Assistance in writing program
Is there a way to get assistance from other members in writing a program that deals with stock control?
Thats a bad way to ask a question; its very ambiguous. You won't get help asking that way.
Post some code, make clear your wants.

I have but its not the syntax errors that are the prolem right now. I need to add data structures and functions etc. Problem is i dont really know how to. That's why im asking for some help.
Create some abstraction, divide your variables in 3 structures, stock, product, order, after that, create some functions to compute an order, stock operations, display lists of products available, etc. and make a nice menu for your application.

I am one that thinks that whoever thought up the concept of percentage did so after getting repeatedly hit in the head.
Why are you multiplying by 10/100? Why not by 100/1000 or 1000/10000? Or by .1, which is the second most straightforward way? The most straightforward way is dividing by 10, just like the most straightforward way of saying "the 5% of x" is "x divided by 20".
Programmers never use percentages except for dealing with users. If we need to represent a fraction of something, 1 will be the whole, .5 the half, .25 the quarter, and so on. Likewise, 1.1 will be "the whole and one tenth".

so the division is no longer the problem now. can someone tell me how to put in a yes/no selection and get the program to terminate if the answer is no, or continue if yes, then end when the "yes" condition is finished?

Use a simple string conditional.

case 3:
char ans;
printf("Quantity on order OUT OF STOCK, do you want to continue y/n?");
scanf("%s", &ans);
if (ans=='y')
{
gross_total=quantity_on_order*product_price;
if (order_num<=10)
discount_amount=gross_total*10/100;
else
discount_amount=gross_total*5/100;
net_total=gross_total-discount_amount;
printf("Enter the amount of cash received\n");
scanf("%f", &cash);

printf("RECIEPT\n");

else
printf("Thank you for visiting MORE DISCOUNTS SPORTS STORE,");

break;
why does the else part print if i chose no?

Thats what you've asked it to do.
If you don't want anything to happen when you choose 'no' add something like:
which will do nothing.
if (ans=='y') will do the blocks that follow then anything other than 'y' will print the else part.If you don't want anything to happen when you choose 'no' add something like:
else if(ans=='no') {}which will do nothing.
