What is the <code>auto</code> storage class in C?The <code>auto</code> storage class in C is the default storage class for local variables inside functions. It means the variable is stored in the stack and exists only during the function execution.Click to reveal answer
beginner
Where are
auto variables stored in memory?auto variables are stored in the stack memory. They are created when the function is called and destroyed when the function ends.Click to reveal answer
beginner
What is the lifetime of an
auto variable?The lifetime of an
auto variable is limited to the block or function in which it is declared. It is created when the block starts and destroyed when the block ends.Click to reveal answer
beginner
Does explicitly writing
auto before a local variable change its behavior?No, explicitly writing
auto before a local variable does not change its behavior because local variables are auto by default.Click to reveal answer
beginner
Can
auto variables be initialized at declaration?Yes,
auto variables can be initialized when declared, just like any local variable.Click to reveal answer
What is the default storage class for local variables inside a function in C?
✗ Incorrect
Local variables inside functions are
auto by default, meaning they have automatic storage duration.Where are
auto variables stored during program execution?✗ Incorrect
auto variables are stored in the stack memory, which is used for function calls and local variables.What happens to an
auto variable when the function ends?✗ Incorrect
auto variables are destroyed when the function or block ends, freeing their memory.Does writing
auto explicitly before a local variable change its scope?✗ Incorrect
Explicitly writing
auto does not change the variable's scope; it remains local to the block.Can
auto variables be initialized when declared?✗ Incorrect
auto variables can be initialized at the time of declaration like any local variable.Explain what the
auto storage class means in C and how it affects a variable's lifetime and scope.Think about where local variables live and how long they last.
