i need alil help with my switch question

never expect anyone to write a program for you in this forum, but since i see you've at least been trying i'll help you out.

Code:

#include <stdio.h> 

int main() 
{
  int swt=0, num1=0, num2=0, num3=0, num4=0, num5=0;
  float awn1=0, awn2=0, awn3=0, awn4=0, awn5=0, total;
 
  for(;;)  //infinite for statemtn basically a loop which never ends
  { 
    printf ("\nEnter the product number(-1 to end): "); 
    scanf ("%d", &swt );
    if(swt==-1)
      break;
  
    switch ( swt )
    { 
      case 1: 
        printf ("Enter the amount for No.1: "); 
        scanf ("%d",&num1 ); 
        awn1 = num1 * 2.98;
        break; 

      case 2: 
        printf ("Enter the amount for No.2: "); 
        scanf ("%d", &num2 ); 
        awn2 = num2 * 4.50; 
        break; 

      case 3: 
        printf ("Enter the amount for No.3: "); 
        scanf ("%d", &num3 ); 
        awn3 = num3 * 9.98; 
        break; 

      case 4: 
        printf ("Enter the amount for No.4: "); 
        scanf ("%d", &num4 ); 
        awn4 = num4 * 4.49; 
        break; 
      
      case 5: 
        printf ("Enter the amount for No.5: "); 
        scanf ("%d", &num5 ); 
        awn5 = num5 * 6.87; 
        break; 

      default: 
        printf ("Incorrect number\n"); 
        printf ("Enter your product number:"); 
    } 
  } 

  total = awn1+awn2+awn3+awn4+awn5; 
  printf ("\nThe total for you products is: %.2f",total); //total is float!
                //%.2f prints the floating point total with 2 decimal places
  getch(); 
  return 0; 
}

A cut down version, showing the switch statement.

Code:

#include <stdio.h>
#include <conio.h>

int main(void)
{
	int  num1;
	clrscr();

	printf("Enter choice, 1 or 2: (x to exit) ");
	while (scanf("%d", &num1) == 1)
	{
		switch (num1)
		{
			case 1:	
				printf("Doing stuff for 1\n");
				break;
			case 2:	
				printf("Doing stuff for 2\n");
				break;
			default:
				printf("Doing stuff for default (ie Not 1 or 2)\n");
				break;
		}
		printf("Enter choice, 1 or 2: (x to exit) ");
	}

	printf ("All done, press any key\n");
	getch();
	return(0);
}

lol i beat you by a fraction of a sec
