B and C are different types, an integer and a floating point number. How can you expect them to be equal?

When printing f, do not add&; Scanf needs to be added.

# Contains? & ltstdio.h & gt

# Contains? & ltmath.h & gt

int？ main()？ {

int？ First,? c；

Floating? b；

Printf ("input? No.: \ n ");

scanf("%d "，& ampa)；

b？ =? sqrt(a？ +? 256.0);

c？ =? sqrt(a？ +? 256.0);

printf("%d\n%lf\n "，c，b)；

printf((b？ ==? C) "this? Is it? It's \n ":"This? Is it? No \ n ");

Return? 0;

}
