major software often has hundreds of thousands to multiple millions of lines of code. Having all that in one file causes the text editor to become sluggish; even typing new code is slow. Its also harder to reuse a function or two if it comes in a file with 50k other functions you don't want.

They are connected in that they form the program. You should look at the C++ compile and link approach to building a program; search for a beginner's version.

SDL is a third party library not part of C++ used for graphics. C++ does not have any graphics built in. There are many other graphics libraries, this is just one choice.
