12. discuss preprocessor directive statements.
PART B
( ans all questions, every ques. carries nine marks)
13. Distinguish algorithm and flowchart. Write an algorithm and draw a flowchart to obtain the number of negative numbers, zeros and positive numbers from a list of n provided numbers.
OR
14. Write short note on the subsequent
i) Structured programming
ii) Top-down programming approach
iii) Bottom-up programming approach
15. discuss in detail the fundamental data kinds in terms of key word, size
in bytes, range of number it can occupy and format specifier etc
OR
16. What is a mixed mode expression?. discuss how it will be evaluated with
an example program illustrating truncation effect.
17.Write a program to sort an array of integers in ascending order and to
print the position of an integer in the sorted sequence.
OR
18. Write a program to manipulate a string in the subsequent way
