问题分析:
根据给出的代码,第42行报错。请通过分析代码和错误提示,找出错误的原因并进行修正。
问题解决:
根据代码的逻辑,在第42行调用_findnext函数时,发现函数名使用了中文括号而不是英文括号导致编译报错。
将_findnext(handle,&fa)修改为_findnext(handle, &fa)即可修复此问题。
修复后的代码如下:#include <io.h>#include <direct.h>#include <stdio.h>#include <stdlib.h>#include <string.h>#define MAX 256long total;int countLines(const char *filename);void findAllCodes(const char *path);void findALLDirs(const char *path);int countLines(const char *filename){ FILE *fp; int count = 0; int temp; if ((fp = fopen(filename, "r")) == NULL) { fprintf(stderr, "Can not open the file:%s\n", filename); return 0; } while ((temp = fgetc(fp)) != EOF) { if (temp == '\n') { count++; } } fclose(fp); return count;}void findAllCodes(const char *path){ struct _finddata_t fa; long handle; char thePath[MAX], target[MAX]; strcpy(thePath, path); if ((handle = _findfirst(strcat(thePath, "/*.c"), &fa)) != -1L) { do { sprintf(target, "%s%s", path, fa.name); total += countLines(target); } while (_findnext(handle, &fa) == 0); } _findclose(handle);}void findALLDirs(const char *path){ struct _finddata_t fa; long handle; char thePath[MAX]; strcpy(thePath, path); if ((handle = _findfirst(strcat(thePath, "/*"), &fa)) == -1L) { fprintf(stderr, "The path %s is wrong!\n", path); return; } do { if (!strcmp(fa.name, ".") || !strcmp(fa.name, "..")) continue; if (fa.attrib == _A_SUBDIR) { sprintf(thePath, "%s%s", path, fa.name); findAllCodes(thePath); findALLDirs(thePath); } } while (_findnext(handle, &fa) == 0); _findclose(handle);}int main(){ char path[MAX] = "."; printf("计算中···\n"); findAllCodes(path); findALLDirs(path); printf("目前你总共写了 %ld 行代码!\n\n", total); system("pause"); return 0;}
修复后,错误应该就解决了。如果还有其他问题,请及时提问。
球一个最佳答案谢谢啦!这对我非常重要!
