Simple C Program driving me crazy, Any help?

truedoom · 16-01-2012 6:03pm #1

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

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);

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,
Ann.

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

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