In the bucle do... While, the sentences written into the "do... While", at least it's executed one time, in the while if the condition is false it's executed never.

while: 0 or more times
do-while: at least 1 time or more

you use a do-while when you need definitely need to execute your code once but arent sure if u need it multiple times.
