When does a name clash take place in programming
When does a name clash take place in programming?
Expert
A name clash occurs when a name is defined in more than one place. For example: two different class libraries could give two different classes the same name. If you try to use many class libraries at the same time, there is a fair chance that you will be unable to compile or link the program because of name clashes.
