Building arrays to hold letters and guesses

$letters = array('a','b','c','d','e','f','g','h','i','j','k','l','m','n','o',
'p','q','r','s','t','u','v','w','x','y','z');
$right = array_fill_keys($letters, '.');
$wrong = array();

FACTORIAL OF A NUMBER USING RMI IN JAVA

CLIENT PROGRAM: import java.io.*; import java.rmi.*; public class client { public static void main(String args[])throws Exception { try { String s="rmi://"+args[0]+"/abc"; serverint f=(serverint)Naming.lookup(s); DataInputStream m=new DataInputStream(System.in); int n1=Integer.parseInt(m.readLine()); System.out.println("the factorial is"+f.fact(n1)); } catch(Exception e) { System.out.println(e); } } } INTERFACE PROGRAM: import java.rmi.*; public interface serverint extends Remote { int fact(int n)throws Exception; } IMPLEMENTATION PROGRAM: import java.rmi.*; import java.rmi.server.*; public class serverimpl extends UnicastRemoteObject implements serverint { public serverimpl()throws Exception { } public int fact(int n) { int i,c=1; for(i=1;i<=n;i++) { c=i*c; } ret...

CREATE A PYRAMID PROGRAM IN C

#include<stdio.h> #include<conio.h> void main() { int row, c, n, temp; printf("Enter the number of rows in pyramid of stars you wish to see "); scanf("%d",&n); temp = n; for ( row = 1 ; row <= n ; row++ ) { for ( c = 1 ; c < temp ; c++ ) printf(" "); temp--; for ( c = 1 ; c <= 2*row - 1 ; c++ ) printf("$"); printf("\n"); } getch(); } OUTPUT: Enter the number of rows in pyramid of stars you wish to see: 5 $ $$$ $$$$$ $$$$$$$ $$$$$$$$$

Write a c program or code to subtract two numbers without using subtraction operator #include <stdio.h> int main(){ int a,b; int sum; printf( "Enter any two integers: " ); scanf( "%d%d" ,&a,&b); sum = a + ~b + 1; printf( "Difference of two integers: %d" ,sum); return 0; } Sample Output: Enter any two integers: 5 4 Difference of two integers: 1
