Which are the control structures in programming?

Answer 1

control structures are which is used to do some operations with conditions some of them are if,if else,switch,goto,continue..........and loops like for ,while,do while and even break used to break the process on some conditions

Answer 2

SEQUENCE STRUCTURE: an action, or event, leads to the next ordered action in a predetermined order. The sequence can contain any number of actions, but no actions can be skipped in the sequence. The program, when run, must perform each action in order with no possibility of skipping an action or branching off to another action.

The Decision / Selection Structure: In a selection structure, a question is asked, and depending on the answer, the program takes one of two courses of action, after which the program moves on to the next event.

The Loop: While a condition is true. The Loop has two parts: (1) a condition that is tested for true or false value, and (2) a statement or set of statements that is repeated as long as the condition is true.

Answer 3

Depends on the definition of "Control Structures" and the computer language, there may be additional statements available.

NOTE: the terms used below are NOT standard in any way. But I will explain a little to allow you to absorb in your own terms.

The main statements for control the program flow:

Logical branching

If- and if-else , switch or case, catching/handling exceptions

Jump

GO TO, return, yield, break, exit, continue, throwing exceptions

some would consider calling functions or subroutines is a form of jump, I would not.

Iteration

repeat, while, do-while, for, iterate, loop, recursive calls, forever,

There are more control structures, not just 3 kinds,varied from language to language. But I'll throw in another one that may be "hidden" or over-look, and should be available to most of the computer languages:

Evaluation order

left to right or right to left, (), {}, begin-end, operator precedence, short-circuit logical evaluation or not

Answer 4

All programming languages support some form of a conditional control structure, an "if-then" and "if-else-then" style of construct.

All programming languages require a construct to select a code path based on a logic expression, such as a test for equality of two items.

All programming languages also support at least one conditional loop construct for repeated execution of a set of instructions subject to a loop-terminating condition. Common loop control structures are loops which test the condition prior to execution (e.g. "while" and "repeat" loops), and those which test the condition after having executed the loop's instructions at least once (e.g. "do-while" and "repeat-until" loops).

Strictly speaking, only one of these loop forms is required, but different forms loops allow expressing a given solution more elegantly.

Most programming languages also support enumerative constructs or loop forms typically used with enumerations (the "for" or "for-next" loop construct, and the "foreach" construct often supported by modern languages).

"for" and "foreach" loops are convenient short forms of the general loop controls discussed above. While the more modern "foreach" loops often allow for efficient code generation (through use of iterator or enumerator design patterns), these loop forms are strictly speaking unnecessary.

Constructs to express multiple-choice decisions are also often supported, but offer no semantic improvement over nested or repeated "if-else" clauses. The popular "switch-case" control is an example for a multiple-choice control.

Other control structures include methods to terminate a loop, restart a loop, divide code flow unconditionally or terminate a program, e.g. "break", "continue", "goto" and "exit".

The specifics of all these constructs vary and are subject to the chosen language, and not all will support all the above, and some will support even more.

Answer 5

there are 3 types....

they are -

1) sequential

2) conditional

3) unconditional
