I had read a line. It is:

Question

while(1==scanf("%s",&country))
{
}

What does it mean?

Answer 1

scanf return amount of value read in from the buffer, in your case it will be 1 if it's more than 1, it will go outa the loop, why not try it in a code and see for yourself that will yield a better understanding for you

Answer 2

I tried. But did not understand how a string can be equal to 1. 😔
