I am doing Masters in Software Engineering. From College to University i heard from my teachers and instructors that never use GOTO statement in Programming Language.According to
Software Engineering By D. Sundar
USE of goto statements makes a program unstructured and makes it very difficult to understand.
and i also read the same in book by MICROSOFT on its first page that never use GOTO Statmement in Programming.
It always arises question in my mind that if we are instructed that never use GOTO Statement then why it is the part of many common programming languages ?

NOTE − Use of goto statement is highly discouraged in any programming language because it makes difficult to trace the control flow of a program, making the program hard to understand and hard to modify. Any program that uses a goto can be rewritten to avoid them.
"The GOTO statement is generally considered to be a poor programming practice that leads to unwieldy programs. Its use should be avoided."
While overall usage of gotos has been declining, there are still situations in some languages where a goto provides the shortest and most straightforward way to express a program's logic (while it is possible to express the same logic without gotos, the equivalent code will be longer and often more difficult to ...
At least for some programming languages (none of which I'm the designer of, obviously) like C and C++, I imagine it's there because it
The most common example of when goto is often considered good is when doing nested error/resource management in C. See for instance the Linux kernel, a fairly large and successful C project which uses goto for this purpose.
