Hello again,

1) Explain briefly what the program does. Please see program code below.
2) Make a structure chart for the program code given, . (ILLUSTRATION) stating the flow of the program.
3) Revise a problem statement for the CODE.
4) Enumerate the functions used in the program. Briefly describe the purpose of the function.
5) What is the Output on the screen if you enter the following?
5.a. Enter Choice (1 or 2): 3
5.b. Enter Choice (1 or 2): 1
5.c. ****>Enter your integer: -72
5.d. ****>Enter your integer: 3
5.e. Do you want to continue? (y/n): y
5.f. Enter Choice (1 or 2): 2
5.g. ****>Enter beginning of range: -7
****>Enter end of range: 17
5.h. ****>Enter beginning of range: 1
****>Enter end of range: 10
5.i. Do you want to continue? (y/n): n
6) What is the over-all output on screen? You assume all inputs are correct. Show the output when you enter 1. And show the output when you enter 2. And ranges from 1 to 10.

Smells like homework/quiz to me. Sorry. Don't do others' homeworks. In any case, you should be able to compile and run this instead of asking. What prevents you from actually trying this out in a compiler?
