What can be written to perform a certain number of iterations or to iterate until a specific result is achieved? A. an ordered data structure
B. a for loop
C. a print function
D. an array

The answer to this question is given below in the explanation section. However, the correct option is B. i.e a for loop.

Explanation:

The correct answer to this question is for-loop. Beause, in the for loop is written to perform a certain number of iterations or to iterate until a specific result is achieved.

for example, to calculate the average of 10 numbers, we use the for loop to iterate statements written in its body 10 times to calculate the average.

when the specific numbers of the iteration are reached it will get terminated.

for example

for (int i=0; i<=10; i++)

{

// perfrom average, code

}

this loop iterate 10 times or less, when it reached above the limit it gets stopped.

however, the other options are not correct, because an ordered data structure is like a list of order data, print function print something to the user or on screen. while an array is like a list of data of the same data type.

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.
