Hey Guys, this my first post and I am quite excited to start learning C for my university course. Just FYI I have no background knowledge, I come from a long education of sports and the natural sciences... so please bare with me.. remember we were all new once.

My question revolves around the use of printing long double floats.

Basically this is my code

#include <stdio.h>
int main(void)

{
double dip = 2.32e-5;
long double trip = 53.232;
printf("%f can be written as %e\n", dip, dip);
printf("%Lf can be written as %Le", trip, trip);
return 0;
}
Eclipse tells me this for my 2nd printf

''Multiple markers at this line
- too many arguments for format [-Wformat-extra-args]
- unknown conversion type character 'L' in format [-
Wformat=]''

and obviously when i see the the output , that particular line is random rubbish (in terms of numbers shown)

What could be the problem?

(also I am using C primer plus by Prata to learn C)
