Answer 1

This reads your numbers. It uses the first integer to read that many scores. It doesn't keep those scores at the moment only the last one. You would need an array to store them, if need them all at once. You could add them up and output an average easy without storing them.
int n, g;
scanf("%d", &n);
for (int i = 0; i < n; i++)
scanf("%d", &g);
