4. What is the output of the following C++ code? int num = 1;
while (num * num <= 50)
{
cout << num << " ";
num = num + 2;
}
cout << endl;

3 5 7 9

Explanation:

First, integer 1 is stored in variable num.

In the while statement, the condition is 1*1 <=50 (Which is true)

If that condition is met, we add 2 to variable num, resulting in 3.

The condition fails at 8 because 8*8 is 64, but the condition is met at 7*7 which is 49 and then we add 2 in variable num, resulting in 9.

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.

explanation:

yes, but you must first make sure that you'll be able to make your turn or you can crash into other vehicles.
