Using C++

A text file has an employee database in the following format. FirstName LastName Salary The salary value has special characters such as $. Write a program to find the average salary of the employees. You HAVE to read all three parameters as strings. Standard C++ does not support converting string to doubles. So, you MUST first convert this string to a C-string. Then, call the function that converts C-strings to floating point numbers. Use HW8Prob1.dat file for your program.

HINT:

1. Use the string library functions to do this problem. Declare three strings variables, read the file one line at a time and assign the read values to correct variables.

2. For the salary parameter, use substr() function to grab the part of string without the $ sign.
