Floating Point Issues - Find Output of Program :: Discussion

9.	What will be the output of the program?
	A.	2.2, 2.50, 2.50, 2.5
	B.	2.2e, 2.25f, 2.00, 2.25
	C.	2.250000e+000, 2.250000, 2.25, 2.250000
	D.	None of above

	Answer: Option C


	Explanation:
	printf("%e,", d); Here '%e' specifies the "Scientific Notation" format. So, it prints the 2.25 as 2.250000e⁺⁰⁰⁰. printf("%f,", d); Here '%f' specifies the "Decimal Floating Point" format. So, it prints the 2.25 as 2.250000. printf("%g,", d); Here '%g' "Use the shorter of %e or %f". So, it prints the 2.25 as 2.25. printf("%lf,", d); Here '%lf' specifies the "Long Double" format. So, it prints the 2.25 as 2.250000.
