code styles by dennismv 2004-12-30 06:44:05
Here are 2 versions of code with identical functionality: 
//first
x();
while (condition())
{
    y();
    x();
}

//second
do
{
    x();
    if (!condition()) 
        break; 
    y();
}
while (1);
x() and y() may be blocks of code.
Which version is preferred ?
