fstream: Saving parts of a line into different strings without the white spaces included ?

[PolloLoco4645]

Lets say I have a text file with a bunch of names on it.

The position where each element start remains constant throughout the lines(example, last name starts after 25 spaces).
I want to save each name into a respective string. like this

#include <iostream>
#include  <fstream>
using namespace std;

int main()
{
ifstream inFile;
string aLine;
string firstName, middleName, lastName, maidenName; 

inFile.open("some file");
	if (inFile.fail())
	{
		cerr << "Error" << endl;
	}
	getline(inFile, aLine);

firstName = aLine.substr(1 - 1, 25);
middleName = aLine.substr(26 - 1, 25);
lastName = aLine.substr(51 - 1, 50)
maidenName = aLine.substr(101 - 1, 50);

return 0; 
}

How do I do this without copying the white spaces into the strings ? Again it's a file with a bunch of names on it.

it'd be helpful to share at least a couple of lines from the text file as well

Here. Ignore the numbers at the end for now.

You don't need to substring the line into first, last etc names in this case but by defining a Person struct you can read off the data directly into the data-members of the object and save them in a std::vector<Person>. This, of course, assumes that the file is uniform in that each person has all the attributes, no missing data or other irregularities.

#include <iostream>
#include <string>
#include <fstream>
#include <vector>

struct Person
{
    std::string m_firstName;
    std::string m_middleName;
    std::string m_lastName;
    std::string m_maidenName;

    Person(){}
    Person(const std::string& fName, const std::string& midName, const std::string& lName, const std::string& mName)
    : m_firstName(fName), m_middleName(midName), m_lastName(lName), m_maidenName(mName){}
};
std::ostream& operator << (std::ostream& os, const Person& p)
{
    os << p.m_firstName << " " << p.m_middleName << " " << p.m_lastName << " " << p.m_maidenName << '\n';
    return os;
}
int main()
{
    std::ifstream inFile("F:\\test.txt");
    std::vector<Person> persons{};
    if(inFile)
    {
        Person p{};
        while (inFile >> p.m_firstName >> p.m_middleName >> p.m_lastName >> p.m_maidenName)
        {
            if(inFile)
            {
                persons.push_back(p);
            }
        }
    }
    for (const auto& elem : persons)
    {
        std::cout << elem ;
    }

ps: also ignoring the numbers at the end of each row as mentioned but if they are present in a file and not required they can be read into a dummy variable and discarded
