The central theme of the poem is that the cycle of life from birth to death is inescapable and we should play the roles assigned to us at various stages just like professional actors. Shakespeare compares the world to a stage on which the drama of life is carried out by men at various stages in life, who are actors in the drama. They enter and start acting at birth, the first stage, they finish acting at death, the seventh stage, and exit the stage. In between, they go through the five stages of childhood, youth, working age, maturity and retirement.

Shakespeare considers the world a stage and men and women actors on the stage of life. They play seven roles according to their age. The first stage, as described by the poet, is the infant who is being carried by a nurse. The infant cries and vomits all the time. Later, that infant grows into a schoolboy, not willing to attend school which is the fourth stage of a man‘s life. The third stage is that of a lover who is lost in his thoughts of love. The lover writes poetry in praise of his beloved‘s beauty. In the fourth stage, as he grows older, he joins the army and becomes a soldier. He is physically fit and is aggressive, short-tempered and ambitious in nature. The fifth stage shows that with maturity and wisdom, the family man becomes a judge. He is a fair, healthy man full of wisdom. His look is authoritative and he advises people. The sixth stage is about the man who has grown old and is seen in a pantaloon and spectacles. His authoritative voice has grown weak and his voice trembles as he talks. 

The last stage is about the senile man who loses his teeth, his vision and his hearing. After this, the man‘s part in the play ends and he exits from the stages of his life forever.

Given: A circle touching the side BC of △ABC at P and AB,AC produced at Q and R respectively.

Proof: Lengths of tangents drawn from an external point to a circle are equal.

⇒ AQ = AR, BQ = BP, CP = CR.

Perimeter of △ABC = AB + BC + CA

= AB + (BP + PC) + (AR – CR)

= (AB + BQ) + (PC) + (AQ – PC) since [AQ = AR, BQ = BP, CP = CR]

= AQ + AQ

= 2AQ

⇒ AQ = \(\frac12\)​(Perimeter of △ABC)

∴ AQ is the half of the perimeter of △ABC

Let the breadth of the park is x and the length is 2x + 5.

Area of the park = x \(\times\) (2x + 5) = 250

⇒ 2x² + 5x− 250 = 0

⇒ 2x² + 25x - 20x −250 = 0

⇒ x(2x + 25) -10(2x + 25)=0

⇒ (x - 10) (2x + 25)

⇒ x = 10 or

2x = -25

x = \(\frac{-25}{2} = - 12.5\)

∴ Breadth of the park = 10m 

 Length = 12.5 m

• Princes should choose wise advisors and avoid courtiers.
• Princes must avoid making themselves hated and scorned.

Industrial melanism is an example of the natural selection of a particular form of an organism in an environment which has changed due to the ill effects of pollution created by industrial activities. The peppered moth Biston betularia is found in Manchester, England. It exists in two forms, one a light patchy white and the other a sooty black. 

Under normal conditions, the majority of the white months survive because the trees they rest on have white bark. The black moths have negligible numbers. Due to the industrial revolution in Manchester, the number of industrial establishments increased manifold, and the soot released from their chimneys started coating the tree trunks nearby, turning them black. The black variety now started getting camouflaged better in these blackened trunks, and their number rose and stabilized' The number of the white variety dwindled due to predation as they started getting easily spotted on the black trunks and get easily picked up by predator. This represents a very clear example of the natural selection.

Cyanobacteria are free-living or symbiotic blue-green algae which are capable of converting atmospheric molecular nitrogen into soluble forms like nitrites or nitrates. They enrich the nitrogen content of the soil, thus, acting as a natural fertilizer. They replenish the soil with the nitrogenous compounds and hence are useful in agriculture.

Darwin,s Finches'illustrated adaptive radiation. In this the species, all deriving from a common ancestor, have over time successfully adapted to their environment via natural selection. Previously, the finches occupied the South American mainland but somehow managed to occupy the Galapagos islands, over 600 miles away. They occupied an ecological niche with little competition. As the population began to flourish in these advantageous conditions, intraspecific competition became a.factor, and resources on tire islands were squeezed and could not sustain the population of the finches for long Due to the mechanisms of natural selection, and changes in the gene pool, that  finches became more adapted to the environment. As competition grew, the finches managed to find new ecological niches, that would present less competition and allow them and their genome to be continued. Thus the finches adapted to take advantage of the various food sources available on the island, which were being used by other species. over the long term, the original finch species may have disappeared but by diversifying, would stand a better chance of survival. All in all, the finches had adapted to their environments via natural selection, which in turn, has allowed the species to survive in the longer term, the prime directive of any species.

Conditional operator is also known as ternary operator because it requires three operands and can be used to replace simple if-else code. It is used to check the condition and execute first expression if condition is true else execute other.

Syntax:

Conditional expression? Expression 1 : Expression 2;

Explanation:

If the conditional expression is true then expression 1 executes otherwise expression 2 executes.

Example:

int y=10,x;

x=y>10?1:0;

cout<<x;

Output: 0

#include<iostream.h>

#include<conio.h>

typdef int Num;     //Typedef should be written as typedef

Num full=100;

Num Calc(int X)

{

full=(X>2)?1:2;

return (full%2);   //; is missing

}

void main()

{

int full=1000;

full=Calc(::full);

cout<<::full<<”::”<<full<<endl;

}

#include<iostream.h>

void main( )

{ int A[10] = {3,2,5,4,7,9,10};

int S = 0,p;

for(p = 0; p<=6; p++)

{ if(A[p]%2==0)

S = S+A[p]; }

cout<<S;

}

def chksum():

x= input("Enter a number")

if (x%2 == 0):

for i in range(2*x):

Function Overloading or Functional Polymorphism: 

It is a method of using the same function or method to work using different sets of input. Function overloading is one of the example of polymorphism, where more than one function carring same name behave differently with different set of parameters passed to them. 

Example

int area(int length, int breadth) 

{ 

return(length*breadth);

}

float area(int base, float height) 

{ 

return(base*height/2); 

}

I. M.Tech will never be displayed in the output.

MCA will always be displayed at first in the output.

II. Minimum value of ch=1

Maximum value of ch=3

It is a method of using the same function or method to work using different sets of input. Function overloading is one of the example of polymorphism, where more than one function carrying same name behave differently with different set of parameters passed to them.

Unary operators have only one operand (eg) c++. Binary operators have two operands (eg) +, -, Ternary operators have three operands (eg) ? 

A global variable is a variable that is accessible globally. A local variable is one that is only accessible to the current scope, such as temporary variables used in a single function definition. 

A variable declared outside of the function or in global scope is known as global variable. This means, global variable can be accessed inside or outside of the function where as local variable can be used only inside of the function. We can access by declaring variable as global A
