When i trying to read from file text, occurs numerics and letters
This is my GreenLang.cpp:

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

class ScanErrors {
protected:
    char* element;
    char codeElement;
    std::string path;
    std::string source;

public:
    ScanErrors (std::string filePath) {

        std::ifstream fileRead;
        fileRead.open(filePath);
        while (!fileRead.eof()) {
            fileRead.get(codeElement);
            scan(codeElement);
        }
        fileRead.close();
    }
    
    void scan(char code) {
        std::cout << code << std::endl;
        std::cout << std::to_string(code);
    }
};

int main() {
    ScanErrors scanner("code.gl");

    return 0;
}

This is my code.gl:
Hello, World!

My output:
H
72e
101l
108l
108o
111,
44
32W
87o
111r
114l
108d
100!
33!
33
Why these weird numerics appears?

>Solution :

If you want to print only the characters and not their ASCII values, you can remove the line std::cout << std::to_string(code); from your scan function:

void scan(char code) {
    std::cout << code << std::endl;
}
