Memory Allocation in C Programming Language Quiz

What is the major benefit of dynamic memory allocation in C programming?

• Enables easy printing of data

• Provides complete control of your life

• Allows us to create dynamic arrays

• Automatically optimizes code

What does the malloc function do in C programming?

• Optimizes memory usage

• Reserve memory and return a pointer to that location

• Prints the content of memory

• Deletes memory allocation

Why is using a void pointer with malloc generally frowned upon?

• Lacks type safety

• Limits memory allocation size

• Causes memory leaks

• Slows down program execution

How can you calculate the size of memory to reserve using malloc for storing 10 integers?

• Size of an integer minus 10

• Size of an integer plus 10

• Size of an integer divided by 10

• Size of an integer multiplied by 10

What should you do after dynamically allocating memory in C to ensure proper memory management?

• Print the memory content

• Reallocate the memory with a larger size

• Leave the memory as is

• Free the allocated memory using the free function

In C programming, how can you check if a memory allocation using malloc was successful?

• Check if the pointer returned by malloc is not null

• Check if the pointer returned by malloc is null

• Use a try-catch block

• Restart the program

What is the purpose of reallocating memory in C programming?

• To increase or decrease the size of allocated memory

• To free up memory space

• To print the memory content

• To optimize program execution

Why is it recommended to use malloc for returning data defined locally in a function in C programming?

• Prevents returning stack memory that will be invalid outside the function scope

• Speeds up program execution

• Enables parallel processing

• Reduces memory usage

What is a common practice when working with dynamically allocated arrays in C programming?

• Keeping track of both the size and count of the array

• Using void pointers for all allocations

• Printing the entire memory content

• Avoiding reallocation of memory

What warning might you receive if you try to return locally defined stack memory in C programming?

• Address of Stack memory associated with local variable array returned

• Stack overflow error

• Memory allocation failed

• Invalid return statement
