Rearrange System Tray Icons

You can rearrange icons on the taskbar as you wish and start new (or switch to running) instances of the first ten taskbar programs using Win+1, Win+2, and so on. The cool thing is you can also rearrange system tray icons. Reorder them on the tray or move them outside or back in the tray. Take control of what you want to always keep an eye on, and from which apps you’ll require notifications.

Use Keyboard Shortcuts

Using the mouse, you can drag-‘n-dock windows to either side of the screen, or drag it to the top to maximize it. These keyboard shortcuts are even faster:

* Win+Left Arrow and Win+Right Arrow dock the window to the left and right side of the screen
* Win+Up Arrow and Win+Down Arrow maximize and restore/minimize
* Win+M minimizes everything
* Alt+Up, Alt+Left Arrow, Alt+Right Arrow navigate to parent folder, or browse Back and Forward through folders in Explorer
* Win+Home minimizes/restores all open windows except the active window
* Alt+Win+# accesses the Jump List of program number ‘#’ on the taskbar

Shake your desktop free of clutter

If you frequently run multiple programs simultaneously, your desktop can get extremely cluttered. This can get annoying if you're working on one program and want to minimize all the other windows -- in previous versions of Windows you had to minimize them individually.

With Windows 7's "shake" feature, though, you can minimize every window except the one in which you're currently working -- in a single step. Click and hold the title bar of the window you want to keep on the desktop; while still holding the title bar, shake it quickly back and forth until all of the other windows minimize to the taskbar. Then let go. To make them return, shake the title bar again.

You can accomplish the same thing by pressing the Window key-Home key combination -- although doing that is not nearly as much fun.

Moving pointer without using Mouse

Press Alt+Left Shift+Num Lock all at once and a prompt will appear telling you that you have activated mousekeys, select ok then you can control the mouse with the numpad.

The controls are:
1,2,3,4,6,7,8,9 = move the mouse
5 = mouse button click
+ = double click
insert = hold down mouse button
delete = release mouse button (after holding it down with insert)
/, * or – = select which mouse button the above controls will click (left, both or right respectively)
numlock = disable mousekeys

Use of pointers in C

#include
#include
void main()
{
int a[10],i,n,*p;
printf("Enter limit");
scanf("%d",&n);
printf("\nEnter elements");
for(i=1;i{
scanf('%d",*a[i]);
}
p=a;
for(i=0;i{
printf("%d",*(p+i));
}
getch();
}

C Program to fing largest number in array

#include
#include
void main()
{
int i,n,a[10],l;
clrscr();
printf("Enter limit of array");
scanf("%d",&n);
printf("Enter array elements");
for(i=1;i<=n;i++)
{
printf("\na[%d]=",i);
scanf("%d",&a[i]);
}
l=a[1];
for(i=1;i<=n;i++)
{
if(a[i]>l)
{
l=a[i];
}
}
printf("Largest no.=%d",l);
getch();
}

C Program insert items in arrary

#include
#include
void main()
{
int a[20],n,i,p,e;
clrscr();
printf("Enter limit of array");
scanf("%d",&n);
for(i=1;i<=n;i++)
{
printf("\n a[%d]=",i);
scanf("%d",&a[i]);
}
printf("On which position u want to insert element");
scanf("%d",&p);
printf("Insert element:");
scanf("%d",&e);
for(i=n+1;i>p;i--)
{
a[i]=a[i-1];
}
a[p]=e;
n=n+1;
printf("New array list:");
for(i=1;i<=n;i++)
{
printf("\n%d",a[i]);
}
getch();
}
