Which of following expression(s) is an example of type casting(a) 4.0 +float(6) (b)5.3 +6.3 (c) 5.0 +3 (d) int(3.1) +7

Type casting is the process of converting one data type to another.

(a) 4.0 + float(6): This is an example of type casting. The integer 6 is being cast to a float before the addition operation.

(b) 5.3 + 6.3: This is not an example of type casting. Both numbers are already floats, so no type conversion is necessary.

(c) 5.0 + 3: This is not an example of type casting. The integer 3 is implicitly converted to a float by the Python interpreter, but this is not an explicit type cast.

(d) int(3.1) + 7: This is an example of type casting. The float 3.1 is being cast to an integer before the addition operation.

So, the expressions (a) and (d) are examples of type casting.
