Manipulators
There are several classes in the iostream.h header file. One of them is ios class. This class stores the format state. For example, some bits explain the base in which the numbers will be printed, some bits explain the field width. This header file has functions called manipulators, using which the output format can be controlled. There are 3 manipulators dec(), oct(), hex() to set the base in which a given number will be printed. These manipulators are called in two ways :
hex(cout); // Pass the object name
cout<< hex; // use the insertion operator .
But since these manipulators are not member functions of the class , it cannot be used as follows :
cout.hex(); // Not allowed.
pseudo code that will determine if the number is prime or composite
Given an integer n and a permutation of numbers 1, 2 ... , n-1, n write a program to print the permutation that lexicographically precedes the given input permutation. If the given
write a static method with one integer parameter, x that returns the value of the polynomial 3x(2)- 7x + 2
The goto statement This statement can be used to branch to another statement of the program. This is rarely used as it violates the principle of structured programming. Though
