C++
cpp#include <IOStream>#include "libxl.h"using namespace std;using namespace libxl;3. 创建并打开excel文件在将数组导出到excel之前,我们需要创建一个新的excel文件并打开它。我们可以使用Book类来实现这个目标。
cppint mAIn() { Book* book = xlCreateBook(); if (book) { if (book->load("example.xls")) { cout << "Successfully opened the excel file." << endl;</p> } else { cout << "FAIled to open the excel file." << endl;</p> } } return 0;}在上面的代码中,我们创建了一个Book对象,并尝试加载一个名为"example.xls"的excel文件。如果成功打开文件,则输出"Successfully opened the excel file.",否则输出"FAIled to open the excel file."。4. 添加数据到excel文件一旦我们成功打开了excel文件,就可以向其中添加数据了。我们可以使用Sheet类来实现这个目标。cppint mAIn() { Book* book = xlCreateBook(); if (book) { if (book->load("example.xls")) { cout << "Successfully opened the excel file." << endl;</p> Sheet* sheet = book->addSheet("Sheet1"); if (sheet) { for (int i = 0; i < 10; i++) {</p> sheet->writeNum(i, 0, i + 1); } cout << "Successfully added data to the excel file." << endl;</p> } else { cout << "FAIled to add data to the excel file." << endl;</p> } } else { cout << "FAIled to open the excel file." << endl;</p> } } return 0;}在上面的代码中,我们首先创建了一个名为"Sheet1"的工作表,并在其中的第一列中添加了数字1到10。如果成功添加数据,则输出"Successfully added data to the excel file.",否则输出"FAIled to add data to the excel file."。5. 保存并关闭excel文件完成数据导出后,我们需要保存并关闭excel文件。我们可以使用Book类的save函数来实现这个目标。cppint mAIn() { Book* book = xlCreateBook(); if (book) { if (book->load("example.xls")) { cout << "Successfully opened the excel file." << endl;</p> Sheet* sheet = book->addSheet("Sheet1"); if (sheet) { for (int i = 0; i < 10; i++) {</p> sheet->writeNum(i, 0, i + 1); } cout << "Successfully added data to the excel file." << endl;</p> if (book->save("example.xls")) { cout << "Successfully saved the excel file." << endl;</p> } else { cout << "FAIled to save the excel file." << endl;</p> } } else { cout << "FAIled to add data to the excel file." << endl;</p> } } else { cout << "FAIled to open the excel file." << endl;</p> } book->release(); } return 0;}在上面的代码中,我们在成功添加数据后,调用了book的save函数来保存excel文件。如果成功保存文件,则输出"Successfully saved the excel file.",否则输出"FAIled to save the excel file."。最后,我们通过调用book的release函数来释放内存并关闭excel文件。通过使用libxl库,我们可以很方便地将数组数据导出到excel文件中。在本文中,我们介绍了如何使用C++将数组导出到excel,并给出了一个完整的案例代码。希望这篇文章对你有所帮助!Copyright © 2025 IZhiDa.com All Rights Reserved.
