Question

Please construct a program that runs as a counter: the program keeps asking users to enter a command. If the command is '+', it increases the counter by one; if the command is '-', it decreases the counter by one; and if the command is 'q', it stops asking input and prints out the total count. The following is an example of how the program would run: Total count is 2 The program is initialized as below count = 0 count -= 1 print('Total count is {}'. elif input_sign == '-': elif input_sign == 'q': count += 1 while input() != 'q': input_sign = input() while input_sign == 'q': while input_sign != '+': input_sign = input() input_sign = input() if input_sign == '+': while input_sign != 'q':

Answer 1

1. input_sign = input()
2. while input_sign != 'q' :
3. if input_sign == '+' :
4. count += 1
5. elif input_sign == '-'
6. count -= 1
7. input_sign = input()
8. print( 'Total count is {}.')

The code abovde will be the sequence. Explanation:

input:

+

-

q

initially count = 0

now if input_sign == '+'

then while(input_sign != 'q') is true

enter into the loop

if(input_sign == '+') is true

count = count+1 = 0+1 = 1

now if input_sign == '-'

then while(input_sign != 'q') is true

enter into the loop

if(input_sign == '+') is false

elif( input_sigb =='-') is true

count = count -1 = 1-1 =0

now if input_sign == 'q'

then while(input_sign != 'q') is false

come out of the loop

and print Total count is 0
