Write a function called removeconsonants which removes all the consonants in a given phrase. the upper and lower case of the remaining characters should remain unchanged. the input and output phrases are string scalars. the input string could be any length. hint: the function should work for both upper and lower case. at the start of the function, the input string scalar should be converted to a character vector, the characters should be manipulated, and the resulting character vector should be converted to a string scalar upon exiting. restrictions: loops should not be used. the internal functions and ismember() should be used.

[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.
