1.Design the logic for a program that allows the user to enter 10 numbers, then displays them in the reverse order of their entry. 2.Modify the reverse display program so that the user can enter up to 10 numbers until a sentinel value is entered.

Answer

To design the logic for the first program, where the user enters 10 numbers and then the program displays them in reverse order, we can follow these steps:

1. Initialize an array of size 10 to store the entered numbers.
2. Create a loop that iterates 10 times, allowing the user to input a number in each iteration and storing it in the array.
3. After the loop, create another loop that starts from the last element of the array and iterates down to the first element.
4. Inside this loop, display each number from the array.
5. End the program.

Here is the logic for the above program in a pseudo-code format:

1. Initialize an array of size 10.
2. Create a loop that iterates 10 times:
a. Prompt the user to enter a number.
b. Read the number and store it in the array at the current index.
3. Create a loop that starts from the last index and goes down to the first index:
a. Display the number at the current index.
4. End the program.

Now, let’s move on to modifying the program to allow the user to enter numbers until a sentinel value is entered. The sentinel value will act as a signal to stop entering numbers. We can follow these steps:

1. Initialize an array of size 10 to store the entered numbers.
2. Create a loop that iterates until the sentinel value is entered:
a. Prompt the user to enter a number.
b. Read the number and check if it is the sentinel value. If it is, break the loop.
c. Store the entered number in the array.
3. After the loop, create another loop that starts from the last element of the array and iterates down to the first element.
4. Inside this loop, display each number from the array.
5. End the program.

Here is the logic for the modified program in a pseudo-code format:

1. Initialize an array of size 10.
2. Create a loop that iterates until the sentinel value is entered:
a. Prompt the user to enter a number.
b. Read the number and check if it is the sentinel value.
i. If it is, break the loop.
ii. If it is not, store the entered number in the array at the current index and increment the index.
3. Create a loop that starts from the last index and goes down to the first index:
a. Display the number at the current index.
4. End the program.

By following these logical steps, you can design and modify the program as required to achieve the desired functionality.
