Introduction to the C + + algorithm race Classic Page16 exercise 1-2 temperature

Title: Input Fahrenheit temperature F, output corresponding to C, 3 decimal places reserved.

Tip: C=5 (f-32)/9

(1) Declaring floating-point type variable f,c, respectively, representing the input Fahrenheit temperature and the output Celsius temperature

double F; //  double C; // Celsius temperature of the output

(2) input Fahrenheit temperature F:

scanf ("%lf", &f);

(3) Assign the variable C according to the conversion formula of c=5 (F-32)/9:

C= (double) (5* (f-a)/9);

(4) Output Celsius temperature c:

printf ("%.3lf", c);
