#include <stdio.h>int main(void)
{
int choice = 0;
double temperature = 0.0;
printf("This program can do the following:\n"
"1. Convert from degrees Centigrade to degrees Fahrenheit\n"
"2. Convert from degrees Fahrenheit to degrees Centigrade\n"
"Select the conversion (1 or 2): ");
scanf("%d", &choice);
printf("Enter a temperature in degrees %s: ",//这句是不是多余的//
(choice == 1 ? "Centigrade" : "Fahrenheit"));//为什么要用这个表达式，难道不和下面的if重复吗//
scanf("%lf", &temperature);
if(choice == 1)
printf("That is equivalent to %.2lf degrees Fahrenheit\n", temperature*9.0/5.0+32.0);
else
printf("That is equivalent to %.2lf degrees Centigrade\n", (temperature-32.0)*5.0/9.0);
return 0;
}
