Polymorphism means (Points : 2) many forms

Answer:

many forms

Explanation:

Polymorphism is a construct in object oriented programming which means multiple forms.For example: Suppose I have a function which performs the add operation on two integers and another function with the same name which concatenates 2 given strings:

int add ( int a, int b);

string add ( string a , string b)

The two functions represent polymorphic forms of the add function. The function to be invoked at runtime is determined by the runtime argument type.

For example , add (2,3) will invoke int add ( int a, int b);

Similarly, add("hello","world") will invoke string add ( string a , string b);

"Write an iterative function iterPower(base, exp) that calculates the exponential baseexp by simply using successive multiplicat

sp2606 [1]

Answer:

I am writing the function using Python. Let me know if you want the program in some other programming language.

def iterPower(base, exp):

baseexp = 1

while exp > 0:

baseexp = baseexp*base

exp= exp - 1

return baseexp

base = 3

exp = 2

print(iterPower(base, exp))

Explanation:

The function name is iterPower which takes two parameters base and exp. base variable here is the number which is being multiplied and this number is multiplied exponential times which is specified in exp variable.
baseexp is a variable that stores the result and then returns the result of successive multiplication.
while loop body keeps executing until the value of exp is greater than 0. So it will keep doing successive multiplication of the base, exp times until value of exp becomes 0.
The baseexp keeps storing the multiplication of the base and exp keeps decrements by 1 at each iteration until it becomes 0 which will break the loop and the result of successive multiplication stored in baseexp will be displayed in the output.
Here we gave the value of 3 to base and 2 to exp and then print(iterPower(base, exp)) statement calls the iterPower function which calculates the exponential of these given values.
Lets see how each iteration works:

1st iteration

baseexp = 1

exp>0 True because exp=2 which is greater than 0

baseexp = baseexp*base

= 1*3 = 3

So baseexp = 3

exp = exp - 1

= 2 - 1 = 1

exp = 1

2nd iteration

baseexp = 3

exp>0 True because exp=1 which is greater than 0

baseexp = baseexp*base

= 3*3 = 9

So baseexp = 9

exp = exp - 1

= 1-1 = 0

exp = 0

Here the loop will break now when it reaches third iteration because value of exp is 0 and the loop condition evaluates to false now.
return baseexp statement will return the value stored in baseexp which is 9
So the output of the above program is 9.

6. Consider a circle of diameter d cm.

blagie [28]

Circles

Area of Circle is $\pi d^{2} /4$

Total percentage increase in the area of the modified circle is 69%

Explanation:

(a) Given the diameter of the circle be d

Then the radius of the circle = r = d/2

and the area of the circle is given by:

Area(A) = $\pi r^{2}$

A = $\pi (d/2)^{2}$

A = $\pi d^{2} /4$

The area of circle is $\pi d^{2} /4$

(b)

The increase in percentage while changing the dimensions is given by the formula :

Total % increase = a% + b% - (a% * b%)/100

Where ,

a% is the percentage increase in side a

b% is the percentage increase in side b

Let the percentage increase in radius is : a%

Since a% = b%

So the formula is

Total increase % = a% + a% + (a% * a%)/100

Given here the diameter of the circle increases by 30% so a =30

Therefore, putting the value of a in the formula

Total increase % = 30% + 30% + (30% *30%)/100

Total increase % = 60% + 9%

Total increase % =69%

Therefore the total percentage increase in the area of the modified circle is 69%
