Final answer:
The expressions yield the following results: 7/2, static_cast(7)/2, 7/2.0, static_cast(7/2) all give the value 3.5, 7%2 gives the remainder 1, (4+3)/2 also results in 3.5.
Step-by-step explanation:
The value of each of the following expressions:
- a. 7 / 2: This yields 3.5 when using calculator division in mathematics. It implies the division of seven by two.
- d. static_cast(7) / 2: In programming, particularly in C++ or similar languages, static_cast converts an integer to another data type before the division, the result remains 3.5 since static_cast doesn't change the value here.
- b. 7 / 2.0: Here, the division includes a floating-point number (2.0), which forces floating-point division. As a result, the answer is also 3.5.
- e. static_cast (7 / 2): This is an example of static casting in programming, which typically occurs after the arithmetic operation. Since 7/2 is integer division, the result is 3, which may be cast to another type without changing its value.
- c. 7 % 2: The modulus operator returns the remainder of the division of 7 by 2, which is 1.
- f. (4 + 3) / 2: Parentheses alter the order of operations, making it addition followed by division. The sum inside the parentheses is 7, divided by 2 results in 3.5.
