scanf连续输入字符，中间不要忘记\n

 #include <stdio.h>

 int main(void)

 {    

     int precipitating;

     int temperature;

     printf("\nInput precipitating");

     scanf("%d",&precipitating);
     printf("\nInput temperature");
     scanf("\n%d",&temperature);

//When continuous input chars by sacnf ,remember add \n

     if (precipitating)

     {

         if (temperature<)

                 printf("snowing\n");

             else    

                 printf("raining\n");

     }

         else

             {
                 if (temperature<)

                     printf("cold\n");

                 else

                     printf("warm\n");

             }

     return ;
