Ya. I need some textboxes.. the number of textboxes is dynamic. So right now, i have put them in a loop and called them text1,text2,etc
SO jsp puts the values in sepearate strings, text1,text2,etc .. Would it be possible to change this to an array or list.....Leave a comment:

Well. c++ does use char* v
Looks like you haven't learnt about pointers. i suggest you read about them.

char *v is how you declare a pointer to a character. here *v will contain the memory location[and not the value of the character]. This memory location will contain a single character....Leave a comment:
