Which of the following is not a property of a constructor?A. The name of a constructor can be chosen by the programmerB. A const

inna [77]

Answer:

The answer is "Option A"

Explanation:

The constructor is a special member function whose task is to initialize an object from its class, and it doesn't return any value like int, float, double, etc. Its name and class name will always be the same, and when we create the class object so, the constructor is automatically called, and it may be overloaded, that's why we can say that except the "choice A", all were correct.

Write the definition of a function named swapints that is passed two int reference parameters. The function returns nothing but

Alja [10]

Answer:

void swapints(int *j,int *k)//Function definition.

{

*j=*j+*k-(*k=*j); //value swapping.

}

swapints(&j,&k);//call the function.

Explanation:

The above function definition takes the address of j and k variables which is stored on the pointer variable j and k.
Then the pointer variable uses the j and k value for the above expression, and the user does not need to return the value of j and k.
But when the user prints the value of the j and k variable, then he gets the swapping value of the j and k variable.
The user needs to know that the "int j" is a normal variable, but "int *j" is a pointer variable that is used to take the address of j variable.
