You posted this program a couple of weeks ago and got lots
of advice. But you seem to have ignored most of this advice.
Here it is again:
1) x1, x2, R, I, S should be "double", not "float"
2) You MUST check the return value of scanf() and take appropriate
action if it is wrong
3) Don't do any casting (eg. in the line "x1 = (float)FOO")
4) The "return 0" goes AFTER the "else" block, not inside it.
Hint: If you printf the result of your scanf("%c") using
%d, you might understand what is going on.
