Q1. Write a C program that prompts the user to enter the value of an angle in degrees.which a line makes with the positive x-axis.

Then the program must print which quadrant the line lies in. Also, if the angle is 0, 90, 180 or 270 degrees - the program must print the line lies on positive x axis for 0 degree, negative y axis for 270 degrees etc.

Q2. Write a C program that calculates and returns the real roots of a quadratic equation. If there are no real roots - the program need not calculate - but must flag/print that there are no real roots. You must submit sample run for both cases - real and imaginary roots.
