How operator overloading differ from function overloading?
Function overloading is multiple definition with different signatures(the parameters should be different) for the same function. The parameter list have to be different in each definition. The compiler will not accept if the return type alone is changed. Operator overloading is defining a function for a particular operator. The operator loading function can not be overloaded through function overloading.
Why a friend function cannot be used to overload the assignment operator?
Assignment(=) operator is a special operator that will be provided by the constructor to the class when programmer has not provided(overloaded) as member of the class.(like copy constructor). When programmer is overloading = operator using friend function, two = operations will exists: 1) compiler is providing = operator 2) programmer is providing(overloading) = operator by friend function. Then simply ambiguity will be created and compiler will gives error. Its compilation error.
Why use awk -v command?
This is used when you want to give a variable in an awk script a value before the script starts executing, even before the BEGIN block. You would do this on the command line if the variable needs different values for different executions rather than hardcoding it in the awk script itself.

How do you write a awk script program in unix?
That is a difficult question to answer - the question is rather vague on what you intend to do. An awk script is a file containing awk commands that operate on 1 or more data files, based on selectors and actions resulting from that selector. It all depends on what you want to do with the data. The program itself is just a text file that can be created by any editor and then interpreted with the awk command.
Why awk -f command is used?
The awk programming/scripting language is used to pattern match text and then do something with the result. Using the -f option indicates that the awk program/script has been stored in an external file instead of being specified inline with the command.

What are Nawk scripts?
Nawk is an Awk replacement on *nix operating systems. It is very good at sorting data in columns and search functions. A classic awk command would be: "$awk '/Home/ {print $3}' file > home.txt" this consists of calling the awk interpretor to open the file "file", telling it to search for the word "Home" and when it finds that, print the 3rd column from that line out to a file named home.txt. Awk automatically uses tab (\t) as the field separator ($FS) and you can change this if the input file uses something else besides the tab, e.g. : or ; or & and so on. there are a lot of awk tutorials on the web and most are pretty good.
