### Assignment

Question 1
Write a C Program to calculates the area (floating point number with two decimal places) of a Circle given it’s radius (integer value). The value of Pi is 3.14.

Solution:

``    area = PI * radius * radius;``

Question 2
Write a C program to check if a given Number is zero or Positive or Negative Using if…else statement.

Solution:

``````if(number <= 0.0)
{
if (number == 0.0)
printf("The number is 0.");
else
printf("Negative number.");
}
else
printf("Positive number.");
}``````

Question 3
Write a C program to check whether a given number (integer) is Even or Odd.

Solution:

``````if(number % 2 == 0)
printf("%d is even.", number);
else
printf("%d is odd.", number);
}``````

Question 4
Write a C Program to find the Largest Number (integer) among Three Numbers (integers) using IF and Logical && operator.

Solution:

``````if( n1>=n2 && n1>=n3 )
printf("%d is the largest number.", n1);

if( n2>=n1 && n2>=n3 )
printf("%d is the largest number.", n2);

if( n3>=n1 && n3>=n2 )
printf("%d is the largest number.", n3);
}``````
