If the first value printed by the above program is 65517, what will be the rest of output?

Which of the following is TRUE about argv?

Every time we supply new set of values to the program at command prompt, we need to recompile the program.

Even if integer/float arguments are supplied at command prompt they are treated as strings.

The first argument to be supplied at command-line must always be count of total arguments.

In Turbo C/C++ under DOS if we want that any wild card characters in the command-line arguments should be appropriately expanded, are we required to make any special provision?

If the different command line arguments are supplied at different times would the output of the following program change?

#include<stdio.h>

int main(int argc, char **argv)
{
    printf("%d\n", argv[argc]);
    return 0;
}

Does there exist any way to make the command-line arguments available to other functions without passing them as arguments to the function?
