Question

我在do ... while循环中工作。我需要修改一些代码。

我所拥有的计划是：

    #include <stdio.h>
    #include <conio.h>
    void main()

     {

       int n, score, ctr=1, total=0, ts=0;
       float average=0;

       printf("\n\nEnter How Many Scores: ");
       scanf("%d",&n);

       do{

            printf("\nEnter score %d: ",ctr++);
            scanf("%d",&score);
            total+=score;
            average=total/n;
            if(score>=50&&100<=score);
              printf("\nTotal Score from 50-100: %d",score);
            if(score%2==0);
              printf("\nTotal even number score: %d",score);
            if(score%2!=0);
              printf("\nTotal odd number score: %d",score);

       }while(ctr<=n);
         printf("\nTotal Score: %d",total);
         printf("\nAverage: %.2f",average);

       getch();

    }

我需要找到的总分是50-100，总偶数得分和总奇数得分。提前谢谢。

Answer 1

你有if(score>=50&&100<=score);

如果您希望得分在50到100之间，则需要将其更改为if(score>=50 && score<=100)。

你也需要在if语句之后删除分号。

此外，如果要计算偶数和奇数分数的总数，则需要跟踪每个分数的单独变量。像这样：

#include <stdio.h>
#include <conio.h>
int main(void)
{
    int n, score, ctr=1, total=0, ts=0;
    float average=0;
    int odds=0;
    int evens=0;

    printf("\n\nEnter How Many Scores: ");
    scanf("%d",&n);

    do{
        printf("\nEnter score %d: ",ctr++);
        scanf("%d",&score);
        total+=score;

        if(score>=50 && score<=100 )
        printf("\nTotal Score from 50-100: %d",score);
        if(score%2==0)
        {
            evens++;
            printf("\nTotal even score: %d",evens);
        }
        if(score%2!=0)
        {
            odds++;
             printf("\nTotal odd score: %d",odds);
        }
    }while(ctr<=n);

    printf("\nTotal Score: %d",total);


    if((odds+evens) !=0) average= (float) total/(odds+evens);
          printf("\nAverage: %.2f", average );
    getch();
}

如果你可以使用单独的变量来获得总分，总分数和总分数，那就更好了。然后在条件检查中更新相应的总变量。

int total_fh = 0, total_es = 0, total_os = 0;

if (score >=50 && score <= 100) 
{
    total_fh += score;

    if (score % 2 == 0) {
        total_es += score;
    }
    else if (score % 2 != 0) 
    {
        total_os += score;
    }
 }

然后在循环外部，使用printf语句打印分数。
