Assume a program has the following variable definitions int a, b = 2; double c = 4.3; and the following statement: a = b * c; what value will be stored in a? assume that qty and sales reps are both integers. use a type cast expression to rewrite the following statement so it will no longer perform integer division. unitseach = qty/salesreps; rewrite the following variable definition so the variable is a named constant with the value 12. int rate; are deliberately missing. replace the following statements with a single statement that initializes sum to 0 at the time it is defined. int sum; sum = 0; is the following code legal? why or why not? const int days in week; days_in_wkek = 7; are deliberately missing.
