I was wondering if anyone could give me some help on this homework assignment. I have done all the tasks asks of me, but when I try to run the program to test it out, my IDE says the thread exits with a code 0 (whatever that means). I am almost sure I did everything correctly, I just need to be able to match it with the desired output. Here is the problem:
enter number 1: a
That is an invalid number, enter another number: 10
enter number 2: 20
enter number 3: 30
enter number 4; 40
enter number 5: 50
Table with the numbers in various bases
bin oct dec hex
1010 012 10 A
10100 024 20 14
11110 036 30 1E
101000 050 40 28
110010 062 50 32
Table of formatted and unformatted floating points
unformatted formatted
10 +1.00E+001
20 +2.00E+001
30 +3.00E+001
40 +4.00E+001
50 +5.00E+001
