validation

[omnius]

I have a defined a char of size 6

How can i validate the input so if a user enters 7 or more characters then an invalid size is shown and it will not override os memory.

Code: Select all

char product[6];

cout<<"enter product: ";
cin>>prod;



One way would be to use the std::string class, which overcomes many of the limitations of using character arrays for strings.

You can limit the input to your char array with:

cin >> setw(6) >> prod;

Try this.

cin.get(6, product);

My advice is that after you get this input to write the following:

cin.get(); //this u use to clear the input stream.

My advice is that after you get this input to write the following:

cin.get(); //this u use to clear the input stream.

That will block waiting for input with an Enter key press rather than clear the input stream directly. You can use cin.ignore() to clear the input stream - a quick search through the forums should find examples of how to do so.
