Q1. (40)

Input two integers as day and month of a year. Which day of
the year is it? For example, if the day is 5 and the month
is 2, it is the 36th day (5th February). Assume that it is
not a leap year.

Q2. (60)

Write a program that asks the user to input the
co-efficients of a quadratic equation of the form ax^2 + bx
+ c. The input will be the three numbers a, b and c as
double. Find the nature of the roots (real, imaginary,
identical, single, etc.). Output the two roots. Display
imaginary roots as x+iy.

For the above program, you will require to use square roots.
Insert the following line together with the rest of the
program as shown below.

#include <stdio.h>
#include <math.h>
int main()
{
	...
	...
}

Now you can calculate square root as follows:

double x = 1234321;
double result = sqrt(x);

You have to compile your program using gcc -lm
For example, if your file is x.c, you have to run
gcc -lm x.c
and then run a.out
