String I/O

Ordanary  Input and Output of string from more straightforward methods are described here. remember setting *word which is the same as word[0] and *word to .\0' and stopping the loop. The expression *word controls the loop. it is the initial values character in the string. it will be nonzero(i.e., "true") as long as the word   contains a string of length grater than 0. The string of length 0, called the empty string, contains tht NULL character '\0' . Pressing Control+D on a UNIX machin or Control+Z on a DOS machine sends the end-of-file character in from cin.

Program 29-9

            {char word[50];

            do

            {

               cin>>word;

            if (*word)

            cout<<"\t\""<

            } while (*word); }       // be care

Note: type atleast 100 letters within a sentence.

             void main()

            { char ch,pre='\0';

            while (cin.get(ch))

            {

            if (pre==' ' ||pre=='\n')

            cout.put(char(toupper(ch)));    // Boolean function
