I need to write a tax calculation program in C for a store chain. There 4 stores and 4 different tax rates .0700, .0725, .07500 and .0775
This is what i have so far...
any suggestions
#include <stdio.h>
int main ()
{
char (a StoreLocation=0 )//Initialize variable for store
char b StoreLocation=1 ;
char c StoreLocation=2
char d StoreLocation=3
int iError = 0; // Error - improper entry indicator
int iRepeat; // function iteration control variable
char cContinue = 'y'; //Initialize variable continue program
float fTaxRateLH = .07750; // Tax Rate La Jolla
float fTaxRateEN = .07500; // Tax Rate Encinitas
float fTaxRateDM = .07250; // Tax Rate Del Mar
float fGrossReceipt=0 .00;//Initialize Gross Receipts
float fTotalTax=0.00; //Initialize variable for total taxes
// start loop for program execution
{ClrScr();//Clear the screen
StoreLocation = '0';// Set location to zero
printf ("\n\nThis program computes sales tax on sales at one or all Kudler Foods locations.\n\n" );//describe program
printf ("enter the number for the Kudler store location you need.\n\n"); // Display Ask for the store location - CR2
printf ("1 - DelMar\n");//selection 1 - CR2
printf ("2 - Encinitas\n");//selection 2 - CR2
printf ("3 - La Jolla\n");//selection 3 - CR2
printf ("4 - ALL\n");//selection 4 - CR2
printf ("\n\nLocati on? (1,2,3,4) ");//prompt - CR2
cStoreLocation = getch();//get the store location and continue - CR2
ClrScr();//Clear the screen
switch (cStoreLocation )//run routine for any or all stores - CR2
{case 49://if the location is Del Mar - CR2
printf ("\n\nYou picked the DelMar Kudler location, where");// output location selection
(fTaxRate = fTaxRateDM);//assign tax rate for Del Mar
iError = IndividualTaxes Owed (fTaxRate, fGrossReceipt, fTotalTax, iError);/*function finds taxes owed for this location
and sets error condition if input error is detected - CR1,2*/
//end case
case 50://if the location is Encinitas - CR2
printf ("\n\n They picked the Encinitas Kudler location, where")// output location selection

break;//end case

cStoreLocation = ("");// set location back to nothing
break;// End Default case
}//end switch
if (iError == 1)break; // Don't get another location if error is present
printf ("\nWould you like to try another Kudler location? Enter \"Y\" for yes ");//ask if the program is done
cContinue = getch();//get the answer
}//end do loop
while ( iError == 0 && (cContinue == 'y' || cContinue == 'Y'));//if no errors and continue program is (y)es, restart at selection
