Q1.Evaluate the following expressions with 3 and 7 as operands 7 / 3 3 / 7 7 % 3 3 % 7

Q2.Given the constant and variable declarations

#define E 2.78

#define MAX 100 double x, y;

int a, b, i;

indicate which of the following statements are valid and where valid, give the value stored into the target variable. Assume that a is 4, b is 3, and y is -2.0.

(a )	i = a % b;	(b)	i = (MAX 90) / a;
(c )	i = a % b * b;	(d)	x = a / y;
(e)	x = E * y;	(f)	i = a * E;
(g)	x = E / y;	(h)	x = b / a;
(i)	x = a % (a / b);	(j)	x = b % (b / a);
(k)	x = (double) a / b;	(l)	x = (double) (a / b);

Q3.

Redo the above question with new values of 3 for a, 7 for b, and 3.0 for y.

Q4.The printf function prints a value of 1025 using a decimal format. What is the output produced (use an underscore character to indicate a space) for the following formats.

%1d %4d %5d %6d

Now repeat this exercise for the value -1025 (negative of the above value).

%1d %4d %5d %6d

Q5.For the floating point values of 108.435, -0.033, -37.886, 4.56, and -998.5, what is the output produced by printf (u/scores for spaces again) with the format %6.2f.

Q6.If you wish to read in 3 values (one double, and 2 integers) from the keyboard, what format string would you pass to the scanf library function.

Q7.Trace the execution of the following expressions using an evaluation tree. Use the values as follows: i = 5, j = 7, k = 4, m = 6, n = 8, flag1 = 0, flag2 = 1 (all integers), and a = 3.5, b = 8.0, c = 0.0, d = 40.0 (doubles).

n (i + j / 2) + k * m

3 * (a b) / (2 * (c d))

!flag1 && flag2 && (a <= b) && (k*m < 20)

Q9.Write a function in C that will take in Cartesian coordinates (x, y) as two doubles and will return an integer which is the quadrant number of that particular point. Assume that the x and y axes themselves are on the positive side of each half-plane.

Q10.Write a function that will accept two integers as input and will return the sum of all the integers from the first value, up to and including the second value. Assume the integers are always passed to the function with the lower value first and the higher value second. How would you cater for the inputs being out of order?
