在 C++ 中,要限制文件夹不被重命名,可以使用以下代码:
```c++
#include <iostream>
#include <cstdio>
int main() {
char folderName[] = "my_folder";
char newFolderName[] = "new_folder_name";
if (rename(folderName, newFolderName) == 0) {
std::cout << "Folder renamed successfully." << std::endl;
} else {
std::cout << "Folder could not be renamed." << std::endl;
}
return 0;
}
```
在上面的代码中,我们使用 `rename()` 函数将文件夹 `my_folder` 重命名为 `new_folder_name`。如果文件夹成功重命名,则函数返回值为 0,否则为非零值。因此,我们可以根据返回值判断是否重命名成功,并输出相应的信息。如果你想限制文件夹不被重命名,可以在程序中添加条件判断语句,如:
```c++
#include <iostream>
#include <cstdio>
int main() {
char folderName[] = "my_folder";
char newFolderName[] = "new_folder_name";
if (strcmp(folderName, newFolderName) == 0) {
std::cout << "Folder name cannot be same as the new name." << std::endl;
} else if (rename(folderName, newFolderName) == 0) {
std::cout << "Folder renamed successfully." << std::endl;
} else {
std::cout << "Folder could not be renamed." << std::endl;
}
return 0;
}
```
在上面的代码中,我们首先使用 `strcmp()` 函数比较文件夹名称和新名称是否相同,如果相同则打印错误信息,否则调用 `rename()` 函数重命名文件夹。
