Simple C program to convert Octal number to Decimal Number

Code:

#include <stdio.h>
#include<conio.h>
#include <math.h>

int main()
{
long long octal, tempOctal, decimal;
int rem, place;
printf("Enter any octal number: ");
scanf("%lld", &octal);
tempOctal = octal;
decimal = 0;
place = 0;

while(tempOctal!=0)
{
rem = tempOctal % 10;
decimal += pow(8, place) * rem;
tempOctal /= 10;

place++;
}

printf("\nOctal number = %lld\n", octal);
printf("Decimal number = %lld", decimal);

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; } ...
