Pseudocode serves as a structured form of English used to describe algorithms, enabling designers to concentrate on algorithmic logic without the distraction of language syntax details. In this post, however, we will shift our focus to employing a C-style syntax.
Let’s delve into a practical example to illustrate the application of pseudocode with a C-style syntax in calculating the area and perimeter of a rectangle.

// Define variables for length and width float length, width; // Prompt user for input Print("Enter the length of the rectangle: "); Input(length); Print("Enter the width of the rectangle: "); Input(width); // Calculate area and perimeter float area, perimeter; area = length * width; perimeter = 2 * (length + width); // Display the results Print("Area of the rectangle: ", area); Print("Perimeter of the rectangle: ", perimeter); |
