Answer 2

When you need to do one particular thing: you want to always execute a block, and then 'maybe' repeat it.

int i=0;
do{
//do something
i++;
}while( i<10 );

The block of code is always executed at least once, regardless of the condition check at the bottom.

Then, until i is less than 10, we'll repeat the block.

Answer 3

while loop check condition before execution of the loop& the do-while loop verifies the condition after the execution of the statements inside the loop.

Answer 4

do {} while executes the code in its body at first and then checks the condition. while {}, on contrary, checks the condition and only then, depending on the result of its evaluation, moves on or not to its block. That means that do {} while will execute its code at least once, whereas simple while {} may not execute any code at all.

Answer 5

There's a chapter covering the difference between the two.
