Whats wrong with my program?

It compiles successfully but when I actually run the program an error comes up. I'm using Dev-C++.

Well, I got 5 errors in compilation:

cannot find conio.h
undefined: sinese1, sinese2, sinadd and tissue.

i commented out conio.c and declared the vars as globals. The program then proceeded to tell me that 3+4 was 0.

>cout << sinese1 << " + " << sinese2 << "= " << sinadd;

cout << sinese1 << " + " << sinese2 << "= " << sinese1+sinese2;

Code:

---


switch(mainresponse) {
 case 1:
  //do whatever
}

switch(mainresponse){
 case 2:
  //do whatever
}

---

should be condensed into

Code:

---


switch(mainresponse){
 case 1:
  //do whatever
  case 2:
    //do whatever
}

---

can someone revise it and e-mail it to me at [email protected]
