Write the code to convert the value in an integer variable named count to a double.

C++

static_cast<double>(count)

Step-by-step explanation

Variables are storage containers for data values. In C++, multiple types of variables (specified by distinct keywords) are available, such as int, which saves integers (whole numbers) without decimals, such as 123 or -123. float - stores floating point numbers with decimals, such as 19.99 or -19.99. double - stores floating point numbers with decimals, such as 19.99 or -19.99.

The double data type in C++ is also a primitive data type for storing floating-point numbers up to 15 digits. Variables of the float and double types are initialized with floating-point values in the example above.
