  Your task is to make a class that represent a DNA strand. A DNAStrand will track its length and a character array to store the bases (which will be stored as A, C, G, or T). We will normally create a DNAStrand by doing something like: DNAStrand strand1("ACTGAGATA"); DNAStrand will also provide various operators and functions for doing things like combining two strands, getting the complement of a strand or searching for one strand inside another. DNAStrand substr(int start, int length) const - Get a new DNAStrand that contains the indicated portion of this DNAStrand. You will probably need/want the DNAString(int length) constructor as a helper for this. This should throw an out_of_range exception if the index or length are negative, or if the start + length would go past the end of the strand. Remember: you may NOT use std::string in this project. You can use functions from the cstring library.  Your task is to make a class that represent a DNA strand.
