What will you do to treat the constant 3.14 as a long double?

[A].	use 3.14LD	[B].	use 3.14L
[C].	use 3.14DL	[D].	use 3.14LF

Answer: Option B

Explanation:

Given 3.14 is a double constant.

To specify 3.14 as long double, we have to add L to the 3.14. (i.e 3.14L)

Can anyone explain this in detail that how it works if anyone understand?

For the long double Lf is used as suffix then how L is used?

@Ashish No its totaly wrong. For long double 'L' is used as suffix.

long double: %LF or %Lf double :%lf float:%f or %e or %g int :%i or %d long int:%ld or %li unsigned long:%lu unsigned int:%u

What exactly difference between double & long double & int?

The double is used for floating 44.45, int for integers like 2,567etc , long double for large floating values like 6.98765342 .

For the long double LF is used in c.

Double is also like floating point but having size of 4 bytes,double has 8 bytes,long double has 10 bytes and integer has 2 bytes.So long double can store larger floating points also.Here 3.14 is a long double.
