[amp_mcq option1=”(double) amount” option2=”(int to double) amount” option3=”int to double(amount)” option4=”int (amount) to double” correct=”option1″]
The correct answer is: A. (double) amount
A type cast is a way to explicitly convert a value from one type to another. In this case, we want to convert an Integer variable named amount to a Double type. The correct way to do this is to use the type cast operator (double), which is placed before the variable name. For example:
double amount = 10;
double convertedAmount = (double) amount;
The type cast operator will convert the value of the variable amount to a Double type. The value of the variable convertedAmount will be 10.0.
The other options are incorrect. Option B, (int to double) amount, is not a valid type cast. Option C, int to double(amount), is not a valid type cast. Option D, int (amount) to double, is not a valid type cast.
