如何重置一个while循环？ [英] How do I reset a while loop?

问题描述

下面是我的工作的一些code的提取物。只是想知道我将如何去重置嵌套循环？它保持在该文件的末尾时，第一环路再次运行。

 而（的fscanf（FP2，％S，wordcheck）！= EOF）//读取从文本文件单词到数组//
    {        对于（i = 0; wordcheck [I];我++）
        {
            wordcheck [I] = tolower的（wordcheck [I]）; //使所有字符小写//
        }        的printf（％S，wordcheck）;        而（的fscanf（FP1，％S，worddict））
        {
            如果（STRCMP（wordcheck，worddict）== 0）//比较字符串//
            {
            的printf（这个词：％s是在字典中的\\ n，wordcheck）;
            dictcount ++;
            打破;
            }            其他
            {
            dictcount ++;
            }            如果（worddict == NULL）
            {
            的printf（你的话：％s不是在字典中的\\ n，wordcheck）;
            }
        }
    }
 

解决方案

使用 fseek的 ：

  fseek的（FP2，0，SEEK_SET）;
 

..或者更简单地说， 退 ：

 退（FP2）;
 

Here is an extract for some code that I am working on. Just wondering how would I go about resetting the nested loop? It remains at the end of the file when the first loop runs again.

while(fscanf(fp2,"%s", wordcheck)!=EOF)//Reads word from text file into array//
    {

        for (i=0; wordcheck[i]; i++)
        {
            wordcheck[i] = tolower(wordcheck[i]);//makes all characters lower case//
        }

        printf("%s", wordcheck);

        while(fscanf(fp1,"%s", worddict))
        {   
            if(strcmp(wordcheck, worddict)==0)//compare strings//
            {
            printf("This word: %s is in the dictionary\n", wordcheck);
            dictcount++;
            break;
            }

            else
            {
            dictcount++;
            }

            if(worddict == NULL)
            {
            printf("Your word: %s is not in the dictionary\n", wordcheck);
            }
        }
    }

解决方案

Use fseek:

fseek(fp2, 0, SEEK_SET);

.. or more simply, rewind:

rewind(fp2);
