Implicit and Explicit sequence Control

     A sequence control can be either implicit or explicit.

     Implicit means default i.e the logic or control defined exclusively by the language unless modified by some programmer through explicit or external sequence control.  Example GOTO statements in C or break continue.

     Sequence control is nothing but the flow of a program.

     Suppose we write a small program using if-else ladder.  So, the flow is basically if statements (i.e the condition true) or else statements (i.e the condition is false).  Thus there may be two flow of controls depends upon the condition provided by the user and in any program flow control is started from the keyword main.

    Sequence control is primarily categorized in four groups :-

-> Expression ( Precedence rule and parenthesis ).

-> Statements ( Conditional and iterations statements).

-> Declarative Programming ( declaration of function ).

-> Subprogram ( Subprogram Calls ).

# Expression determines how data are manipulated and changed by a program.

# Statements they are nothing but group of expressions.

# Declarative Programming :-> is an execution model that does not depend on statements and causes execution.

# Subprograms they are call to any procedure or co-routine i.e a way of transfer execution. from one statement to other.

1. Sequence Control :->  It control the order of execution of operations.

2. Data Controls :->  It control the transmission of data among subprogram of a program.

• Structures used in expressions - Precedence rules and parenthesis.
• Structures used between group of statements - Conditional and iterative statements.
• Structures used between subprograms - Subprogram calls.
