What is a local variable?

Rating:

A local variable is defined inside a block or a method. The lifetime of such a variable is limited by the lifetime of the block in which it is enclosed. It is necessary to initialize a local variable; otherwise, a compile time error will occur. If the same name is used for an instance variable as well as for a local variable, the variable with the local scope will get priority inside the block.
