C++ Programming Basics Quiz

Question 1 (Multiple Choice)

• Question Type: Choose the correct answer from a given set of options.
• Topic Covered in Question 1: C++ programming, output of code snippets, arithmetic and logical operations in C++.
• Key Facts: The questions involve the evaluation of code fragments, including statements involving if statements (if/else structure), for loops, while loops, variable assignment, and output. These code examples address basic C++ syntax, control flow (while/for), output formatting, variable declarations/initializations, and arithmetic calculations (integer and floating-point).

Question 2 (Coding)

• Topic Covered: Creating a program to determine if an integer is prime.
• Key Concept: Prime number definition: A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. Prime numbers are only divisible by 1 and themselves.
• Programming Logic: The program needs to take an integer input, check divisibility from 2 up to the input number itself. If it is divisible by a number other than 1 and itself, it is not prime.

Question 3 (Conversion)

• Topic Covered: Converting a while loop to a do-while loop.
• Key Concepts: Different loop structures in C++ (while, do-while, and for); these loops are structures to repeat code blocks while a condition remains true.
• Logic: The conversion changes the location of the loop condition, allowing the block of code within the loop to execute at least once.

Question 4 (Coding)

• Topic Covered: Drawing a chessboard pattern using C++ output.
• Key Concept: Using nested loops for iteration and conditional statements to structure patterns; Character representation \u2588 represents a chessboard square.
• Pattern: The program creates an 8x8 board using a nested for loop. Alternating squares are filled with either the character string “\u2588\u2588\u2588” (3 \u2588 characters) or 3 spaces depending if the square is black or not.
• Output: The code should create a chessboard pattern on the console.
