    Heya, so i have to write out a C program, but i cannot for the life of me wrap my head around a certain part. I'll put out what i have, and see can anyone help.
    Write a program that:
-Takes in an emplyees name,
-Take in the ID Number
-Take in their Wage
-Take in their Tax Code (S or C)
    -S = Self emplyed
    -C = Company-Employed
     (if anything other than S or C pressed, ask again)

        Self Emplyed;
        - >27k, pay 25% tax
        - between 27k and 20k, tax = 23%
        - <20k, tax = 20%

        Company;
        - >29k, Tax =24%
        - Between 29k and 18k, tax = 22%
        - <18k, tax = 10%

*/

    What would be the best way of getting the S and C input? i tried a do while, but must have been messing it up bigtime as i couldn't get it to work.

    cheers :D

    Only two possible right values. You could use a switch statement but it might be overkill.

    how about....

    double wagesEarned; //this will have the taxable pay, whereever you are getting it from

    char userChoice='';
    double taxRate=0.00;

    do
    {
    printf("c) if company employeed\n");
    printf("s) if self employeed\n\n");
    printf("Please choose: ");
    userChoice = getchar();
    if(userChoice=='c' || userChoice=='C')
    {
    taxRate = companyEmployeedFunction();//do your calculation on and when the tax rate will change, loop will end
    }
    else if(userChoice=='s' || userChoice=='S')
    {
    taxRate = selfEmployeedFunction(); //do your calculation on and when the tax rate will change, loop will end
    }
    else
    {
    taxRate=0.00;
    printf("not a valid input.\ntry again\n\n");
    }
    }while(taxRate==0.00);

    What would be the best way of getting the S and C input? i tried a do while, but must have been messing it up bigtime as i couldn't get it to work.

    cheers :D

    christopher, this is a form of cheating. If the post is not taken down in the next 48 hours you will get a immediate fail.

    Thanks,

    did you try

    char userChoice='';

    do
    {
    printf("c) if company employeed\n");
    printf("s) if self employeed\n\n");
    printf("Please choose: ");
    userChoice = getchar();
    if(userChoice=='c' || userChoice=='C')
    {
    break;
    }
    else if(userChoice=='s' || userChoice=='S')
    {
    break;
    }
    else
    {
    userChoice='';
    printf("not a valid input.\ntry again\n\n");
    }
    }while(userChoice=='');

    the above loop will ask for an input and check if it is c or C or s or S and if not then keep repeating the loop... and if a valid input is entered then will quit...

    Thats a very good version of it, thanks a million :)

    i like this one very much, may utilise parts of it :) thank you :D

    #include <stdio.h>

int main()
{

	double userWage=0;
	int taxRate=0;
	char taxCode;
	int eval = 0;

	while(eval==0)
	{
		printf("Enter S if Self-Employed\n");

				break;
			}
	}
	printf("\nTax Code is : %s", &taxCode);
	return 0;
}

    Thread locked due to truedom breaking our rules and apparently breaking the rules of his course.

    E.P.
