d) b= ++a – b ++
e) a= d++ - b - -
f) d= --a + c - -
Write C program to convert a total number of days in months and days.

g) relational operator
h) conditional operator
i) logical operator
Write a C program to implement the following operators:
j) Left shift
k) Right shift
l) Bitwise AND
m) Bitwise OR
Week 5th: Programs on Conditional statements
Write a C program to check whether a given number is even or odd using if else conditional statement.
Write a C program to find the biggest of 3 numbers using nested if else statement.
Write a C program to print the colors with respect to its color codes (given 1: RED, 2: GREEN, 3: WHITE and other: YELLOW) using nested if else statement.
Write a C program to find the roots of a quadratic equation ax2+bx+c=0 for all possible combinations of a, b and c. (using else if statement)
(Note: x= -b ±√ (b2-4ac) / 2a)
b2 - 4ac > 0 the roots are real and unequal
b2 - 4ac = 0 the roots are real and equal. i.e x=-b / 2a
b2 - 4ac < 0 the roots are imaginary. i.e x=-b / 2a ± i √ (b2-4ac) / 2a)
Write a C program to print the grades of a student based on the marks obtained: (using switch statement)
Average marks Grade

An electric distributor company charges its domestic consumers as follows:
Consumption in units Rate of Charge
0 to 200 Rs. 0.50 per unit
201 to 400 Rs 100 + Rs 0.65 per unit excess of 200
401 to 600 Rs 230 + Rs 0.80 per unit excess of 400
600 and above Rs 425 + Rs 1.25 per unit excess of 600
Print the amount to be paid by the customer. (Using else if ladder)
