break cont

[yaraa]

#include <iostream>
using namespace std;
int main ()
{
int i=400;
do
{
i++;
cout<<"before the break\n";
break;
cout<<"after the break,should never print\n";
}
while(i<3);
cout<<"after the do loop\n";
system("pause");
return 0;
}

the output of this code:
before the break
after the do loop

my question is why the sentence "before break" is printed although the while statement is <3 ?

[vlad from moscow]

How is the condition i < 3 connected with the break?! Can you explain?
The break statement means unconditional exit from a loop.

[yaraa]

I mean the while statement is less than 3 and i = 400
how the sentence before break is printed if the while statement is i<3

[Peter87]

Do-while loops always run at least one iteration because the loop condition is tested at the end of the loop.

Actually I don't understand :(
can someone explain me more please

[SamuelAdams]

Don't you know how to test ?

#include <iostream> 
using namespace std;
int main ()
{
int i=400;
do
{
cout << i << endl;    
i++;
cout << i << endl;
cout<<"before the break\n";
break;
cout<<"after the break,should never print\n";
}
while(i<3);
cout << i << endl;
cout<<"after the do loop\n";
system("pause");
return 0;
}

The while() and do-while() loops are described in the tutorial.
