I am developing in C/C++ using Visual Studio Community and Visual GDB. When I type things, the intellisense suggestion window covers the code so that I cant see anything. And as I type the windows does not move to the right along with the characters that I have written so far.
Please see the pic I have attached.
Does anyone know how to fix this?

I am afraid that there is no way to resize suggestion window so far. But when you type the windows will change its height automatically along with the characters that you have written. Then you will see the code covered by suggestion window.
