Simple Counting Program

Hey guys, I'm trying to create a program that reads from a text file "mytext.txt" and outputs on the screen the number of lines, characters, and words in the file. I have the lines portion working, but can't think of a way to get each character individually, and words?

Code:

---

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
void main()
{
       
        char line[100];
       
        ifstream infile;
        infile.open("U://mytext.txt");

        if (infile.fail())
       
        {
        cout<<"File not found! Exiting."<<endl;
        exit(0);
        }
        int characters=0, lines=0, words=0;

        while(infile.getline(line, 100))
        {
                lines++  ;
               
        }
        cout<<"The total number of lines in the file is: "<<lines<<endl;
        infile.clear() ;
        infile.seekg(0, ios::beg) ; //so that the beginning of the file is being read again

                while(infile)
        {
                //not sure what to do here?
                characters++  ;
               
        }
       
        cout<<"The total number of characters in the file is: "<<characters<<endl;

}

Maybe there is a better way to do this, but this is just one way I thought of:

Code:

---

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

using namespace std;

int main () {
        string s;
        int totalChars = 0,
                totalWords = 0,
                totalLines = 0;

        ifstream in("test.txt");

        if(!in){
                cout << "Failed to open input file.";
                return -1;
        }


        while(getline(in, s, '\n')){
                totalChars += s.length();
                totalLines++;

                for(int i = 0; i < s.length(); i++){
                        if(s[i] == ' ')
                                continue;

                        totalWords++;

                        while(i != s.length() && s[i] != ' ')
                                i++;
                }

        }

        cout << "Total Words: " << totalWords << endl;
        cout << "Total Characters: " << totalChars << endl;
        cout << "Total Lines: " << totalLines << endl;

                return 0;
}
