Question

For the following C code, indicate the memory region where each variable/data structure is stored:

a. num

b. i

c.data_storage

d. desired_data

e. The code itself

int num = 50;

void store_data(int a)

{

int i = 0;

int *data_storage = malloc(1000*sizeof(int));

int desired_data[10];

while(i < num)

{

data_storage[i] = a;

if(i < 10)

{

desired_data[i] = a;

}

i++;

}

}

Answer 1

The variables in the given C code are stored in different memory regions: num and i in stack memory, data_storage in heap memory, desired_data in stack memory, and the code itself in the code segment memory region.

Step-by-step explanation:

In the given C code, the variables are stored in different memory regions:

• num: This variable is stored in the stack memory. It is a global variable and can be accessed throughout the program.
• i: This variable is also stored in the stack memory. It is a local variable and its memory is allocated when the function store_data is called.
• data_storage: This is a dynamic memory allocation and is stored in the heap memory. It is allocated using the malloc function.
• desired_data: This array is stored in the stack memory. It is a local variable and its memory is allocated when the function store_data is called.
• The code itself: The code is stored in the code segment memory region.
