My menu program won't stop looping

Please help me I am an absolute begginner. I am writing a program that allows a user to enter options 1 to 5 on a menu. The choice they make has to be an integer. I have an no problems yet my problem starts when a letter is keyed in my program goes into a loop. Please can someone help me with the code i need to stop this happening. I am sorry if i have not described what is happening to clearly i am still learning the correct terminology. This program is part of my HNC in computing so i'm dead if i don't get it sorted thanks

Yes - I detect telepathically that you don't increment your loop variable.

What about if you wrote some code, that we (programmers) could help you.

Let me guess, your code looks like this....

Code:

---

for (;;)
{
 scanf ("%d", &i);
 switch (i)
 {
  case 1:
  // stuff
  break;
  case 2:
  // stuff
  break;
  case 3:
  // stuff
  break;
  case 4:
  // stuff
  break;
  case 5:
  // stuff
  break;
  default:
  break;
 } // end switch
} // end for

---

Just flush the input buffer after your scanf...

Code:

---

for (;;)
{
 scanf ("%d", &i);
 for (; cetchar () != '\n';);
 switch (i)
 {
// ...

---

It's not the best solution in the world, but it works.
