Each element of this array is an array of 4 ints. However, you can assign an ints array of any length to each element. Which of the following values reads the keyboard values in the table? (For example, suppose the size of the array is SIZE.) A) cin >> array[ ]; Why use a named constant for the size of an array? A) int array[ ] = {0,0,0}; (B) int size; size of >> of five; int array[size]; C) const int size = 9; int table [size]; (D) Table int[10]; E) all except B The indexed variables (members) of an array must be integers Which of the following function declarations can be passed to the next table? char myArray[6][8]; A) void f1(char a[ ][ ], int sizeOfFirst); B) void f1(char a[ ][8], int sizeOfFirst); C) void f1(char& a, int sizeOfFirst); D) void f1(char a[6][8], int sizeOfFirst); E) B and D What is the output of the following code fragment? int array[4][4], index1, index2; for(index1 = 0;index1 < 4,index1 ++) for(index2 = 0;index2 < 4,index2 ++) array[index1][index2]=index1 + index2; for(index1 = 0;index1 < 4,index1 ++) { for(index2 = 0;index2 < 4,index2 ++) cost << array[index1][index2] << " "; Cost << Endl; } (1), (3) and (6) are correct. character C1 = 064770; is an octal representation of the integer value 27128, which is legal because it fits into an unsigned 16-bit integer. char c3 = 0xbeef; is a hexadecimal representation of the integer value 48879 that fits in a 16-bit unsigned integer. char c6 = `uface`; is a Unicode representation of a character. (1), (2) and (4) are legal statements. You can use a table declaration to place square brackets to the right or left of the identifier. Option A sounds strange, but it`s perfectly legal to divide parentheses into a multidimensional array and place them on either side of the identifier.
Although programming this way would only annoy your fellow programmers, for the exam you should know that it is legal. It is a collection of variables of the same type used by a common name. What valid declarations exist in an interface definition? For example, suppose you want to create a two-dimensional array of int data. Therefore, you can declare a two-dimensional array in several of the following ways: Which of the following correctly declares an array that can contain up to 3 rows of 5 duplicate columns? (1), (2) and (3) are correct. Interfaces can have constants that are always implicitly public, static, and definitive. Public, static, and final interface constant declarations are optional in any combination. Examples:One-dimensional array declaration of variables: Option C is incorrect because it indicates a legal table declaration, but without initialization. If you need a function that handles multidimensional arrays, you must specify the following quantities in square brackets. If a function expects a pass-by reference parameter, you can pass an index variable from an array of the same basic type to that function.
Option B is the legal way to declare and initialize a five-element array. Table indexes must be smaller than the array size. Create a one-dimensional array and a two-dimensional array without a new operator: A) void f1(int array[ ], const int size); B) void f1(int array[ ], int size); C) void f1 (int & array, int size); D) void f1(const int array[ ], int size); E) void f1(int array[ ], int size) const; The following table declaration is legally double scores[ ] = {0.1,0.2,0.3}; How many indexed variables does the following table have? int myArray[12] = {1,2,3,6,5,4,7,1,2}; A) Table elements can be user-defined types (structures or classes). B) If a function expects a variable of the basic type of the array, you can pass an element from the array to the function. C) all of the above D) none of the above f1 voids (int array[100], int size); void f1(float array[ ], int size); If the index used to access the indexed variables in the array has the value of a non-existent index, it is called ___. Which of the following declares a 5-character array and initializes it with known values? A) char array[5] = {`a`,`b`,`c`,`d`,`e`}; B) char array[4] = {`a`,`b`,`c`,`d`,`e`}; C) char array[5] = {“}; D) char array[ ] = {`a`,`b`,`d`,`e`}; E) A and C Write the declaration for a function called funct1 that expects an array of floating-point numbers and the number of elements in the array and returns no value. while((!found) && (index < numElements)) { if(array[index] == target) found = true; else index ++; } if(found == true) return index; otherwise return -1; } Member declarations in an interface prohibit the use of certain declaration modifiers. You cannot use Transient, Ephemeral, or Synchronized in a member declaration in an interface.
In addition, you should not use private and protected identifiers when declaring members of an interface. What`s wrong with the following code? floating scores[10], total; A) nothing B) Regular and matrix variables cannot be reported together.
