Question

I am reading a text file which contains a word with a punctuation mark on it and I would like to read this word into a string without the punctuation marks.

For example, a word may be ” Hello, ”

I would like the string to get ” Hello ” (without the comma). How can I do that in C++ using ifstream libraries only.
Can I use the ignore function to ignore the last character?

Thank you in advance.

If you only want to ignore , then you can use getline.

 const int MAX_LEN = 128;
 ifstream file("data.txt");
 char buffer[MAX_LEN];

 while(file.getline(buffer,MAX_LEN,','))
 {
  cout<<buffer;
 }

EDIT: This uses std::string and does away with MAX_LEN

ifstream file("data.txt");
string string_buffer;    
while(getline(file,string_buffer,','))
{
  cout<<string_buffer;
}
