Lifetime:

Lifetime of a variable is defined as the time duration during which a variable remains stored in a specific memory location in the machine memory.

Scope:

Static scope:

When the scope of a variable is statically determined it is called static scope. The variables are bound at compile time regardless of when it is executed in the runtime...
