Control structure

It is a fundamental component that determines the flow of execution of instructions in a program. It governs which instructions are executed, when, and under what conditions.

Control structure

It allows programs to make decisions, perform repeated tasks, and respond dynamically to different inputs or conditions—essential for building complex, responsive software.

Sequential Structure

This is the simplest form of control where statements or instructions are executed one after another in the exact order in which they are written.

does not

Sequential structure is used to carry out a linear set of operations where the flow (does / does not) require any decision-making or repetition.

fixed sequence

Sequential structure is commonly applied in tasks that must be performed in a f______ s__________ with no deviation

Sequential Structure

This control structure is common in initialization routines, data input/output operations, and procedural steps.

Selection (Decision-Making) Structure

This executes a block of code only if a condition is true. It allows the program to choose between alternative paths of execution based on whether a condition is true or false. This enables decision-making capabilities in the program.

Selection (Decision-Making) Structure

This is commonly applied in scenarios requiring branching logic, such as validation checks, menu selections, or rule-based execution (e.g., user authentication and eligibility determination).

branching logic

Selection (Decision-Making) Structure is commonly applied in scenarios requiring b____________ l_______

Selection (Decision-Making) Structure

User authentication and eligibility determination is an example of which control structure?

If-else and if-elif-else

Selection (Decision-Making) Structure use the following keyword:

if

This keyword is used to begin a conditional block that runs if the condition is true

else

This keyword is used to execute its block if the condition is false.

elif

This keyword is short of “else if”

elif

This keyword is used to evaluate additional conditions if previous ones are false.

Iteration (Looping) Structure

This repeats a block of code as long as a specified condition is true. It is used to automate repetitive tasks without manual code duplication.

Iteration (Looping) Structure

It promotes efficiency and reduces errors by encapsulating repeat logic.

Iteration (Looping) Structure

This is commonly applied in traversing data structures, generating reports, implementing counters, or processing batches

Iteration (Looping) Structure

Looping through user records and retry mechanisms is an example of which control structure?

for and while

Iteration (Looping) Structure uses the following keyword:

for

This keyword begins the counting loop.

while

This keyword begins a loop that continues as long as the condition is true.

break, continue, return

Jump (Branching) Structure alters the flow explicitly using b____, c_________, r________, etc.

Jump (Branching) Structure

It interrupts or redirects the normal flow of control using statements that cause execution to jump to another part of the code.

loops, iterations, function

Jump (Branching) Structure provides exceptional flow control, particularly in exiting l______ early, skipping i____________, or terminating a f________.

break, continue

These keywords are used in loop control

return

This keyword is used in early function termination

error-handling, system-level

Jump (Branching) Structure is used in specific e_______ h_________ and s________ l_______operations (e.g., skipping invalid entries, exiting on critical errors).

break

This keyword terminates the loop immediately.

continue

This keyword is used to skip the current loop iteration and proceed to the next.
