Term sequence structure

The control structure that directs the computer to repeat one or more instructions until some condition is met, at which time the computer should stop repeating the instructions; also called a loop or iteration.

In this manner, what programming concept allows a computer to repeat a set of instructions over and over again? Iteration A loop will repeat a certain segment of code until a condition is met and it can proceed further. Each time the computer runs a loop, it is known as an iteration.

The CPU is the heart of the computer. A program is a sequence of instructions stored in main memory. When a program is run, the CPU fetches the instructions and executes or follows the instructions.

Explain that, when used in a program, the repetition structure directs the computer to repeat one or more instructions until some condition is met, at which time the computer should stop repeating the instructions. Note that the repetition structure is also referred to as a loop or iteration.

“Sequence control structure” refers to the line-by-line execution by which statements are executed sequentially, in the same order in which they appear in the program. They might, for example, carry out a series of read or write operations, arithmetic operations, or assignments to variables.

The three basic types of control structures are sequential, selection and iteration. They can be combined in any way to solve a specified problem. Sequential is the default control structure, statements are executed line by line in the order in which they appear.

Sequence is the default control structure; instructions are executed one after another. They might, for example, carry out a series of arithmetic operations, assigning results to variables, to find the roots of a quadratic equation ax2 + bx + c = 0.

Surprisingly, it can often be broken down into three simple programming structures called sequences, selections, and loops. These come together to form the most basic instructions and algorithms for all types of software.

4 Basic Flowchart Symbols for Creating a Flowchart

• The Oval. An End or Beginning While Creating a Flowchart. The oval, or terminator, is used to represent the start and end of a process.
• The Rectangle. A Step in the Flowcharting Process.
• The Arrow. Indicate Directional Flow.
• The Diamond. Indicate a Decision.

Three Fundamental Control Structures

Types of control structures

• Sequence.
• Selection.
• Repetition.
• Function call.

There are three basic types of logic, or flow of control, known as: Sequence logic, or sequential flow. Selection logic, or conditional flow. Iteration logic, or repetitive flow.

There are three kinds of control structures: Conditional Branches, which we use for choosing between two or more paths. There are three types in Java: if/else/else if, ternary operator and switch. Loops that are used to iterate through multiple values/objects and repeatedly run specific code blocks.

Flow of control through any given function is implemented with three basic types of control structures:

• Sequential: default mode.
• Selection: used for decisions, branching — choosing between 2 or more alternative paths.
• Repetition: used for looping, i.e. repeating a piece of code multiple times in a row.

A control statement is a statement that determines whether other statements will be executed. An if statement decides whether to execute another statement, or decides which of two statements to execute. for loops are (typically) used to execute the controlled statement a given number of times.

What are the unique features of for loop?

• The initialization expression initializes the loop control variable and is executed only once when the loop starts.
• The conditional expression is tested at the start of each iteration of the loop.
• The increment/decrement expression updates the loop control variable after each iteration.

while loop: A while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. The while loop can be thought of as a repeating if statement. Once the condition is evaluated to true, the statements in the loop body are executed.

A control structure is like a block of programming that analyses variables and chooses a direction in which to go based on given parameters. The term flow control details the direction the program takes (which way program control “flows”). Hence it is the basic decision-making process in computing; It is a prediction.

In most computer programming languages, a while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. The while loop can be thought of as a repeating if statement.

Control statements enable us to specify the flow of program control; ie, the order in which the instructions in a program must be executed. They make it possible to make decisions, to perform tasks repeatedly or to jump from one section of code to another.

2 Conditional Statement Another name for an IF-THEN statement is a CONDITIONAL STATEMENT. Every conditional has 2 parts. The part following the “IF” is called the HYPOTHESIS, and the part following the “then” is called the CONCLUSION.

Conditional Statements : if, else, switch.

There are 4 basic types of conditionals: zero, first, second, and third. It’s also possible to mix them up and use the first part of a sentence as one type of conditional and the second part as another. These sentences would be called “mixed conditionals.”

A conditional statement (also called an If-Then Statement) is a statement with a hypothesis followed by a conclusion. The hypothesis is the first, or “if,” part of a conditional statement. The conclusion is the second, or “then,” part of a conditional statement. The conclusion is the result of a hypothesis.

Python supports the following control statements.

• Continue Statement. It returns the control to the beginning of the loop.
• Break Statement. It brings control out of the loop.
• Pass Statement. We use pass statement to write empty loops.
• Exercise:

The decision control statements are the decision making statements that decides the order of execution of statements based on the conditions. In the decision making statements the programmer specify which conditions are to be executed or tested with the statements to be executed if the condition is true or false.

GoTo (goto, GOTO, GO TO or other case combinations, depending on the programming language) is a statement found in many computer programming languages. It performs a one-way transfer of control to another line of code; in contrast a function call normally returns control.
