How to split the elements of a text file in C++ - c++

Question

i have a text file called builders.txt that contains some data
Reliable Rover:70:1.
Sloppy Simon:20:4.
Technical Tom:90:3.
Within my main file i have a function declaration related to this specific text file
void Builder() {
std:string name;
int ability;
int variability;
}
this is my read file function
std::vector<std::string> lines;
std::string inputFile1 = "Builders.txt";
std::string inputFile2 = "Parts.txt";
std::string inputFile3 = "Customers.txt";
std::string outputFile = "output.txt";
std::string input;
void readFile(std::string const& inputFile1, std::string const& inputFile2, std::string const& inputFile3,
std::vector<std::string>& lines) //function to read Builders, Customers and Parts text file
{
std::ifstream file1(inputFile1);
std::ifstream file2(inputFile2);
std::ifstream file3(inputFile3);
std::string line;
while(std::getline(file1, line))
{
lines.push_back(line);
}
while(std::getline(file2, line))
{
lines.push_back(line);
}
while(std::getline(file3, line))
{
lines.push_back(line);
}
}
This is my attempt
std::vector<std::string> lines;
std::string inputFile1 = "Builders.txt";
std::istringstream newStream(inputFile1);
std::string input;
void readFile(std::string const& newStream,std::vector<std::string>& lines)
{
std::ifstream file1(newStream);
std::string line;
while(std::getline(file1, line,":"))
{
lines.push_back(line);
}
When i run this code i recieve the error "no instance of overload function getline"
My question is given the text file how can i split the text file so that, for example, Reliable Rover is the name, 70 is the ability and 1 is the variability for the 1st record. Another example would be Sloppy Simon being the name, 20 being the ability and 4 being variaiblity. If the question is to vague or requires futher details please let me know
Thankyou

Answer 1

As #thomas-sablik mentioned, a simple solution is to read the file line by line and read each element from the line:
std::ifstream f("builder.txt");
std::string line;
// read each line
while (std::getline(f, line)) {
std::string token;
std::istringstream ss(line);
// then read each element by delimiter
while (std::getline(ss, token, ':'))
std::cout << token << std::endl;
}
don't forget to include sstream for using stringstreams.
Note: refer to cppreference, third parameter of std::getline is delim and is a character but you pass it as a string. So change:
while(std::getline(file1, line,":"))
to:
while(std::getline(file1, line,':'))

Answer 2

Here is a naive approach I came up with:
std::string name;
int ability;
int variability;
char read;
while (ifs >> read) { // read until the end of the file
// adding read into name
while (read != ':') {
name += read;
ifs >> read;
}
ifs >> ability;
ifs >> read; // Remove ':'
ifs >> variability;
ifs >> read; // Remove '.'
// Code to deal with the three variables
name = "";
}
Hope it helps.
