What is the result type of an integer division between 10 and 4 in C++?

In C++, when you perform an integer division between two integers, such as 10 and 4, the result type of that operation is an integer. This is because both operands are of the integer type, and C++ follows the rule of truncating the fractional part of the result when using integer division.

In this case, dividing 10 by 4 gives you a mathematical result of 2.5, but since both numbers are integers, C++ truncates the decimal portion, resulting in an output of 2 as an integer. This behavior is intrinsic to how integer arithmetic is defined in C++, ensuring that the resulting type remains consistent with the types of the operands involved in the operation.

Other options reference different types of data that are not relevant to the result of this division operation. For instance, float and double represent floating-point numbers which can include decimal portions and are generally derived from at least one floating-point operand. An array refers to a collection of elements, which is not applicable in this simple division context. Thus, the only suitable result type for the operation described is indeed an integer.
