html - For 循环正在添加一个选项卡本身

Question

我正在编写一个程序来快速编写我的 .html 文件。这些 .html 文件主要包含问题和答案。选项为MCQ(多项选择题)形式。第一个问题与这个程序配合得很好，但是当我输入第二个问题时，它向右移动了一个选项卡和选项。我不明白为什么。代码在这里:

int main(){    
    int track=0;
    int thread=0;
    int question_no;
    char options[4][50];
    FILE *fp = fopen ("test.html", "w");
    printf("\n\aHow many questions?");
    scanf("%d",&question_no);
    while((c = getchar()) != '\n' && c != EOF) ;
    char question[question_no][100];

    for(track=1;track<=question_no;track++)
    {
        fprintf(fp,"\n<div class=\"question\"> ");
        printf("\n\aQuestion number %d.",track);
        fgets(question[track-1],sizeof(question[track-1]),stdin);
        fprintf(fp,"\nQ%d. %s </div>",track,question[track-1]);
        fprintf(fp,"\n<div class=\"options\">");
        fprintf(fp,"\n<form>");
        for(thread=1;thread<=4;thread++)
        {
            fprintf(fp,"<label><input type=\"radio\"id=\"q%dop%d\" name=\"q%d\" value=\"q%do%d\">",track,thread,track,track,thread);
            printf("\n\aOption. %d:",thread);
            fgets(options[thread-1],sizeof(options),stdin);
            fprintf(fp,"\n%d. %s",thread,options[thread-1]);
            fprintf(fp,"</label><br/>");
        }
        fprintf(fp,"\n</form>");
    }
    fclose(fp);
}

您缺少结尾 </div> .

for(track=1;track<=question_no;track++)
{
    fprintf(fp,"\n<div class=\"question\"> ");
    printf("\n\aQuestion number %d.",track);
    fgets(question[track-1],sizeof(question[track-1]),stdin);
    fprintf(fp,"\nQ%d. %s </div>",track,question[track-1]);
    fprintf(fp,"\n<div class=\"options\">");    // This div is never closed!
    fprintf(fp,"\n<form>");
        for(thread=1;thread<=4;thread++)
            {
                fprintf(fp,"<label><input type=\"radio\"id=\"q%dop%d\" name=\"q%d\" value=\"q%do%d\">",track,thread,track,track,thread);
                printf("\n\aOption. %d:",thread);
                fgets(options[thread-1],sizeof(options),stdin);
                fprintf(fp,"\n%d. %s",thread,options[thread-1]);
                fprintf(fp,"</label><br/>");
            }
    fprintf(fp,"\n</form>");
    fprintf(fp,"\n</div>");    // Add this row to close the div
}
}
