Programming Exercise 1 The genetic information encoded in a strand of deoxyribonucleic acid (DNA) is stored in the purine and pyrimidine bases (adenine, guanine, cytosine, and thymine) that form the strand. Biologists are keenly interested in the bases in a DNA sequence because these bases determine what the sequence does. By convention DNA sequences are represented by using lists containing the letters A G, C, and T or adenine, guanine cytosine, and thymine, respectively). The following function computes one property of a DNA sequence-the number of times each base occurs in the sequence.

config.h:

/**

* List class (Lab 3/Lab 4) configuration file.

* Activate test #N by defining the corresponding LAB3_TESTN to have the value 1.

*

* Because you will copy the List class code to your ordered list directory, having

* two “config.h” files presented the risk of accidentally replacing the one in the

* ordered list directory. So the two configuration files are combined for labs 3 and 4.

*

* NOTE!!! There was an error in the printed book. TEST1 shows up twice in the book.

* The basic List implementation uses TEST1 as described below, then exercise 2

* is activated by TEST2

Expert Answer

 Hello there.

Here, you need to add this to ListArray.h:

// Gets the size.
int getSize() const;

Then add this implementation to ListArray.cpp:

// Gets size.
template <typename DataType>
int List<DataType>::getSize() const
{
cout << this->size << endl;
return this->size;
}

add this to your main function:

// count bases function.
void countBases (
List<char> &dnaSequence, int &aCount, int &cCount,
int &tCount, int &gCount )
{
dnaSequence.gotoBeginning();
cout << “Size of the sequence is: ” << dnaSequence.getSize() << endl;
for (int i = 0; i < dnaSequence.getSize(); ++i)
{
dnaSequence.gotoNext();
switch (dnaSequence.getCursor())
{
case 65:
case 97:
++aCount;
break;
case 67:
case 99:
++cCount;
break;
case 84:
case 116:
++tCount;
break;
case 71:
case 103:
++gCount;
break;
}
}
}

This will not probably work because your methods do not update the size member of the class. I’ll make that work too in an edit.

Cheers,
