complete the code in prob19.cpp that will cause this program to display the first and last name, with last name displayed first followed by a comma and a space followed by first name. The name should be followed on the same line by three test scores and the average of these three scores. All three tests should be random numbers between 0.0 and 100.0.. The average should be computed by adding the three scores together and dividing the total by three. Use variables to hold all values. The variable for the firstname should get its value from a random first name in the list of first names (fname) provided, and the variable for the lastname should get its value from a random last name in the list of last names (lname). Use a fourth variable to hold the concatenation of the lastname followed by a comma and space followed by the first name. Display the name, test scores and average grade so they line up under the headings that are provided in the code.. Use the variables in the output statement. Be sure to update the comments to note your name as the author and the date you completed the code. Submit your final, error-free source file (the .cpp file).
