Placement Question-2

What is the output of the following program ?

float me = 1.1;
double you = 1.1;

printf("I love U");


printf("I hate U");

I hate U

For floating point numbers (float, double, long double) the values
cannot be predicted exactly.
Depending on the number of bytes, the precession

with of the value represented varies. 
Float takes 4 bytes and long double takes
10 bytes. So float stores 0.9 with less precision than long double.
Rule of Thumb:
Never compare or at-least be cautious when using floating point
numbers with relational operators (== , >, <, <=, >=,!= ) .
