Requirements:

• The program must accept positive and negative numbers in its input sequence, and ?nd the largest and smallest

of the numbers entered whether they are all positive, all negative, or a combination of both positive and negative.

• Entering 0 must terminate the input sequence and cause the result to be displayed.
• If the ?rst number entered is zero, then the input sequence is empty and a message stating this must be

displayed (as shown in the sample run below) instead of showing the largest and smallest numbers.

• Name the source ?le for your program program2.c
• The prompts and output displayed by the program must be formated as shown in the sample run below (e.g.

blank lines, spacing, case of text).

• A sample run of the program with only positive numbers:

Entering 0 will terminate the sequence of input values.

Enter a number: 9

Enter a number: 5.2

Enter a number: 44

Enter a number: 0

Your largest number was 44.000. Your smallest number was 5.200.

• A sample run of the program with only negative numbers:

Entering 0 will terminate the sequence of input values.

Enter a number: -4

Enter a number: -38

Enter a number: -5.6

Enter a number: 0

Your largest number was -4.000. Your smallest number was -38.000.

• A sample run of the program with both positive and negative numbers:

Entering 0 will terminate the sequence of input values.

Enter a number: 6

Enter a number: 78

Enter a number: -3

Enter a number: 0

Your largest number was 78.000. Your smallest number was -3.000.

• A sample run of the program with an empty input sequence:

Entering 0 will terminate the sequence of input values.

Enter a number: 0

Your input sequence was empty.Hints:

• How will you keep track of whether or not any numbers have been entered? Think about what variables you

need.

• What needs to be done di?erently when the ?rst number is read compared to when later numbers are read?
• Are the above two items related?
