What is Pretest loop? Can you give example

Question

pretest loop

Answer 1

Pretest loop runs zero(0) or more times.

while (condition)
{
 /* ... */
}

Post test loop runs one(1) or more times but at least once.

do {
 /* ... */
while (condition);

Answer 2

The pretest loop checks the condition and, if true, executes the statements in its body.

For example

i=0;
while (i<3) {
Console.WriteLine(i);
i++;
}

This will output
1
1
1

but next code:

i=4;
while (i<3) {
Console.WriteLine(i);
i++;
}

has no any outputs.
