Design a code converter circuit to convert BCD to 8 4 -2 -1. Analyze the circuit output for the don’t care inputs. code example

Example 1: Given a double-precision number, , denoting an amount of money, use the NumberFormat class' getCurrencyInstance method to convert into the US, Indian, Chinese, and French currency formats

import java.util.Scanner;
import java.text.NumberFormat;
import java.util.Locale;

public class Solution {
    
    public static void main(String[] args) {
        /* Read input */
        Scanner scanner = new Scanner(System.in);
        double payment = scanner.nextDouble();
        scanner.close();

        /* Create custom Locale for India. 
          I used the "IANA Language Subtag Registry" to find India's country code */
        Locale indiaLocale = new Locale("en", "IN");

        /* Create NumberFormats using Locales */
        NumberFormat us     = NumberFormat.getCurrencyInstance(Locale.US);
        NumberFormat india  = NumberFormat.getCurrencyInstance(indiaLocale);
        NumberFormat china  = NumberFormat.getCurrencyInstance(Locale.CHINA);
        NumberFormat france = NumberFormat.getCurrencyInstance(Locale.FRANCE);

        /* Print output */        
        System.out.println("US: "     + us.format(payment));
        System.out.println("India: "  + india.format(payment));
        System.out.println("China: "  + china.format(payment));
        System.out.println("France: " + france.format(payment));
    }
}

Example 2: implement the Beizer Curve code in c

#include<graphics.h>
#include<math.h>
#include<conio.h>
#include<stdio.h>
void main()
{
int x[4],y[4],i;
double put_x,put_y,t;
int gr=DETECT,gm;
initgraph(&gr,&gm,"C:\\TURBOC3\\BGI");
printf("\n****** Bezier Curve ***********");
printf("\n Please enter x and y coordinates ");
for(i=0;i<4;i++)                 
{
scanf("%d%d",&x[i],&y[i]);
putpixel(x[i],y[i],3);                // Control Points
}

for(t=0.0;t<=1.0;t=t+0.001)             // t always lies between 0 and 1
{
put_x = pow(1-t,3)*x[0] + 3*t*pow(1-t,2)*x[1] + 3*t*t*(1-t)*x[2] + pow(t,3)*x[3]; // Formula to draw curve
put_y =  pow(1-t,3)*y[0] + 3*t*pow(1-t,2)*y[1] + 3*t*t*(1-t)*y[2] + pow(t,3)*y[3];
putpixel(put_x,put_y, WHITE);            // putting pixel 
}
getch();
closegraph();
}
