Need help to compile the file in C++ in linux

Hello all,

i am learning C++ on linux.
i have tried to compile very simple code "Fiert.cc"

	Code:
	1: #include <iostream.h> 2: 3: main() 4: { 5: float pi = 3.14; 6: cout << "The value of pi is " << pi << "\n"; 7: return 0; 8: }

when i compiled this code i am getting such warning msg.

Quote:
