What's the meaning of "priming read" in C program?

Question

I'm doing my C homework and the question want me to use a while-loop with priming read. I don't quite get the meaning,can I have an example for that?

Answer 1

This simply means that you have to initialise the loop variable before entering the loop.

For example:-

Int i=0 //This is priming read or *primer*
While (i<10)
{
i++
}
