How to use “goto”?

Question

Can anyone tell me how to use “goto”?
By the way, what are the advantages and disadvantages of “goto”?

You can take either C++ or Java for example, for I can only use these two, thank you!

Answer 1

ex.
int i = 5;
goto test;
i = 0;
test:
i++; // i = 6

pro: quick way for jump some line of code, exit from nested loop without particular condition.
con: goto makes difficult to trace the control flow of a program, making the program hard to understand and hard to modify
