Storing input values while iterating

Hello again!


I am having a hard time dealing with my machine problem. The problem requires me to create a program that will enable the user to input the number of employees of a certain company. After that, the program must ask the user to input the data of each employee(Employee Number, Hours of Work, and Employee type--permanent or temporary). It will do the loop until all of the employees' data are stored. Then the program must compute for their salaries and display it on the screen in table format.

Okay, this is the trick. We are now allowed to use iterative functions and function calls. My problem now is how can i store the values in variables for the data of each employee. The maximum number of employees is 20. And we are not allowed to use arrays, strings, pointers, structs and the likes.

Another problem would be how can i print the table out?

Thanks for the people who replied on my last post, especially "mats". :D

I hope you can help me with this.

Um, you sure that is really what the requirements are? It seems a little restrictive.

And this is supposed to teach you what - frustration?

This is the kind of code real noobs come up with before they learn about arrays and loops. But if you already know these things, then this seems a pointless exercise from a bone-head of a tutor.

Since you can't use arrays, and presumably malloc(), your only choice of container is the program stack; i.e. you must use recursion. This has the unfortunate drawback is that this means that the results will come out in reverse order of the input. But besides that it is strait forward.

Basically you need to write a function with the following structure:

Code:

---

void func(int numEmployees){
    Data data;
    if(numEmployees==0)
        return;
    data = getEmployeeData();
    func(numEmployees-1);
    printSalary(data);
}

Print before you make the recursive call to change that:

Example:

Code:

---

void func(int numEmployees){
    Data data;
    if(numEmployees==0)
        return;
    data = getEmployeeData();
    printSalary(data);
    func(numEmployees-1);
}

Yes it would, but russel1013 said "It will do the loop until all of the employees' data are stored. Then the program must compute for their salaries and display it on the screen in table format." This indicates that the employees data must all be stored before the results are printed. Your solution would not satisfy this.

Without that requirement, there is no point in using recursion, since you do not actually need to store the data for each employee after you print the result. Just iterate through each element, getting the data, print the result, then write over the data with the next iteration.

Very good point. I think his assignment sucks.

Well actually King Mir is right.

Well I am not allowed to use stacks, because it has not been taught to us yet.

Either you got your assigment all confused or your professor is an idiot.

Ok!

Thanks for all the comments about the problem and my teacher. I got a solution to this machine problem...

Can you post it here, so we all share in the joy? :D
