Hi, I am trying to read each character from a file in c++, also,I need to get their ascii value, but I have a problem on the output, there are two characters else I dont need, even I don´t why they appear.
Here is the code and the output, thanks a lot.

#include <iostream>
#include<fstream>

using namespace std;

int main()
{
ofstream wfile("Ej_01.txt");
wfile<<"AbCd"<<endl;
wfile.close();

ifstream lfile;

lfile.open("Ej_01.txt");
char word;
int temp;
while(lfile.good()){
lfile.get(word);
temp=word;

cout<<word<<" "<<temp<<endl;



}

cout<<endl;

lfile.close();


return 0;


}




And this is the output:

A 65
b 98
C 67
d 100

10

10

Press <RETURN> to close this window...




So How can I get the same result without de last two '10'??

Character '10' is the ASCII code for newline. They are part of the file.

If you don't want to see them, either ignore them or supply a file without any newlines.

Hope this helps.

Thanks, I understand it better, but I still have a little problem: It is reading twice the last caracter, so now this is the output:

A 65
b 98
C 67
d 100
d 100
Press <RETURN> to close this window...


As you can see...It prints (d 100) twice

Check for input failure after (not before) attempted input.

#include <iostream>
#include <fstream>
#include <cctype>

int main()
{
    std::ifstream file( __FILE__ ) ;

    char c ;
    while( file.get(c) ) // exit the loop if input failed (no more characters in the file) 
    {
        if( std::isprint(c) ) std::cout << c << ' ' << int(c) << '\n' ;
    }
}
