Option(d) i.e "storing a float in an int" is the correct answer for the given question.
Explanation:
Typecast is used for the changing the one datatype to the another datatype Their are two types of casting
1 implicit
In this typecast we change the smaller datatype into the larger datatype.
For example
int to float
2 Explicit
In this typecast we change the larger datatype into the smaller datatype in an explicit manner.
For example
float to int.
in the given question we required the casting in the option(d) i.e "storing float in an int" That's why this option is correct and all other options are incorrect.
