Answer:

printf("%lf", outsidetemperature);

printf("%.2lf\n", outsidetemperature);

Explanation:

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);

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);

myarr[i][x] = (i+1);

myarr[i][x] = myarr[i-1][x] + myarr[i][x-1];

Panes created using the vertical split bar scroll together horizontally. true or false.

Nataly_w [17]
