I am missing something here, it works but it is buggy, like the enter speed of 40 and hours of 30, its suppose to print
1 40 40
2 40 80
3 40 120

but its buggy and i am only getting the first 2 hour and not the 3rd, any idea where the code is buggy at.

nevernmind i found the bug.

while (a != hours)

is suppose to be

while (a <= hours)
