How to copy text in CMD?

Most of us are aware that in CMD (Command Prompt) paste is achieved by a right click. Then what about copying something from CMD itself. It is obvious that this is not possible by a CTRL+C command as it is for terminating a process in CMD. So lets learn how to do this!

• Open CMD just by typing cmd in search
• Then right click at title bar as shown in figure
  
• Go to properties and find edit options. 
• Check on the Quick Edit Mode option and click OK.
  
• Over!!! Now select the text you want to copy as you would do in any other text editor and right click on it. Paste it in your text editor! Simple!!
  

Note that you can't select text in CMD without checking on the Quick Edit Mode option!

C++ program to output alternate letters and numbers for a given input string

This program's aim is :

• when user inputs: abcd7123, output should be: a7b1c2d3.
• if no.of letters are more than numbers or vice verse then remaining substring of greater string should be followed. eg: if i/p=abc12345 then o/p=a1b2c345 or if i/p=abcd12 then o/p=a1b2cd

  1 #include<iostream> 
  2 #include<ctype.h>

A Simple C++ program based on strings

Aim of this program is...when a user gives input consisting of letters followed by numbers...eg: a2b3 then output should be aabbb

  1 #include<iostream> 
  2 #include<ctype.h> 
  3 using namespace std;
  4 int main() 
  5 { 
  6     char str[50],a;
  7     cout<<"Enter a string: "; 
  8     cin>>str; 
  9     int len=strlen(str),rep,j=0; 
 10     int i=len/2;
 11      
 12     while(i) 
 13     { 
 14          
 15         a=str[j]; 
 16         rep=(str[j+1])-'0'; 
 17          
 18         while(rep)

Guess the number game in PYTHON!!

Well, we love to guess and we feel happy if our guess is right.
This game is based on your guess. Computer randomly selects a number and you have to guess the number.
Simple!! Isn't it?? But you are give limited chances based on your range. So test your intuition with this game!!!
This game is written in python and output of the program will be as shown in figure:

The program is as follows:

import simplegui
import random
secret_number=0
secret_number1=0
secret_number2=0
remaining_100=0
remaining_1000=0
remaining=0
def new_game():
    global secret_number1,secret_number2,remaining_100,remaining_1000
    secret_number1=random.randrange(0,100)
    secret_number2=random.randrange(0,1000)
    remaining_100=7
    remaining_1000=10

def range100():
    
    global secret_number1,secret_number2,remaining_100,remaining,secret_number 
    new_game()
    secret_number=secret_number1
    remaining=remaining_100
    
def range1000():
   
    global secret_number1,secret_number2,remaining,remaining_1000,secret_number 
    new_game()
    secret_number=secret_number2
    remaining=remaining_1000
    
    
def input_guess(guess):
    global remaining,secret_number
    
    remaining=remaining - 1
    if(secret_number>int(guess)):
        print "Guess was: ",int(guess)
        print "No.of remaining choices: ",remaining
        print "Higher!!"
        
    elif(secret_number<int(guess)):
        print "Guess was: ",int(guess)
        print "No.of remaining choices: ",remaining
        print "Lower!!"
    else:
        print "Your guess was: ",int(guess)
        print "You win!!!"
    if(remaining==0):
        print "You lose!!"
        
        
frame=simplegui.create_frame("Guess the number!!!",300,300)
frame.add_input("Enter the guess",input_guess,150)
frame.add_button("Range of 0-100",range100,150)
frame.add_button("Range of 0-1000",range1000,150)
frame.start()

Rock-Paper-Scissor-Lizard-Spock game in PYTHON

The key idea of this game is as follows:
It's very simple:

1. Scissors cuts paper
2. Paper covers rock
3. Rock crushes lizard
4. Lizard poisons Spock
5. Spock smashes scissors
6. Scissors decapitates lizard
7. Lizard eats paper
8. Paper disproves Spock
9. Spock vaporizes rock
10. Rock crushes scissors

The program is as follows:

# Rock-paper-scissors-lizard-Spock template


# The key idea of this program is to equate the strings
# "rock", "paper", "scissors", "lizard", "Spock" to numbers
# as follows:
#
# 0 - rock
# 1 - Spock
# 2 - paper
# 3 - lizard
# 4 - scissors

    # print out the message for computer's choice
    print "Computer's choice: " , comp_choice
    # compute difference of comp_number and player_number modulo five
    
    result=(comp_number-player_number)%5

Playing with zeroes in matrices

It is one of the simplest tasks in C++. If an element in a matrix is found to be zero, then make its corresponding row and column to zeroes. Here is the code for the above task.

  1 #include<iostream> 
  2 using namespace std;
  3 class matrix 
  4 { 
  5     int a[50][50]; 
  6     int n,m; 
  7 public: 
  8     matrix(int rows,int cols) 
  9     { 
 10         n=cols; 
 11         m=rows; 
 12         **a=0; 
 13     } 
 14     void create() 
 15     { 
 16         cout<<"Enter elements: "; 
 17         for(int i=0;i<m;i++)
