*********
10. 10.WAP to perform following actions on an array entered by the user :
i) Print the even-valued elements
ii) Print the odd-valued elements
iii) Calculate and print the sum and average of the elements of array
iv) Print the maximum and minimum element of array
v) Remove the duplicates from the array
vi) Print the array in reverse order
The program should present a menu to the user and ask for one of the options. The menu
should also include options to re-enter array and to quit the program.
11. WAP that prints a table indicating the number of occurrences of each alphabet in the text
entered as command line arguments.
12. Write a program that swaps two numbers using pointers.
13. Write a program in which a function is passed address of two variables and then alter its
contents.
14. Write a program which takes the radius of a circle as input from the user, passes it to
another function that computes the area and the circumference of the circle and displays
the value of area and circumference from the main() function.
15. Write a program to find sum of n elements entered by the user. To write this program,
allocate memory dynamically using malloc() / calloc() functions or new operator.
16. Write a menu driven program to perform following operations on strings:
a) Show address of each character in string
b) Concatenate two strings without using strcat function.
c) Concatenate two strings using strcat function.
d) Compare two strings
e) Calculate length of the string (use pointers)
f) Convert all lowercase characters to uppercase
g) Convert all uppercase characters to lowercase
h) Calculate number of vowels
i) Reverse the string
17. Given two ordered arrays of integers, write a program to merge the two-arrays to get an
ordered array.

20. WAP to calculate GCD of two numbers (i) with recursion (ii) without recursion.
21. Write a menu-driven program to perform following Matrix operations (2-D array
implementation): a) Sum b) Difference c) Product d) Transpose
22. Copy the contents of one text file to another file, after removing all whitespaces.
23. Write a function that reverses the elements of an array in place. The function must accept
only one pointer value and return void.
24. Write a program that will read 10 integers from user and store them in an array.
Implement array using pointers. The program will print the array elements in ascending
and descending order.
25. Add two distances in meter kilometer system using structure.
26. Add two complex numbers using structures.
27. Calculate the difference between two time periods using structures.
These are only examples; more can be included related to the theory.
Use open source C compiler.
