do-while loops

[bearophile]

One thing that I often find not handy in the design of do-while loops: the scope of their body ends before the "while":


void main() {
    do {
        int x = 5;
    } while (x != 5); // Error: undefined identifier x
}


So I can't define inside them variables that I test in the while().

This keeps the scope clean, but it's not nice looking:


void main() {
    {
        int x;
        do {
            x = 5;
        } while (x != 5);
    }
}
