感觉code 是对的，就是编译时不显示，，求助。。刚刚学C
#include <stdio.h>

main()
{
      int temp;
      float celsius;
      char repeat;
      do
      {
           printf("Input a temperature:");
           scanf("%d", &temp);
           celsius=(5.0/9.0)*(temp-32);
           printf("The converted F format is %.2f\n", celsius);
           printf("Do you have other data need to be converted?\n");
           printf("Press Y or y if you want to continue");
           repeat=getchar();
           putchar('\n');
           }
      while (repeat=='Y' || repeat=='y');
      
      }

？？？？？？

scanf("%d%*c", &temp);

其实只有两个warning
第一：把celsius改成double类型
第二：在while语句后返回一个值，只要加一条return 0；就行了

%*c
是做什么的？？

LS： 你先告诉我有没有解决问题嘛

scanf和gets不能混合使用，如果一个程序中用scanf的话，一般不能再用gets，反之亦然.

#include <stdio.h>

main()
{
      int temp;
      double celsius;
      do
      {
           putchar('\n');
           printf("Input a temperature:");
           scanf("%d", &temp);
           celsius=(5.0/9)*(temp-32);
           printf("The converted F format is %.2f\n", celsius);
           printf("Do you have other data need to be converted?\n");
           printf("Press Y or y if you want to continue");
           }
      while (getchar()=='Y' || getchar()=='y');

      
      return 0;
}

我试了
没问题

版主的回答确实简洁明了呀！
