3. Study the following programs and answer the give DECLARE FUNCTION STRING (S$)
CLS
INPUT "Enter any string=";S
PRINT "Total number of alphabet A ="; STRI
END
FUNCTION STRING (S$)
FOR I = 1 TO LEN (S$)
C$ = UCASE $ (MID (S$, I, 1))
IF C$ = "A" THEN
COUNT = COUNT + 1
END IF
NEXTI
STRING = COUNT
END FUNCTION
(a) For what purpose UCASE is used?
(b) If the input sting is "Education", then what will be output​

[a] create a class called “cycle” which has two instance integer variables as properties, “numberofwheels” and “weight.” create a constructor with two parameters, using the same variable names in the parameter list. assign each variable to numberofwheels” and “weight” respectively. write a separate application to test the class and display its properties. note: do not change the names of the instance variables or the variables listed in the constructor’s parameter list. [b] edit your class cycle by adding a default constructor which will assign the default values of 100 to represent the numberofwheels, and 1000 to represent the weight, by invoking a call to the other constructor. modify your application created in [a] to test the class.

Write a method that takes in an array of point2d objects, and then analyzes the dataset to find points that are close together. be sure to review the point2d api. in your method, if the distance between any pair of points is less than 10, display the distance and the (x,y)s of each point. for example, "the distance between (3,5) and (8,9) is 6.40312." the complete api for the point2d adt may be viewed at ~pf/sedgewick-wayne/algs4/documentation/point2d.html (links to an external site.)links to an external site.. try to write your program directly from the api - do not review the adt's source code.
