Answer 2

Answer :

note :  

strrev ( ) function is used to reverse a string.

cout is an output stream which is used to show output.

cin is an input stream which is used to take input.  

Input.txt is a text file according to the question.

void RevText (  )  // this is a function

{

ifstream Fin ( “ Input.txt ” );

char W [20];

while ( ! Fin.eof ( ) )  

{

Fin >> W ;

if ( W [ 0 ] == ’ I ’ )

strrev ( W );

cout << W <<  “  ”  ;

}

Fin. close (  ) ;

}
