Which of the following data types can be used in a switch controlling expression? int, char, and enum int Question 29 \( \begin{array}{l}\text { If you want a loop to quit iterating if } x<10 \text { and } y>3 \\ \text { what would be the proper loop condition test? }\end{array} \) \( \begin{array}{l}(x>10 \| y<3) \\ (x \geq 10 \| y \leq 3) \\ (x<10 \& \& y>3) \\ (x \geq 10 \& \& y \leq 3)\end{array} \) When testing a program with a loop, which of the following tests should be done? no iterations of the loops one less than the maximum number of iterations no iterations of the loops, one less than the maximum number of iterations, and the maximum number of iterations the maximum number of iterations one more than the maximum number of iterations The ___ operator could be used, in some situations, to simplify nested selection structures. NOT AND OR All of these None of these In the function declaration shown, the mechanism used to call this function is known as: double pow(double base, double exp). pass by name call by value by name pass by value When overloading a function, what must be true? The names should be the same with different number and/or types of parameters. The names should be different with the same number and/or types of parameters. The names should be different with different number and/or types of parameters. The names should be the same with the same number and/or types of parameters. When parameters are passed between the calling code and the called function, parameters and arguments are matched by their relative positions in the parameter and argument lists. their data types. their names. They are not matched up at all.
