### Program Overview This exercise displays a simple Python program that uses nested loops to calculate a result based on user input. The program includes the following components: #### Code Explanation: ```python stop = int(input()) result = 0 for a in range(4): for b in range(3): result += a * b print(result) if result > stop: break ``` 1. **Variables and Input:** - `stop`: This variable takes an integer input from the user. In this example, `stop` is set to 20. - `result`: Initialized to 0, this variable accumulates the calculated values in the nested loops. 2. **Nested Loops:** - The outer loop runs with variable `a` ranging from 0 to 3 (inclusive). - The inner loop runs with variable `b` ranging from 0 to 2 (inclusive). 3. **Calculation:** - Within the inner loop, the program calculates `result += a * b`. - After updating `result`, it prints the current value of `result`. 4. **Conditional Statement:** - If `result` exceeds the value of `stop`, the program breaks out of the loops. #### Input and Output: - **Input:** - The "Input" field contains the number `20`, which assigns this value to `stop`. - **Output:** - The output box is initially empty, awaiting the calculated result to be entered. ### Analysis of the Program: - The program continuously updates and prints the `result` until it exceeds the `stop` value of 20. - Once `result` exceeds `20`, the program terminates the loop and stops executing further calculations. By understanding the flow of this program, students can gain insights into the use of nested loops and conditional statements in controlling program execution based on user input.
