i am confuse about the rest of the calculation and how to display the total

**Hammer** · 09-15-2002

Compute the tax in simple maths terms... then printf the result with printf().

Something like
>printf ("Sale Amount: %f plus %f tax is %f\n", SaleAmount, Tax, SaleAmount+Tax);

There's somethings you'll need to learn about formatting of the output, but I'll let you find that out for yourself

Also, have a read of this.

Likely a bug filled masterpiece, but perhaps it *might* help.

Code:

#include <stdio.h>


int main(void)
{
   const float salesTax = 0.06;
   float prices[3] = { 3.99, 2.75, 1.35 };
   float subTotal, total;
   int selection;
	
   subTotal = 0.0;
   total = 0.0;
	
   printf("1> wrench $3.99\n");
   printf("2> socket $2.75\n");
   printf("3> wood   $1.35\n");
   printf("\n--> ");
	
   scanf("%d", &selection);
	
   subTotal = prices[selection - 1];
	
   total = (subTotal * salesTax) + subTotal;
	
   printf("\nFor item purchased, you owe %.2f\n", total);
	
	
   return 0;
}

Of course you'd have to check it for data input that is out of range.

In the future please use code tags when posting code. I added them for you this time. People are MUCH more likely to help you if you use them.

Kermi, that link you posted is broken.
