Download the HashCode.cpp file and implement the details of the function called hashCode(). The function takes a given string and will need to add the ASCII value for each character in the string to produce a hash key. Assume the hash table has a size of 84 so that a hash code can be generated by taking the value of the sum of the characters modulo 84.

Hint: You only need to provide the details for the areas of the code that are marked with TODO comments. .All of the other areas of code, including the data strings, and function signatures will not change. For the 2 calculateHash() function, a for-loop needs to be created similar to the one in the dumpTable() function, except your for-loop will be user to add the value of each character in the string based on the overall length of the string. You can use the length() or size() string function to determine the length of the passed in string called key. Before the loop, declare an integer variable (e.g. value). Then within the loop, and add the ASCII value of each character to this integer:

// index is the index from the for-loopvalue = value + static_cast(key[index]);

After the loop return the modulus of the value variable (or the name that you have given your integer).

For the insertTable() function, use an if-statement to check whether or not location in the hash table is occupied. This will be similar to the check that is performed in the dumpTable() function, except you will use the hashCode variable instead of the index variable. Print an error message if the position in the hash table is occupied and do not insert the string into the hash table.

Output: The output for the program after the function is implemented should appear as follows:

Chakotay hashCode=64

Janeway hashCode=47

Neelix hashCode=25

Seven of Nine hashCode=8

Tuvok hashCode=33
