In this program i want to ask the cashier if the customer wants to buy anything else. Typically,

Ask customer what beef product he wants to buy.
Ex. 1 //Chicken Liver
Ask customer how many kilo(s) he will buy.
Ex. 2 //2kg

(problem)
Then ask the customer if he wants to buy another product. "y or n"
if y -->Then ask again the customer what beef product he wants.
if n --> proceed.

I still don't know to do that.
We haven't taught about it yet.

This is just a part of my very long code hehe...
@_@ im still a newbie.

#include <stdio.h>
#include <stdlib.h>

I made a rough algorithm from given program.

Take inputs from user.
Do calculations.
Print the result.

I suggest you to add do...while loop as follows =>

do
{

    //code

Then ask the customer if he wants to buy another product. "y or n"
if y -->Then ask again the customer what beef product he wants.
if n --> proceed.
//this prompt will be at very end inside this do....while loop
//this loop will repeat until customer says 'NO'.
   }while(condition);//dont forget this semicolon!!!
//if customer says 'NO' then you will come out of the loop here...
2. Do the calculations
3. Print result.
