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);
}
