Explanation of Solution
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:
A scope is defined as the context within the file of a computer program, in which variable names and identifiers are valid and can be used, or within which a declaration shows some effect.
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...
