Sure! I can explain how modular programming works and provide you with an example using a do-while loop.
Modular programming is a software design technique that divides a program into smaller and independent modules. Each module performs a specific task and can be reused in different parts of the program. This approach promotes code reusability, readability, and maintainability.
To illustrate this, let's consider a simple example of a program that prints numbers from 1 to 10 using a do-while loop:
1. First, we can define a modular structure by creating a function (module) that performs the printing task:
```pseudo
function printNumbers() {
// Initialize a counter
let counter = 1;
do {
// Print the current number
print(counter);
// Increment the counter
counter += 1;
} while (counter <= 10);
}
```
In this example, the function `printNumbers()` is responsible for printing the numbers using a do-while loop. It initializes a counter variable `counter` with an initial value of 1. Then, it enters a do-while loop that executes the following steps:
1. Prints the value of the `counter`.
2. Increments the `counter` by 1.
3. Checks the condition `counter <= 10`.
If the condition is true, the loop continues, and the next number is printed. If the condition is false, the loop ends.
To execute this modular program, you can simply call the `printNumbers()` function wherever you want to print the numbers:
```pseudo
// Call the printNumbers function
printNumbers();
```
This example demonstrates how modular programming allows you to encapsulate a specific task or logic (printing numbers) into a separate module (function), making the code easier to understand and maintain.
