Sequence refers to the straightforward execution of statements in a program from top to bottom, in the order they are written. Selection, also known as decision-making, allows the program to make choices based on conditions (e.g., “if-else” statements) and execute different code blocks based on the condition being true or false. Iteration involves repeating a … Read more
Loops are essential control structures in programming that allow a set of instructions to be executed repeatedly based on a condition. They help avoid redundant code, enhance program efficiency, and make the code more readable and maintainable. There are various types of loops such as “for”, “while”, and “do-while,” each serving different purposes. For example, … Read more

Print the multiplication table of a number in reverse order Problem Statement: Given a number, print its multiplication table in reverse order. Algorithm: Start Input the number (N). For each multiple from 10 to 1 (i.e., 10, 9, 8, …, 1), do the following: Multiply N by the current multiple. Print the result of the … Read more
The product of a given sequence of numbers Problem Statement: Given a sequence of numbers: 1, 3, 5, 7, 9, 11, 13, 15, find their product. Algorithm: Start Initialize a variable product to 1. Multiply each number in the sequence with product: Multiply product by 1. Multiply product by 3. Multiply product by 5. Multiply … Read more
The sum of a given sequence Problem Statement: Given a sequence: 20, 25, 30, 35, 40, 45, 50, 55, 60, calculate the sum. Algorithm: Start Initialize a variable sum to 0. Add each number in the sequence to sum: Add 20 to sum. Add 25 to sum. Add 30 to sum. Add 35 to sum. … Read more
Convert inches to centimeters Problem Statement: Input a length in inches and convert it into centimeters (1 inch = 2.54 cm). Algorithm: Start Input the length in inches (inches). Convert the length to centimeters using the formula: centimeters=inches×2.54\text{centimeters} = \text{inches} \times 2.54centimeters=inches×2.54 Display the length in centimeters. End Explanation: To convert inches to centimeters, we … Read more
Problem Statement: Given the length and breadth of a rectangle, calculate the area. Algorithm: Start Input the length (L) of the rectangle. Input the breadth (B) of the rectangle. Calculate the area using the formula: Area=L×B\text{Area} = L \times BArea=L×B Display the calculated area. End Explanation: The area of a rectangle is simply the product … Read more
Problem-solving typically involves the following steps: Understanding the problem: Clearly define the problem, its constraints, and requirements. Analyzing the problem: Break the problem into smaller, manageable parts and identify relevant information. Designing a solution: Develop possible solutions or approaches, considering resources, time, and feasibility. Implementing the solution: Put the chosen solution into action, ensuring to … Read more
