Chapter 5: Problem 26

Write a nested loop that displays 10 rows of ' \(a^{\prime}\) characters. There should be \(15^{\circ} e^{\prime}\) characters in each row.

Short Answer

Expert verified

**Question**: Write a nested loop that will display 10 rows of 'a' characters, where each row should contain 15 'a' characters. **Answer**: Here's a nested loop in Python that achieves this: ```python for row in range(10): for column in range(15): print('a', end='') print() ```

Step by step solution

Identify the programming language

In this task, the programming language has not been specified. However, since the concept of nested loops is applicable in all programming languages, the example will be given in Python (which is widely used and easy to understand). If you need another language, the process remains almost the same.

Set up the outer loop

The outer loop will iterate through the rows. We know that there are 10 rows, so we can use a `for` loop to iterate 10 times. In Python, we can use `range(10)` for this purpose: ```python for row in range(10): ```

Set up the inner loop

Inside the outer loop, we will add another `for` loop to iterate through the columns. We know that there are 15 'a' characters in each row, so we can use `range(15)` for this purpose: ```python for row in range(10): for column in range(15): ```

Display the 'a' character

In Python, the `print()` function can be used to display any character or string. Therefore, inside the inner loop, we can use this function to print the 'a' character. By default, the `print()` function adds a newline at the end, so we should set the `end` parameter to an empty string: ```python for row in range(10): for column in range(15): print('a', end='') ```

Move to the next row

After each row of 'a' characters is printed, we need to move the cursor to the next line. To do this, we can add a `print()` statement outside of the inner loop but still inside the outer loop: ```python for row in range(10): for column in range(15): print('a', end='') print() ```

Final Code

Here is the complete code to display 10 rows of 'a' characters, with 15 'a' characters in each row using nested loops in Python: ```python for row in range(10): for column in range(15): print('a', end='') print() ```
