Run the example with command line argument

Java:  

        javac readText.java

        java readText test1.txt
C++:  

        complie readText.cpp and generate readText.exe
        readText test1.txt

The output is like:

        current Line 200
        current Line 50
        current Line 20
        current Line 30
        current Line 40
        current Line -2
        current Line -2
        current Line 10
        current Line -999
        sum = -653

Comments: test1.txt is the first test file given to you. Running the example will output every integer in the file and their sum. You can use your own test files by replacing test1.txt with your own file name. Your test files must be well-formatted, that is, exactly one integer each line.
