Answer:
1.
printf("%lf", outsidetemperature);
2.
printf("%.2lf\n", outsidetemperature);
Explanation:
1.
The command to print is printf.
It has an argument, that is the datatype. When it is double, it is %lf.
So:
printf("%lf", outsidetemperature);
2.
Again printf. If you want m digits in the fraction, you use %.mlf. So for 2 digits is %.2lf. For a new line, you put a \n after the datatype argument. So:
printf("%.2lf\n", outsidetemperature);
