Yes.
The only way this can be achieved is by storing the command line arguments in global variables. However, this is not recommended. Global variables should only be used to represent truly global concepts, but command line arguments are local to the main function. The main function's primary role is to parse the command line arguments and invoke the appropriate functions, passing any required arguments (by value) to those functions that specifically require them. The main function's secondary role is to handle any exceptions not handled by the functions that it invokes.
Its way of passing arguments to a function.In this method the value of actual arguments(the arguments in the function call)remains unchanged. changes that we make are effected only to the formal arguments.eg.#include void modify(int,int);// function prototype. this is given to make the compiler aware that there is a function modify. if we didnt do this a error will be shown. otherwise the function body should be written before the function callmain(){int a,b;printf("enter two numbers");scanf("%d %d",&a,&b);modify(a,b);// function call the parameters a and b are actual arguments.printf(" a and b in the main %d and %d",a,b);}void modify(int a,int b)// function header the parameters no1 and no2 are called as formal arguments.{a=a*3;b=b*3;printf(" a and b in function %d and %d",a,b}output:enter two numbers 32a and b in function 9 and 6a and b in the main 3 and 2.this is a program to multiply 3 to the numbers given by the user . here we use function and the arguments are passed by call by value method.here the value of the formal arguments are altered withinthe function but no change happens to the actual arguments . the values in the main does change even after the function call.
Arguments appear in functions and in function calls. Arguments passed to a function are known as actual arguments. The arguments used by the function are known as the formal arguments. In C, all arguments are passed by value, such that the formal argument is a copy of the actual argument.
Its main use is to store local variables, arguments and return address each time a function is called.When your program calls a function the following happen :- The function arguments are put on the stack- The current instruction pointer is put on the stack- The program jumps to the start of the function- Space is allocated on the stack to hold local variables- The function executes- The space holding local variables is de-allocated- The instruction pointer is restored and removed from the stack (we are now leaving the function and resuming the calling procedure)- The arguments are removed from the stack
main function in C programming language and almost in every other main language is the main function that launched after the program starts. It takes two arguments, pointer to the first element of a pointers array (arguments) and number of arguments.If you would write your own functions and link by telling the entry point to your program you would not be able to get arguments any more. There are some code running before actually main function is launched. That code prepares the argument data for main function.But it is possible to change main function to your defined function, but that would require more knowledge of how linker (ld) and for example objcopy utility works.Note: There might be a difference in GNU and Microsoft C/C++ versions.
If you have the function main()... You can use its arguments to pass information.
function name and arguments
When defining your function, do not put any arguments in the definition (e.g. function myFuntion()). Inside the function, you can use func_num_args() and func_get_arg($number) to get the function's arguments.
Commas are used to separate arguments in Excel functions.
Formal arguments are the named arguments defined by the function. Actual arguments are those arguments that were passed to the function by the caller.
Basic structure of a C program is /* Documentation section */ /* Link section */ /* Definition section */ /* Global declaretion section */ /* Function section */ (return type) (function name) (arguments...) void main() { Declaration part Executable part (statements) } /* Sub-program section */ (return type) (function name 1) (arguments...) (return type) (function name 2) (arguments...) . . . (return type) (function name n) (arguments...)

values used with a function are called
It shows you what needs to be put into a function for it to work. You can type the arguments directly into the boxes that are shown for the particular function you are using. It is particularly handy for more complex functions that you are not used to working with.
Optional arguments are ones in a function that you don't have to use. The function will still work without them. It will depend on the function you are using and what you are trying to achieve as to when you use them. Check the help on particular functions that have optional arguments and see what they do. Then experiment with them. They usually give extra information or change how the function works or include extra values. Sometimes you will be able to use them, and other times they are not necessary or a default value is taken.Optional arguments are ones in a function that you don't have to use.

Some functions do and some don't. So it depends on which function you use. Some need more information, like ones that are calculating something like SUM or AVERAGE. Others do not need any arguments like the TODAY function which gives the current date on the computer. So for each function you need to check how to use it and as part of that you will have to find out if it uses arguments and the type and amount of arguments it uses.Some functions do and some don't.
