When you declare a program element such as a class, function, or variable, its name can only be "seen" and used in certain parts of your program. The context in which a name is visible is called itsscope. For example, if you declare a variablexwithin a function,xis only visible with...

print(b) // Error occurs: variable b is out of scope}In the preceding program, we can directly observe the effects of block scope by taking a look at the two blocks. The definition of a function opened a new block. We have labeled to this block as B in our example. Within A, the...
