here are some difference between c and c++ ---
1. C is a PROCEDURE oriented programming language.
-> C++ is a OBJECT oriented programming language.
2. We can do programming through STRUCTURE,but NOT with the
help of the CLASS.
-> We can do programming through CLASS in c++.
3. C is a LOW level language.
->C++ is a HIGH level language.
4. C is a TOP->BOTTOM programming approch.
->C++ is a BOTTOM->TOP programming approch.
5. C is a collection of FUNCTIONS.
-> C++ is a collection of FUNCTIONS and/or CLASS.
6. c language main focuses on PROCEDURES.
-> c++ programming main focuses on OBJECTS.
7. In C,DATA can be MOVE openly around in the system from
function to function.
-> In C++,DATA is HIDDEn.It can not be accessed by external
functions.
8.C can not support all the feature of the C++.while c++
support all the features of C.
9. C NEEDS FORMAT CHARACTERS for printing & scanning.
-> C++ DOES NOT REQUIRED FORMAT SPECIFIER for printing and
scanning variable.
10. C variables are DECLARED in declaration section.
-> C++ variables are DECLARED any where in the program.
11. In C,we use PRINTF() ,SCANF() as standard input/output
functions.
-> In C++,we can use COUT<< or CIN>> as standard
input/output function.
12. In C,you can NOT OVERLOAD a function.
-> In C++ ,you can OVERLOAD the operator as well as
functions.
13. C does NOT have NAMESPACE for avoid name collisions.
-> c++ has NAMESPACE feature.
14.C does NOT have REFERENCE variables.
-> In C++ ,REFERENCE variables are USED in functions.
15. In C,constants are defined as 'MACROS'.
-> We can make a use of 'CONST' TO declare a constant.
16.In C program , the MAIN() should NOT RETURN a value.
-> In C++,MAIN() should RETURN a value.
17. C does NOT SUPPORT DEFAULT arguments.
-> C++ PROVIDES DEFAULT argument concept.

write a code for this. serial_number contained in the header of the file will be read , if this serial number is less than a previous serial number within a successfully processed file, or is the same as another serial number within a successfully processed file, or if the field contains anything other than 7 digits, then the file must error with the reason ‘Invalid SERIAL_NUMBER’.
