} 问题描述:第42行报错。
根据给出的代码,第42行应该是以下代码:
findAllDirs(path);
在代码中并没有定义该函数,因此会报错。需要将该函数名修改为正确的函数名 findALLDirs。修改后的代码如下:
findALLDirs(path); 问题分析:
根据给出的代码,第42行报错 struct _finddate_t未定义。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行和第50行分别定义了fa和handle变量,并在之后使用了_findfirst和_findnext函数来遍历文件和目录。但是与此相关的结构体类型名写错了,应该是struct _finddata_t而不是struct _finddate_t。
将struct _finddate_t修改为struct _finddata_t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 256
long 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; // 修改这里的类型名为 _finddata_t
long handle;
char thePath, target;
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; // 修改这里的类型名为 _finddata_t
long handle;
char thePath;
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 = ".";
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!{:10_254:}{:10_254:}{:10_254:}
根据你提供的代码,第42行报错的原因是函数名称错误。将 findALLDirs 改为 findALLFiles 即可解决此问题。
修改后的代码如下:
#include <io.h>
#include <direct.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX 256
long total;
int countLines(const char *filename);
void findAllCodes(const char *path);
void findALLFiles(const char *path);
int countLines(const char *filename) {
FILE *fp;
int count = 0;
int temp;
if ((fp = fopen(filename, "r")) == NULL) {
fprintf(stderr, "Cannot 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;
char target;
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 findALLFiles(const char *path) {
struct _finddata_t fa;
long handle;
char thePath;
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);
findALLFiles(thePath);
}
} while (_findnext(handle, &fa) == 0);
_findclose(handle);
}
int main() {
char path = ".";
printf("Calculating...\n");
findAllCodes(path);
findALLFiles(path);
printf("You have written a total of %ld lines of code!\n\n", total);
system("pause");
return 0;
}
