Question

Write an expression that executes the loop body as long as the user enters a non-negative number. note: these activities may test code with different test values. this activity will perform three tests, with usernum initially 9 and user input of 5, 2, -1, then with usernum initially 0 and user input of -17, then with usernum initially -1.

Answer 1

If( usernum >= 0 )
{
   /* do something */
}

Answer 2

For the given problem, prompts the user to enter a number and then while loop is used to check whether a number is positive or not. Under the while loop body statement is printed and then input is stored in the user value. Then print the statement as ‘Done’.

Further Explanation:

Code: Following is the python code to that executes the loop body as long as the user enters a non-negative number.

#Prompt and read the input from the user

user_num = int(input('Enter a number:'))

#Loop is used to repeat the values of number

while (user_num>=0):

# If user enters a positive number then display the body statement.

print('Body')

user_num = int(input())

# Display the output.  

print('Done.')
