Simple C program to convert Binary code to gray code

Code:

#include<stdio.h>
#include<conio.h>
void main()
{int a[10],i=0,c=0,n,b[10];
printf("\n enter the binary code");
scanf("%d",&n);
while(n!=0)
{a[i]=n%10;
n/=10;
i++;
c++;
}
for(i=c-1;i>=0;i--)
{
b[i]=a[i];
}
for(i=c-1;i>=0;i--)
{
if(b[i]==1)
{
if(a[i-1]==1)
a[i-1]=0;
else
a[i-1]=1;
}
}
printf("\n the gray code is");
for(i=c-1;i>=0;i--)
printf("%d",a[i]);
getch();
}

Simple Java program to Implement sorting algorithm using TCP on Server application Input: Give input on client side and client should receive sorted output from server and display sorted list on input(client) side. Note: You can implement any sorting algorithm by changing the sorting algorithm code on server side Code: Server: package aj.pkg7; import java.io.*; import java.net.*; import java.util.*; class Server { public static void main(String args[]) throws Exception { ServerSocket ss=new ServerSocket(1111); Socket s=ss.accept(); DataInputStream din=new DataInputStream(s.getInputStream()); DataOutputStream dout=new DataOutputStream(s.getOutputStream()); int r,i=0; int n=din.readInt(); int a[]=new int[n]; System.out.println("data:"); int count=0; for(i=0;i<n;i++) { a[i]=din.readInt(); } int number = a.length; for (int i1 = 0; i1 < number-1; i1++) for (int j1 = 0; j1 < number-i1-1; j1++) if (a[j1] > a[j1+1]) { int temp = a[j1]; a[j1] = a[j1+1]; a[j1+1] = temp; } ...
