TRUE/FALSE The indexed variables (members) of an array must be integers. ANSWER: FALSE The locations of the various indexed variables in an array can be spread out all over the memory. ANSWER: FALSE The following array declaration is legal double scores[]={0.1,0.2,0.3}; ANSWER: true Arrays can be passed to functions. ANSWER: TRUE Arrays can be returned from a function. ANSWER: FALSE If a function is expecting a pass by reference parameter, you can pass an index variable from an array of the same base type to that function. ANSWER: TRUE When you have a function that expects an array, it should also expect the size of the array or the number of indexed variables with valid data. ANSWER: TRUE The following function declaration guarantees the values in the array argument are not changed. void function1(int array[], int numElements); ANSWER: FALSE The following function will work with any size integer array. void function1(int array[], int numElements); ANSWER: TRUE If you use the const modifier in a function declaration, you do not include it in the function definition. ANSWER: FALSE Short Answer Write the code to declare a two dimension array of integers with 10 rows and 20 columns. ANSWER: int array[10][20]; Write the code to declare an array of 10 doubles named list; ANSWER: double list[10]; The modifier that guarantees that an array argument will not be changed is called ______. ANSWER: const How many indexed variables does the following array have? int myArray[]={1,2,3,6,5,4,7,1,2}; ANSWER: 9 How many indexed variables does the following array have? int myArray[12]={1,2,3,6,5,4,7,1,2}; ANSWER: 12 Write the declaration for a function named funct1 that expects an array of floats, the number of elements in the array and does not return any value. ANSWER: void funct1(float myArray[], int numElements); If you put a value in the square brackets of a one-dimension array parameter, this value is _________ by the compiler. ANSWER: ignored If your index used to access the in
