Should I avoid casting between data types?
I haven't really seen much about the use of this, but it seems like one of those last-minute-no-way-around kind of methods... but, for example, how would I use the length of a string in a for loop? The length property of a string is size_t, and if I had an integer i in a loop, how could I do that?
Where would casting be useful? Where should I avoid it? What are other methods of dealing with different data types that are better than cast?

Into the midnight giving it to you, I don't know it just feels right.
