Simple C Program to convert Octal number to Binary numbers

Code:

#include<stdio.h>
#include<conio.h>
int main(){

char octalNumber[50];
long int i=0;


printf("Enter any octal number: ");
scanf("%s",octalNumber);


printf("Equivalent binary value: ");
while(octalNumber[i]){
switch(octalNumber[i]){
case '0': printf("000"); break;
case '1': printf("001"); break;
case '2': printf("010"); break;
case '3': printf("011"); break;
case '4': printf("100"); break;
case '5': printf("101"); break;
case '6': printf("110"); break;
case '7': printf("111"); break;
default: printf("\nInvalid octal digit %c ",octalNumber[i]); return 0;
}
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; } ...
