instructions therein. (1 x 10)
2.1 The #undef directive removes a name previously described with #define directive.
2.2 The ‘C’ program can have only 1 command line argument.
2.3 The goto statement causes control to go to a function.
2.4 If you don’t use a return kind in the function declaration, the compiler assumes that the
function does not return anything.
2.5 An array element is accessed using the dot operator.
2.6 continue on statement skips all following statements in the loop body and triggers the next
iteration for the loop.
2.7 The strcmpi function compares 2 strings irrespective of case.
2.8 For loop allows a statement or compound statement to be executed at lowest once.
2.9 The fread function reads formatted data from a stream.

PART TWO
(Answer any 4 questions; Include improper documentation, wherever necessary)
5.
a) Develop a flowchart and then write a C program to display all prime numbers less than
the number entered by the user.
b) discuss the difference ranging from an array, structure and an enumerated data kind.
(10+5)
6. Write an algorithm and then develop a program to evaluate the roots of a quadratic
equation. describe and use a function cal_roots() to compute the roots such that roots are
also available in calling function i.e. use pointers.
(15)
7. Develop a flowchart and then write a C program to obtain the occurrence (single or
multiple) of a substring in a provided string. The substring and string are entered by the
user. Also point out the location at which the substring occurs.
(15)
8.
a) discuss the difference ranging from parameter passing mechanism “Call by value” and “Call
by reference”. Which is more efficient and why?
b) Develop a flowchart and logic to implement the stack data structure using link list.
(5+10)
9.
a) Draw a flowchart and then write a C program to enter the roll number and marks of any
three subjects of few students from the keyboard and write to a file.
b) It is stated that “C is a middle level language and is good for system level programming.”
define 3 facilities available in ‘C’ which support this statement.
