Understanding the use of the three basic programming constructs

• What is the most basic programming construct in which instructions are executed one after the other in a specific order?

  Sequential structures
• Match the programming construct with its definition:

  Sequential ↔️ Instructions executed in order

  Conditional ↔️ Instructions executed based on a condition

  Iterative ↔️ Instructions repeated until a condition is met
• Sequential structures allow programs to make decisions based on conditions.

  False
• The if-else statement is a common example of a selection structure.


  True
• Arrange the following steps in the correct order to determine if a number is positive or negative using a selection structure:

  1️⃣ Set the number

  2️⃣ Check if the number is greater than or equal to 0

  3️⃣ Print "The number is positive" if true

  4️⃣ Print "The number is negative" if false
• A for loop allows a block of code to be executed a specific number of times
• What is the defining characteristic of sequential structures?

  Executed in order
• In a program to calculate the area of a rectangle, the area is computed using the formula: length * width
• Comparison operators are used in selection structures to evaluate conditions.


  True
• What is the primary purpose of iteration structures in programming?

  Repetition
• What is the output of the given for loop?

  0, 1, 2, 3, 4
• Iteration structures enable repetition of instructions until a condition is met.


  True
• Sequential structures execute instructions based on a condition being true or false.

  False
• Arrange the following steps in the correct order to calculate the area of a rectangle using a sequential structure:

  1️⃣ Set the length

  2️⃣ Set the width

  3️⃣ Multiply length by width

  4️⃣ Print the result
• Selection structures use comparison operators such as less than (<), greater than (>), equal to (==), and not equal to (!=)
• In a selection structure, the condition determines which instructions are executed.
• What is a common example of an iteration structure that executes a block of code a specific number of times?

  For loop
• Sequential structures are fundamental to programming because they allow tasks to be performed in a controlled and predictable manner
• How do sequential structures compare to conditional structures?

  Executed in order
• What are selection structures used for in programming?

  Decision-making
• How do selection structures compare to sequential structures?

  Based on conditions
• How many times does the 'print(i)' statement execute in the example for loop?

  5
• Match the programming construct with its definition:

  Sequential ↔️ Instructions executed in order

  Selection ↔️ Instructions executed based on conditions

  Iteration ↔️ Instructions repeated until a condition is met
• Sequential structures form the backbone of most algorithms and programs
• What type of programming structure is used to calculate the area of a rectangle in a simple program?

  Sequential structure
• What are programming constructs called where the execution of instructions depends on a condition being true or false?

  Selection structures
• What type of programming structure is used to determine if a number is positive or negative?

  Selection structure
• Iteration structures repeat instructions until a specific condition is met or a certain number of times.


  True
• In a for loop, the loop variable 'i' increases by 1 in each iteration.


  True
• Sequential structures execute instructions from top to bottom.


  True
• What are the values of length and width in the example program to calculate the area of a rectangle?

  5 and 3
• A common example of a selection structure is the if-else
• A common example of an iteration structure is the for loop
• What are the three basic programming constructs mentioned in the study material?

  Sequential, selection, iteration
