Q1. (50)

Write a program to input two positive integers a and b and
find the smallest multiple of the second integer greater
than or equal to the first. Assume that the second number
will be less than the first. For example, if the input
numbers are 41 and 3, the output should be 42.

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

Q2. (50)

Write a program to input a point (x,y) and identify the
quadrant in which it lies. Assume top-right quadrant as 1st
and anti-clockwise ordering. Input another point (a,b) and
find the distance between the two points.
