Why use a “do while” loop? [closed]

Answer 1

Its a better way of writing code:

int count = ReadDataFromStream();
while(count != 0)
{
    count = ReadDataFromStream();
}

Can be written using do-while as:

int count = 0;
do
{
    count = ReadDataFromStream();
} while(count != 0);

There are better examples of do-while but I could not recall at this time.
