For C code: Do not use any function other than getchar, scanf,and printf

Q2.A) Write a programto do the following: Read in two values intovariables X   and y from the keyboard (they may bedecimal values like 2.3). Read in a 3^rd value (which isreally small < 1.0 ) into variable E. Using a loop find out thevalue of N in the below expression. i.e. Each iteration of the loopreduced the value of Y by dividing it by 2. Print out N at the endwhen the condition is met. For most input X and Y values thecondition may not become true and the loop would become an infiniteloop. To break from such \"traps\", you can have a loop count andbreak away. i.e. Count how many iterations it has run through theloop body, and if it goes over some number, say 100, just use\"break\" after saying \"there is no solution for the given numbers\"which should end the program.  

Note: This program conveys the convergence vs divergence innumerical methods.

(a) Let X = 1.02 Y = 8.1, E = 0.05. In each iterationY/2^N values become 8.1, 4.05, 2.025, 1.0125, and stopssince X - 1.0125 is 0.0075 which is < E. This starting Y valueconverges toward a solution.

(b) If X = 1.02 and Y = 9.5, then it would not converge to asolution to meet the criterion, but diverges away.Y/2^N value become 4.75, 2.375, 1.1875, 0.59375,0.2968,goes to 0, but difference goes up.
