1. (a) Describe the basic structure of C program.
(b) How do variables and symbolic names differ?
(c)Write a C program to calculate the area and circumferences of
a cicle
(d) Describe the basic data types used in C.
2. (a) What is conditional operator? Explain with example.
(b)Describe the IF, IF-ELE, NESTED IF-ELSE with flowchart &
example.
(c) Write a program to compute the sum of the digits of a given
integer number.
3. (a)Write down the general form and flowchart of switch
statement.
(b)Is it good approach to use to go to statement? If not ,
explain why ? write down the use of
break statement.
(c)What is the difference between m--and -- m
(d) Write a C program to compute the roots of a quadratic
equation:
+bx+c=0
[use the following conditions:
(1)There is only one root, if a =0
(x=-c/b)
(2)There are no real roots, if 
-4ac is negative;
-4ac is negative;
(3) Otherwise there are two real roots.]

library & user-defined function? Write down the need of user defined
functions.
(b) What is a pointer? Declare and initialize a pointer
variable.
(c)What do you mean by call by value and call by reference? Give
example.

integers.

function definition.
(b)Describe the different types of string handling functions
with meaning & example.
