actions to take depending on the value of a certain expression.
