/*Function that runs the program that takes inn 2 arguments. argc(argument count) and argv (argument vector) are how command line arguments are passed to main().
argc is an integer parameter and it is the number of arguments passed to the program.
Program name is always the first argument, so there will be at least one argument to a program and minimum value of argc will be 1.
But if a program has itself 2 arguments the value of argc will be 3.
Parameter argv points to a string array and is called the "argument vector". It is a one dimensional string array of function arguments.*/
