Issue #13230 has been updated by Nobuyoshi Nakada.
Probably it equals:
```cpp
unsigned b=0;
do {
cout<<a[b];
if (!(++b<10)) break;
cout<<',';
} while (1);
```
or
```cpp
for (unsigned b=0; cout<<a[b], (++b<10);) {
cout<<',';
}
```
If it were in Ruby:
```ruby
b = 0
while true
STDOUT << a[b]
break unless (b += 1) < 10
STDOUT << ','
end
```
```ruby
b = 0
while (STDOUT << a[b]; (b += 1) < 10)
STDOUT << ','
end
```
```ruby
b = 0
while begin
STDOUT << a[b]
(b += 1) < 10
end
STDOUT << ','
end
```

Do ... while structure improvement
Sometimes the use of jumps such as: continue, break, goto, call to a function, etc. is necessary to avoid the execution of some instructions.
This is the case of the seed, warp and swap loops of this solution for the n queens problem.
To avoid the use of jumps or tricks like for(;;) if(condition)break; on some of these cases, we are suggesting the below improvement to the do ... while loop str
/* author: ncomputers.org */
int main(){
// Allow initializers (extra improvement)
do(bool condition=0){
// Block A
}while(condition){
// Block B
// Variables declared inside the initializer still visible
}
return 0;
}
```
