Macro- does not involve in compilation if there is any
logical error also just replaces the code
inline- look like function, but control doesn't goes to
fucntion and execute, it simply replaces the code like
macro but involves in compilation.

Answer / rahul sharma
Macro is a must do thing whearas inline is a hint to the compiler. he may choose not to inline if the function seems complex (it uses recursion or many loops)
Macro can have side effects e.g. the typical
SQUARE(++i); problem
but these problem are not there in inline functions

Answer / vishal
1> Macros are always expanded by pre-processor, whereas compiler may or may not replace the inline definitions. You cant force compiler to make a function inline. It is purely compiler based decision.
2> Debugging macros is also difficult.
3> Expressions passed as arguments to inline functions are evaluated once. In some cases, expressions passed as arguments to macros can be evaluated more than once.

How many types of functions are there in c?
Write a program to maintain student’s record. Record should not be available to any unauthorized user. There are three (3) categories of users. Each user has its own type. It depends upon user’s type that which kind of operations user can perform. Their types and options are mentioned below: 1. Admin (Search Record [by Reg. No or Name], View All Records, Insert New Record, Modify Existing Record) 2. Super Admin (Search Record [by Reg. No or Name], View All Records, Insert New Record, Modify Existing Record, Delete Single Record) 3. Guest (Search Record [by Reg. No or Name], View All Records) When first time program runs, it asks to create accounts. Each user type has only 1 account (which means that there can be maximum 3 accounts). In account creation, following options are required: Login Name: <6-10 alphabets long, should be unique> Password: <6-10 alphabets long, should not display characters when user type> Confirm Password: <must match with the Password, should not display characters when user type> Account Type: <One character long, A or S or G where A for Admin, S for Super Admin, G for Guest> Login Name, Password and Account Type should be stored in a separate file in encrypted form. (Encryption means that actual information should be changed and Decryption means that Encrypted information is changed back to the actual information) If any of the above mentioned requirement(s) does not meet then point out mistake and ask user to specify information again. When Program is launched with already created accounts, it will ask for user name and password to authenticate. On successful authentication, give options according to the user’s type.

stripos — Find position of first occurrence of a case- insensitive string int stripos ( char* haystack, char* needle, int offset ) Returns the numeric position of the first occurrence of needle in the haystack string. Note that the needle may be a string of one or more characters. If needle is not found, stripos() will return -1. The function should not make use of any C library function calls.
