Question: 1 / 565

Why are temporary objects created by the compiler automatically const?

To reduce memory usage

To improve performance

To prevent modification of temporary values

When the compiler creates temporary objects, it automatically designates them as "const" to prevent them from being modified. This is because temporary objects are often used for calculations or temporary storage, and modifying them would lead to unintended results in the program. Option A is incorrect because reducing memory usage is not the primary reason for making temporary objects const. Option B is incorrect because improving performance is not the main purpose of automatically assigning const to temporary objects. Option D is incorrect because constant folding can be achieved without automatically making temporary objects const.
