open in append mode otherwise every time a new file will be created and old one overwritten.

is any way to do that with outfile????

why i cant read then

i can write to the file but cannot read?????
writetonsharma (1461)
because you are using ofstream which can only help in writing..
for both use fstream.

this can read as well write. and when you try to write use ios::append. this will append to the old file.
