The difference between a for loop and a do......while

The difference between a for loop and a do......while

In fact, in the functional, there is no difference, because the for loop can implement the Do......while can also be implemented, Do......while can implement for can also be implemented.

But that's what we do when we use the For loop:

for (int i;i>0:i++)

{

Circulation body;

}

And the do......while is like this:

int i=0;

do{

Circulation body;

}

while (I<10)

This is the difference, for the variable of the loop can be defined in the function body, and when the loop ends, the variable disappears and does not occupy memory.

And do......while, the defined variable is global, exists forever, and consumes memory.

Of course, there is nothing on the PC, but if used on the phone, memory is very valuable, can save the province.
