Question

Which of these statements convert the contents of the int variable iv to a pointer to a float?

A) float pf = (float)&iv;
B) float pf = static_cast(&iv);
C) float pf = float(&iv);
D) float pf = iv.toFloat();

Answer 1

None of the provided options correctly convert an int variable to a pointer to a float, as direct conversion of an integer address to a float pointer is not allowed in C++.

Step-by-step explanation:

The question is about how to convert the contents of an int variable to a pointer to a float. None of the given options A) float pf = (float)&iv;, B) float pf = static_cast(&iv);, C) float pf = float(&iv);, or D) float pf = iv.toFloat(); are correct for this conversion. This is because in C++ you cannot directly convert the address of an integer to a floating-point number, and also because the syntax used is not appropriate for such casting operations.
