Help me optimise my code!

In other words, you can do this:

Code:

---

int function() {
    int x = 2 * 2;
    return x;
}

int main() {
    int x = function();
    return 0;
}

---

Of course, you don't have to use the same variable name in main().

Yes, but you have to make a local block.
Example:

Code:

---

switch(x)
{
    case y:
    {
        float z = 0.123f;
        // ...
    }
}
