Actually speaking - Nothing. The Java program will start running. The args is just an optional parameter and you can pass it if you want and ignore it if you dont want to pass any runtime arguments
In JCL it would be of the form exec pgm=mypgroam, parms="/B" where the info after the "/" is the parameter strring.
It is better to do this when the function needs to work on the entire array, rather than on individual elements. However, do not pass the array by value; always pass by reference.
An array is still an array, regardless of how you pass it into functions. It is still an array-type variable at the beginning of a function. However, the function itself may manipulate the array by "imploding" it into a string with a delimiter, using array values with only specific keys, and such.
Passing array elements to a function is achieved by passing the individual elements by reference or by value, just as you would any other variable. However, passing the entire array requires that you pass a pointer-to-pointer to the array along with the dimension(s) of the array.

But of course.
Put their names into the parameter-list.
If you have the function main()... You can use its arguments to pass information.

argv, which is the second parameter of function mainint main (int argc, char *argv[])

parameter
the simple and efficient way to pass an array is pointer to an array like that int (*p)[30] ; // pointer to an array of integer having 30 element

Yes. Since passing arrays is a special use of call by reference, simply pass the address of the sub array instead of the primary array. int a[10] = { ... }; myfunction (a); // pass the first element's address myfunction (&(a[3]); // pass the fourth element's address
