Q 1->diff b/t printf(), printf.........
Q 2->can we change the extension file name of header files such as stdio.h to stdio.c
Q 3-> can we open the library.to see its code
1. What?
2. This is pointless and confusing. Files with the suffix of .h are as such for a reason.
Also, in C++, the correct header is "cstdio", not "stdio.h".
3. There are plenty of open-source standard libraries. Most of them are not up to date with C++11.
