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.
