#include <iostream>
#include <fstream>
int copy_file(const char* SourceFile, const char* TargetFile)
{
// 创建 std::fstream 流对象
std::ifstream in;
std::ofstream out;
try {
// 打开源文件
in.open(SourceFile, std::ios::binary);
// 打开源文件失败
if (in.fail()) {
std::cout << "Error 1: Fail to open the source file." << std::endl;
// 关闭文件对象
in.close();
out.close();
return 0;
}
out.open(TargetFile, std::ios::binary);

} else {
