Question $1[3$ mark$]$ Find the Smallest Number

Write a simple program that helps a user find the smallest positive number among

a limited series of positive integers entered by the user. The program should

perform the following tasks:

$1.$ Prompt the user to enter a series of positive integers: The program should

repeatedly prompt the user to enter up to $5$ positive integers, separated by

blanks. The user can enter no more than $5$ positive integers, and to indicate

the end of input, the user should enter $-1.$ The program will omit the integers

after $-1.$

$$ Wrong Condition $1$: If the user enters a non$-$positive integer

$($excluding $-1),$ display an error message and terminate the program.

The program should not consider negative integers.

$$ Example: $-2341-1$ Note: $-2$ is a non$-$positive integer before ending

$$ Example: $0341-1$ Note: $0$ is a non$-$positive integer before ending

$$ Example: $3-4-1$ Note: $-4$ is a non$-$positive integer before ending

$$ Example: $32-4-1$ Note: $-4$ is a non$-$positive integer before ending

$$ Example: $32-49-1$ Note: $-4$ is a non$-$positive integer before ending

For these examples, the program display:

$$ Wrong Condition $2$: If the user enters a non$-$integer value $($e$.$g$.,$ a

letter or a symbol$),$ display an error message and terminate the

program. The program should not consider this input.

$$ Example: $5$ B C $2-1$ Note: B is a non$-$integer value before ending

$$ Example: B $2-1$ Note: B is a non$-$integer value before ending

$$ Example: $ $14-1$ Note: $ is a non$-$integer value before ending

$$ Example: A $5$ B C $2-1$ Note: A is a non$-$integer value before ending

$$ Example: $5241$ & $-1$ Note: & is a non$-$integer value before ending

For these examples, the program display:

Error: Non$-$positive integer.

Thank you for using the program!

Error: Not ended with $-1.$

Thank you for using the program!

$$ Wrong Condition $3$: If the user only enters $-1$ or the first integer is $-$

$1,$ display an error message and terminate the program.

$$ Example: $-1$ Note: only enters $-1$

$$ Example: $-1253$ Note: the first integer is $-1$

For these two examples, the program display:

$$ Wrong Condition $4$: If the number of positive numbers is more than

$5$ before the ending $-1,$ display an error message and terminate the

program.

$$ Example:$654321-1$ Note: the number of positive numbers is

more than $5$ before the ending $-1.$

$$ Example: $34253423-1$ Note: the number of positive numbers is

more than $5$ before the ending $-1.$

For these two examples, the program display:

The program will only report the first error it meets.

$$ Example: $-2$ A $152025-1$ Note: the first error is non$-$positive integer.

For this example, the program display:

Error: Non$-$positive integer.

Thank you for using the program!

Error: Only $-1.$

Thank you for using the program!

Error: Non$-$integer value.

Thank you for using the program!

$2.$ Find the smallest positive number: After the user finishes entering feasible

numbers and enters $-1$ to stop, the program should determine the smallest

positive number from the entered values.

$3.$ Display the smallest positive number: The program should display the

smallest positive number to the user.

$4.$ Ask the user if they want to repeat the process: After displaying the

smallest positive number, the program should ask the user if they want to

find the smallest positive number again with a new series of positive

integers. If the user responds with $"$Y$",$ repeat the process. If the user

responds with $"$N$",$ end the program. Other responses, such "abc" and "aaa",

will also end the program $($Please refer to the Example $5$ below$).$

The examples have considered most cases for test. Please carefully read the

examples, which will help you to fully understand the above question.

Ensure that the program output follows the format of the following examples.

Otherwise, you will not pass the test.

For example, $$Enter up to $5$ positive integers, separated by blanks. To stop,

enter $-1$ and press Enter:$.$ You should not misspell any words. A good

strategy is to directly copy the sentence and use it in your program.

Example $1$

Enter up to $5$ positive integers, separated by blanks. To stop, enter $-1$ and press Enter:

$101520-1$

The smallest positive number is: $10$

Do you want to find the smallest positive number again? $($Y$/$N$)$:

Y

Enter up to $5$ positive integers, separated by blanks. To stop, enter $-1$ and press Enter:

$58121822-1$

The smallest positive number is: $5$

Do you want to find the smallest positive number again? $($Y$/$N$)$:

N

Thank you for using the program!

Example $2$

Example $3$

Example $4$

Example $5$

Example $6$

Enter up to $5$ positive integers, separated by blanks. To stop, enter $-1$ and press Enter:

$-1$

Error: Only $-1.$

Thank you for using the program!

Enter up to $5$ positive integers, separated by blanks. To stop, enter $-1$ and press Enter:

$17-1$

The smallest positive number is: $17$
