Windows 8.1 Password Resolved

In daily use, we do not really prefer to always type a long password that we have for our live account. Instead, what we can do is, we can very easily alter it or you can say bypass it by applying the following procedure.

Click on the search in the right panel as shown in the figure below.

 

 

After you click on search, the following panel will open. Type password. Here you see, as highlighted in the figure below. Click on “Sign-in options”.

 

 

 

Now, here you have different options, the most suitable and easier way is to have a four digit pin.

Click, on the change button in the “PIN” option which is the third one here.

 

 

First it will prompt you to enter your Hotmail account password which you are using to log into your windows.

Enter your password. As i did mine in the following diagram.

 

 

 

Now, enter your four digit pin number.

 

 

Like this.

 

 

 

And here you go, now when you want to log into your windows you will just have to enter the pin and it logs in.

C program to print different Star Formations using For Loop

Here is the code to print different star formations using for loop.

#include "stdio.h" int main() {     int num,i,j,k,m,n,o,p;      printf("Please enter a number to print the star formations \n");      scanf("%d", &num);        for(i=0;i<num;i++)     {     for(j=0;j<num;j++)         {                 printf("*");         }                 printf("\n");     } printf("\n"); j=0,i=0,k=0; // Hollow Star formation     for(i=0;i<num;i++)     {     for(j=0;j<num;j++)         {             if(i==0 || i==num-1)             {                 printf("*");                }             else if(j==0 || j==num-1)             {                 printf("*");             }             else             {                 printf(" ");             }         }         printf("\n");     }      // downward descending formation      printf("\n");      j=0,i=0,k=0;      for(i=num;i>0;i--)         {             for(j=i;j>0;j--)             {                 printf("*");             }             printf("\n");         } printf("\n"); j=0,i=0,k=0;       for(i=num;i>=0;i--)         {             for(k=i;k<num;k++)             {             printf(" ");             }             for(j=0;j<=i-1;j++)             {                 printf("*");             }             printf("\n");         } printf("\n"); j=0,i=0,k=0; // Star formation right angle triangle.         for(i=num;i>0;i--)         {             for(j=0;j<i-1;j++)             {                 printf(" ");             }             for(k=j;k<num;k++)             {             printf("*");             }             printf("\n");         } printf("\n"); j=0,i=0,k=0;     for(i=0;i<num;i++)     {     for(j=0;j<=i;j++)         {                 printf("*");         }                 printf("\n");     }      return 0; }

The output of the above code is following:

C program to print the hollow stars square

Here is the code for the C program to print the star formation of a hollow square. The program will input an integer value from the user and print the hollow star formations.
Here is the code.

#include “stdio.h” int main() { int num,i,j; printf("Please enter a number to print the hollow star formation \n"); scanf("%d", &num); for(i=0;i<num;i++) { for(j=0;j<num;j++) { if(i==0 || i==num-1) { printf("*"); } else if(j==0 || j==num-1) { printf("*"); } else { printf(" "); // space is printed .. } } printf("\n"); } return 0; }

Here is the sample output.


As can be seen in the output above, for the user input, the hollow star square will be formed. The key to understand the logic of the code is as follows.
The outerloop controls the number of  lines and inner loop controls the number of stars.

C program to display integers in Ascending without using Loop

This program run sorts and display the integers in ascending order. It finds the largest and smallest integer values respectively.

First download the windows installer by writing following in google and open the first link.

Now, click on the Get the installer button.

C Program Phases Writing And Executing A Program

System Software
The system software controls the computer. It communicates with computer’s hardware (key board, mouse, modem, sound card etc) and controls different aspects of operations. Sub categories of system software are:

• Operating system
• Device drivers
• Utilities

Operating system

An operating system (sometimes abbreviated as "OS") is the program that manages all the other programs in a computer. It is a integrated collection of routines that service the sequencing and processing of programs by a computer. Note: An operating system may provide many services, such as resource allocation, scheduling, input/output control, and data management.

Device drivers

The device driver software is used to communicate between the devices and the computer. We have monitor, keyboard and mouse attached to almost all PC’s; if we look at the properties of these devices we will see that the operating system has installed special software to control these devices. This piece of software is called device driver software. When we attach a new device with the computer, we need software to communicate with this device. These kinds of software are known as device drivers e.g. CD Rom driver, Sound Card driver and Modem driver. Normally manufacturer of the device provide the device driver software with the device. For scanners to work properly with the computers we install the device driver of the scanner. Nowadays if you have seen a scanner, it comes with TWAIN Drivers. TWAIN stands for Technology Without An Interesting Name.

Installation of Dev C++

Here is the step by step procedure for the installation of Dev C++
First, download the Dev C++ from the following link.
