我如何从文件中搜索一个人的全名和其他信息

Question

！它会在文件中打印第一个人的全名，但我该如何制作它，以便在我将此人的全名写入控制台时，代码会打印所有信息。

这是我的搜索函数代码。

while (std::getline(in_out_file, lines))
{
my_vec.push_back(lines); 

}

for(int i = 0;i < my_vec.size(); ++i){
if(search == my_vec[i]){
std::cout << search << std::endl;
std::cout << "Match found" << std::endl;
break;
//           std::cout << "ntThe fullname is     :    " << info.full_name; 
//  std::cout << "ntThe address  is     :    " << info.address; 
//  std::cout << "ntThe E-post is       :    " << info.e_post; 
//  std::cout << "ntThe number is       :    " << info.phone_num; 
//  std::cout << "ntThe birthday is     :    " << info.birth_date; 
//  std::cout << "ntAnything else       :    " << info.anything_else; 
} else {
std::cout << "Match not found "<< std::endl;
break;
}
} 
in_out_file.close();
return 0;
}

Hello这里是一个工作示例。程序的健壮性取决于如何检查行的内容与用户搜索模式。在这里，我删除了搜索模式中的所有空格一行进行匹配。
