Does there exist any way to make the command line argument available to other function without passing them as arrguments to function?
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.

What does char argv mean?
The full form of this is: char* argv[]; Where argv is a pointer to a null-terminated array of null-terminated strings. We use this type of argument to pass command line switches to the main function: int main (char * argv[], int argc); The names of these arguments, argv and argc, are conventional. The argc argument tells us how many elements are in the argv argument, such that argv[0] is the full-qualified name of the executable and argv[argc] is the null-terminator of the array. Any and all other elements (argv[n], such that 0<n<argc) represent programmer-defined command-line switches.
