thank you so much.

actually i messed the whole program.
i choosed the wrong variables. due to inproper variable selection
i used cin<< instead if cin>>

actually, its been only 3 days since i started learning c++ from the book my senior students gave me.
so i didnt know the function of 'std'
anyway thanxx for your help
and please dont tell me about 'std' i want to learn c++ step by step ..

regards
