Local and Global Variable Quiz

Where is a local variable declared?

• Inside a function

• Outside a function

• In the definition of function parameters

• In a global scope

When is a local variable created and lost?

• Created at program end and lost at program start

• Created when the function terminates and lost when the function starts execution

• Created when the function starts execution and lost when the function terminates

• Created at program start and lost at program end

Where are global variables stored?

• In a separate memory space

• In a random location in memory

• In a fixed location decided by the compiler

• On the stack

What is the scope of a global variable?

• Inside a function

• Anywhere within the program

• In the definition of function parameters

• In a local scope

What is the advantage of using global variables?

• Limited scope

• Accessible from all functions

• Data sharing is not possible

• Limited memory usage

What is the disadvantage of using local variables?

• Unpredictable results in multi-tasking environments

• Tricky debugging process

• Common data sharing between modules

• Limited scope

When is a global variable created and lost?

• Created when the function terminates and lost when the function starts execution

• Created when the function starts execution and lost when the function terminates

• Created at program start and lost at program end

• Created at program end and lost at program start

What is the disadvantage of using global variables?

• Unpredictable results in multi-tasking environments

• Limited scope

• Data can be modified by any function

• Limited memory usage

What is the advantage of using local variables?

• Unpredictable results in multi-tasking environments

• Guarantee that the values will only be edited by the intended function

• Accessible from all functions

• Data sharing is possible
