1. With the division (/) operator, what happens if one operand is float and the other is integer? 2. Write a C++ statement equivalent to mass *= force; that does NOT use the compound multiplication assignment operator. 3. Write a C++ relational expression that compares variables peanut and butter to see if they are equal. 4. Convert the following English sentence into a valid C++ boolean expression. Assume that year has been declared to be an integer variable. Use parentheses to show clearly the order of operations you intend. Also, you may use the literal constants 4, 0, 100, and 400 in your answer: "The expression is true if year is divisible by four unless it is divisible also by 100. A year divisible by 100 must also be divisible by 400 for the expression to be true."
