Question

Difference bw implicit explicit sequence control

Answer 1

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.

Answer 2

Answer: Implicit sequence control structures are those described by the language. Explicit sequence control structures are those described by the programmer to change the implicit sequence control defined by the language.

Explanation:

Given : Difference between implicit and explicit sequence control

To Find : Difference between implicit explicit sequence control ?

Concept :

Sequence control describes the line-by-line working by which instructions are implemented sequentially, in the same order in which they occur in the program. A sequence control structure is of two types : implicit or explicit sequence control.

• Implicit Sequence Control − Implicit sequence control structures are those described by the language. Implicit sequence control is decided by the sequence of the statements or instructions in the source code or by the pre-defined implementation model. The implicit sequence control structure tends to be in outcome except that transformed by the programmer explicitly in the code.

• Explicit Sequence Control − Explicit sequence control structures are those described by the programmer to change the implicit sequence control defined by the language.
