Please help me with this! The main() function for this project is in Arithmetic.cpp; it queries the end user for a string arithmetic expression. The main() function calls the eval() function to evaluate and return the result of the arithmetic expression passed as a parameter. Lastly, the main() function displays the result to the end user. Any number of expressions may be evaluated. The main() function is completed. You are responsible for the implementation of the eval() function.

Example run:
Enter an arithmetic expression on a single line ('q' to end): 5+8
5+8 = 13
Enter an arithmetic expression on a single line ('q' to end) : 2+1-6
2+1-6 = -3
Enter an arithmetic expression on a single line ('q' to end) : 5-4/2
5-4/2 = 3
Enter an arithmetic expression on a single line ('q' to end) : 1+9*2-4
1+9*2-4
15
