for statement.



15. Write a program in C to multiply 2 matrixes A

and B the resulting matrix in C.

data structures. Write a C program to create and

maintain a singly linked list.



22. Write a C program to calculate the real and

complex roots of a quadratic formula ax2 + bx + c = 0.



23. An n -order polynomial can be evaluated as

follows:



P = (...(aoX + at)X + az)X + ...an)



Write a function to evaluate the polynomial using

an array variable n .



24. Using pointers, write a function that receives a

character string and a character as argument and delete

all occurrences of this character in the string. This

function should return the corrected string with holes.



25. What is meant by Nested structure and Array of

structure? discuss it with example.
