Create an Abstract Base class called shape. Derive class rectangle from the base class shape and a class cube from the rectangle class. Data members : Length, width for class rectangle Height for class cube Member function : Area(), print() for class rectangle Volume(), print() for class cube Make function print() as virtual and declare as a pure virtual function in the base class. Write a main program to compute the area of rectangle and volume of cube and display the result using base class pointer.

Design a class polar which describes a point in the plane using polar coordinates radius and angle. Use the overloaded + operator add two objects of polar. (Hint: You need to use the following trigonometric formula: x = rcos(a); y = rsin(a); a = atan(x/y);// are tangent r = sqrt(xx + yy)

void getresult(){}
polar operator + (polar ob);

polar polar :: operator + (polar ob)
{
float x1,x2,y1,y2,x,y,rad,angle;

Check your hard disk for errors

You can help solve some computer problems and improve the performance of your computer by making sure that your hard disk has no errors.
Open Computer by clicking the Start button Picture of the Start button

, and then clicking Computer.
Right-click the hard disk drive that you want to check, and then click Properties.
Click the Tools tab, and then, under Error-checking, click Check Now. Administrator permission required

If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
To automatically repair problems with files and folders that the scan detects, select Automatically fix file system errors. Otherwise, the disk check will simply report problems but not fix them.
To perform a thorough disk check, select Scan for and attempt recovery of bad sectors. This scan attempts to find and repair physical errors on the hard disk itself, and it can take much longer to complete.
To check for both file errors and physical errors, select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors.
Click Start.
Depending upon the size of your hard disk, this may take several minutes. For best results, don't use your computer for any other tasks while it's checking for errors.
