If the number equals zero, output a message saying so. Otherwise, output a message stating that the number is negative. Submit your flowchart, a screen shot of the program, and a screen shot of the output when you run the program with the following inputs: -3, 0, +3 Program 3.b: Program Requirements: Prompt the user to enter a number. If the number is greater than or equal to zero, check to see if it equals zero. If it does output a message saying so. Otherwise, output a message saying that it is a positive number. If the number entered was not greater than or equal to zero, output a message saying that it is a negative number Submit your flowchart, a screen shot of the program and a screen shot of the output when you run the program with the following inputs: -3, 0, +3
