A string S is said to be "Super ASCII", if it contains the character frequency equal to their ascii values. String will contain only lower case alphabets (''a''-''z'') and the asci
Modify the FACTOR program in this chapter so that it repeatedly asks for a number and calculates its factorial, until the user enters 0, at which point it terminates. You can enclo

Operation on array: void Array::add( Object& toAdd ) { lastElementIndex++; while( ptrAt( lastElementIndex ) != ZERO && lastElementIndex
Create an applet that bounces a blue ball inside an applet using Thread. The ball (diameter is 10) will start at position (0,0). When the ball hits the edge of the applet, the ba
Illustrate the Function Definition? The C code that explains what a function does is called the function definition. A function definition has the following form Type fun

Explain some String Oriented Library Functions? To make simpler string processing we can use special string oriented library functions. Mainly the C compilers include library f
A: Use operator overloading to present a friend right-shift operator, operator>>. It is similar to the output operator, except the parameter doesn't contain a const: "Fred&" instea
