C++ programming language part- 65 Writing and Reading character using binary functions


Writing and Reading character using binary functions

In C++ there are some binary I/O functions such as get(), getline() and read() can be used when the programmer wishes to read white space characters also. The enter file input and output are text- or character-based. Usually , white space cheracter are omitted.




The put() function

The put() and get() functions, which are members of ostream and istream, are used to output and input a single character at a time. The following program writes one character at a time to a file.

Program 46_8
            //inherit.demo
            #include
            #include
            #include // for strlen()

            char cstr[]="Careless Whisper";
            void main()
            {
            ofstream ofil("careless.txt");
            int p;
              for(p=0;p
              {
               ofil.put(cstr[p]);     // put is a member of ofstream
              }
              ofil.put('\0');

            }

            // open this text file and watch information using notepad
