It works fine machan. What compiler are you using?

Iam using visual studio .. Ya It works fine. But while entering a Row number giving some errors ..

 

[Ashhab]

menna machan error eka

"Run-Time Check Failure #3 - The variable 'row0' is being used without being initialized."

 

[DJvodka]

In case 2: whats the use of following lines? I think you should remove them.
row0;
row7;
row8;
