6. (6 points) One way to force a one time data type conversion is to use the static_cast conversion. Take for example the following code snippet: int number 7; int denom = 5; double varl = number / denom; double var2 = static_cast(number) / denom; int var3 = static_cast(number) / denom; a. (3 points) Would you expect var1, var2, and var3 to be equal to each other? Why or why not? b. (3 points) Write a function definition for a function that takes one argument of type int and one argument of type double, and returns a value of type double that is the real number average of the two arguments
