What is Java Loop

Same statement again and again run use the Loop. Section of code can be repeated with the help of loops.  Repetitive works again and again helps us Loop. Programming there are loop us For Loop, While Loop, Do While Loop. 

Loop: Loop means one kind of Programming Statement. Which executes the same code over and over again. Loop means iteration which work again and again. Loop means how many sequences of Statement.   It continues once it starts until any condition does not reach that is You have to tell when loop is stop.

Write a C program to read the coordinates(x, y) (in Cartesian system) and find the quadrant to which it belongs (Quadrant -I,Quadrant -II, Quadrant -III, Quadrant -IV). Note: A Cartesian coordinate system is a coordinate system that specifies each point uniquely in a plane by a pair of numerical coordinates. These are often numbered from 1st to 4th and denoted by Roman numerals: I (where the signs of the (x,y) coordinates are I(+,+), II (−,+), III (−,−), and IV (+,−).
