Switch statement problems

I am writing a program which incorprates a switch statement. I am having problem withs with the menu function.

say you are prompting the user to input some value. Let's call this this case one. Inside the menu function on the program how do you tell the computer to go get case one.

For instance I am trying.

printf("Input leg1:",case 1);

This isnt working at all. Any ideas.

You read the value into a variable, then use the switch on the variable.

Code:

float leg1 = -1.0, leg2 = -1.0, hypotenuse = -1.0, area = 0;
 

  case '1' :
 44                         {
 45                                 printf("Enter leg1: ");
 46                                 scanf("%f", &leg1);
 47                                 while(leg1 <= 0)
 48                                 {
 49                                         printf("Please enter a positive number: ");
 50                                         scanf("%f", &leg1);
 51                                 }
 52                         }
 53                         break;


Menu Printing Function;
219 void printMenu()
220 
221 {
222 
223 
224   printf("Input value for leg1:",case '1');
225   printf("Input value for leg2:");
226   printf("Input value for hypotenuse:");
227   printf("Calculate leg1:");
228   printf("Calculate leg2:");
229   printf("Calculate hypotenuse:");
230   printf("Calculate area of right triangle:");
214 }
215

What do you mean by that?

In C please? I don't understand what you said.

Code:

int input;
printf("Enter your choice (0 - exit, 1 - do something usefull):");
flush(stdout);
if( scanf("%d",&input) == 1)
{
   switch(input)
   {
      case 0: return 0;
      case 1:
         /* do something useful */
         break;
      default:
         /* wrong input - do something stupid */
   }
}
else
{
   /* wrong input - clear the stdin and try again */
}

Code:

flush(stdout);

fflush(), of course.

BTW -- "usefull" has one 'L' . . . .

Code:

/* wrong input - clear the stdin and try again */

Here's one way to do that:

Code:

while(getchar() != '\n');
