Why do i get this error message?

```
Error: expected a ';'

```

from:

```
int main()
{
    int score;
    double distance;
    char playAgain;
    bool shieldsUp;

    short lives;
    short aliensKilled;

    score = 0
    distance = 1200.76;
    playAgain = 'y';
    shieldsUp = true;
    lives = 3
    aliensKilled = 10;

```

the error is under `distance = 1200.76;` and `aliensKilled = 10;`,
