Predict the output or error(s) for the following

Predict the output or error(s) for the following

main()
{
float me = 1.1;
double you = 1.1;
if(me==you)
printf("I love U");
else
printf("I hate U");
}
Answer:



I hate U
Explanation:
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 (== , >, <, <=, >=,!= ) .
