1. Create a simple POS program that will compute the quantity order by the customer of a food store. Kindly refer to the sample output below:

#include<stdio.h>
#include<conio.h>
#define s scanf
#define p printf



int main()
{
     int q, total, choice, b, h, c, spag, cash, ch;
    char ans;
    p("*************************************");

    p("\n*************************************");
    p("\n*    Value Meal             Price   *");
    p("\n*************************************");
    p("\n* 1 - Burger, Fries w/Drinks    59  *");
    p("\n* 2 - Hotdog w/Drinks           59  *");
    p("\n* 3 - 1pc Chicken w/Drinks      89  *");
    p("\n* 4 - 2pc Chicken w/Drinks      125 *");
    p("\n* 5 - Spaghetti w/Drinks        59  *");
    p("\n*************************************");
