Q:

main()

{

float me = 1.1;

double you = 1.1;

if(me==you)

printf("yes");

else

printf("No");

}

A) Yes B) No
C) Both D) Compilation error
 
Answer & Explanation Answer: B) No

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.
