c - C 编程新手 : Math Quiz grade printout

Question

数学测验询问您想要解决多少个问题，并显示加法和减法的随机数，然后对您对问题的回答进行评分。我遇到的问题是正确打印它。我需要显示我做对了多少个以及我总共尝试了多少个。示例 5 分中的 4 分正确(成绩:2/5 正确)，但我正在恢复此示例“成绩:2/-1832609951”任何人都可以帮忙，谢谢!

包括

    int main()
    {
     int NumberOfTimes,AddAns,SubAns,AddCorrect=0,SubCorrect=0,CorrectAnsAdd,CorrectAnsSub,TotalCorrect,TotalWrong,Add$
     int i,a,b,c,d,e,f,g;

     printf("\n");
     printf("-------------------MATH QUIZ------------------------\n");
     printf("Enter the number of Math problems you want to solve:");
     scanf("%d", &NumberOfTimes);
     printf("\n");
     srand(time(NULL));
     for (i=0;i<NumberOfTimes;++i)
     {

      b = rand() %3 + 1;
      c = rand() %3 + 1;

      a = rand() %2 + 1;


      if (a == 1)
        {
        printf("%d + %d = ", b,c);
        scanf("%d", &AddAns);
        d = b + c;
        if (AddAns == d)
           {
            printf("  +Correct\n");
            AddCorrect = AddCorrect + 1;
           }
        else
           {
            printf("  +Wrong, it was %d\n", d);
            AddIncorrect = AddIncorrect + 1;
           }
        }
      if (a == 2)
       {
        printf("%d - %d = ", b,c);
        scanf("%d", &SubAns);
        g = b - c;
        if (SubAns == g)
           {
            printf("  +Correct\n");
            SubCorrect = SubCorrect + 1;
           }
        else
           {
            printf("  +Wrong, it was %d\n", g);
            SubIncorrect = SubIncorrect + 1;
           }

       }

      }
      TotalCorrect = AddCorrect + SubCorrect;
      TotalWrong =  AddIncorrect + SubIncorrect;
      printf("\n");
      printf("Grade: %d/%d\n",TotalCorrect,TotalWrong);
      printf("\n");
      return 0;
}

Answer 1

我再次查看了问题，找到了我应该针对“错误数量/总数”执行此操作的解决方案

TotalCorrect = AddCorrect + SubCorrect;
  printf("\n");
  printf("Grade: %d/%d\n",TotalCorrect,NumberOfTimes);
  printf("\n");
  return 0;
