Question

What is the output of the following code fragment? float "pl pl= new float(3) cout << *pl; a. unknown, the address p1 points to is not initialized b. 0.0 c. 3.0 d. unknown, the code is illegal, p1 points to a dynamic array

Answer 1

c. 3.0

Step-by-step explanation:

The code initializes a pointer to a dynamically allocated float with the value of 3.0. The pointer is then dereferenced using the * operator in the cout statement, which outputs the value stored in the memory location pointed to by the pointer, in this case, the float with the value of 3.0.
