First of all, You have to post the question regarding the code
But as per your code, I think you want to sum the a,b, and c variable in which value comes from the command line argument
So you should run the code by the following command in which the parameters are passed at run time
First, OP didn't even use the declared vars. Second, the program won't work unless the values are parsed as int. Third, the output statement to print the sum is in the wrong block.
