(=
I'm trying to build a simple menu program that adds data, searches for data, and deletes data depending on what the user wants to do.
I have used Struct here as someone here told me, and also someone else told me to use a vector to make it easier for myself. I did both ways but however, I don't know why it is not working at all! It prints the first person's full name in the file but how can I make it so the code prints all the info as I write the person's full name to the console.

This is an example of how the file looks like.

This is my code for the searching function.

    std::string new_line{""};
};
int search_contact() {
 searching_contact info;
 std::ifstream in_out_file{"out_in_file.txt"};
 if(!in_out_file){
   std::cerr << "File could not be open!" << std::endl;
   return 1;
 }
std::string search{};
std::string lines{};
std::vector<std::string> my_vec;
int line{};

bool found = false;
std::cout << "Enter Key to search: ";
std::getline(std::cin, search);


  //  std::getline(in_out_file , info.full_name);

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 << "\n\tThe fullname is     :    " << info.full_name; 
        //  std::cout << "\n\tThe address  is     :    " << info.address;

         break;
       }
   } 
in_out_file.close();
return 0;
}

CodePudding user response：

Hello here is a working example. The robustness of your program depends on how you check the content of the lines vs the user search pattern. Here I removed all space in search pattern an line for the matching.
