Use C++
A DNA sequence is a string that contains only the characters
‘A’, ‘T’, ‘C’, ‘G’ (representing the four bases adenine, A;
thymine, T; cytosine, C; guanine, G). You are to implement a C++
class that can count the number of times a specific triplet of
bases (also called a codon, e.g., “ATC”, “GGG”,
“TAG”) appears in a set of DNA sequences.
For example, given two DNA sequences: TCTCCCTGACCC
and CCCTGACCC
Implement your logic in a class Codons. The class should
have 3 public member functions:
These public member functions will be called from the provided
main program (dna.cpp) and the answers checked there. You can
modify the main function to test your code with different input
cases to make sure the logic will work in the general case - we
will test your code with different DNA sequences not included
here.
Hint:
Data structures: you are
encouraged to use the C++ Standard Library containers.
