我的代码
#include <ctype.h>
#include <stdio.h>



int main(void)
{
    int sum = 0;
    char ch;
    int c[26]={1,3,3,2,1,4,2,4,1,8,5,1,3,1,1,3,10,1,1,1,1,4,4,8,4,10};
    printf("Enter a word: ");
    while (1) {
      ch=getchar();
        if (ch=='\n')
          break;
         ch=toupper(ch);
         sum+=c[(int)ch-'A'];
   }
    printf("Scrabble value: %d\n", sum);


    return 0;
}

我在vs下测试没啥问题

应该是编程环境的问题，试了下，我用VS2014可以运行。
