Question:Which of the following operations are INCORRECT? 

A int i = 35; i = i%5; 
B short int j = 255; j = j; 
C long int k = 365L; k = k; 
D float a = 3.14; a = a%3; 

+ Answer
D 

+ Explanation
float a = 3.14; a = a%3; gives "Illegal use of floating point" error.

The modulus (%) operator can only be used on integer types. We have to use fmod() function in math.h for float values.
