My input file is ss7.con which i have to read till the 12th line,if it is not the 12th line ,I have to write it out to the screen,when I reach the 12th line I have to replace the values in the 12th line by those I have put in the hashtable.
The program does the above,but when it reaches the 12th line I have put the values to hashtable,but HOW do I write it to the file and display it on the screen.The final output on the screen must have all the llines in the i/p file includung the 12th line with the new replaced values.
Kindly help me.Thanks.
