Question

What is a count-controlled loop?

Short answer

Answer: A count-controlled loop is a programming concept where a loop iterates a specific number of times based on a predefined count. In Python, you can create a count-controlled loop using a for loop. To create one, follow these steps: 1. Set the iteration range using the built-in range() function, e.g., range(1, 6) for numbers 1 to 5. 2. Create the for loop using the syntax `for i in range(1, 6):`, where `i` is the variable holding the current iteration number. 3. Write the code to be executed inside the loop, such as using the print() function to print the current number `i`. 4. Run the code. The loop will iterate through the specified range and execute the code inside the loop for each iteration.

Step-by-step solution

Definition of a count-controlled loop

A count-controlled loop is a programming concept where a loop iterates a specific number of times based on a predefined count. Typically, such a loop uses a counter variable to hold the current iteration number and keep track of the iterations.

Example of a count-controlled loop

One of the simplest and most common examples of a count-controlled loop is a for loop in Python. In this example, we want to print the numbers from 1 to 5.

Set the iteration range

First, we need to set the range of numbers that the loop will iterate through. In Python, we can use the built-in range() function to generate a sequence of numbers. In this example, we want to loop through the numbers 1 to 5, so we will use the function range(1, 6), which generates a sequence of numbers from 1 to 5.

Create the for loop

Now that we have the range of numbers to iterate through, we can create a for loop that iterates over this range. Here's the code for the for loop: ``` for i in range(1, 6): ``` Here, `i` is a variable that will hold the current number in the iteration at each step. The for loop will loop from 1 to 5.

Write the code inside the loop

Inside the loop, we want to print the current number `i`. To do this, we can use the print() function in Python as follows: ``` for i in range(1, 6): print(i) ```

Run the code

When you run the code, the for loop iterates through the numbers 1 to 5, and the print() function prints each number on a separate line: ``` 1 2 3 4 5 ```
