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

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)

 Ashish said: (Fri, Dec 3, 2010 04:12:31 AM) For the long double Lf is used as suffix then how L is used?

 Aparna said: (Wed, Mar 2, 2011 09:36:57 AM) @Ashish No its totaly wrong. For long double 'L' is used as suffix.

 Chaitanya said: (Thu, Aug 4, 2011 10:56:56 AM) 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

 Harshareddy said: (Tue, Jan 3, 2012 10:12:33 PM) The double is used for floating 44.45, int for integers like 2,567etc , long double for large floating values like 6.98765342 .

 Rajesh said: (Fri, Jan 27, 2012 04:10:19 PM) For the long double LF is used in c.

 Sri Ram said: (Sat, Sep 1, 2012 03:48:35 PM) 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.
