In both Do-until and Do-While,Code will be executed atleast once.
But,the difference is Do-until executes the code until the specified condition is reached.Once the condition is reached it stops executing the code inside the loop.

Do-While will execute the code till the specified condition is true. once the condition becomes false,it exits from loop.

Answer / viji

Do until will execute once when the condition is false whereas do while will execute only when condition is true

Answer / sarabjit

In do until , the code is run atleast once
eg: do
{
/// statement
} until i=0

whereas in while it checks whether condition is false/true , and then it executes the statement
while i=0 ******if i=0 is true*****
{
execute the statement
}
