Question

True or False? In C++, the component type of a one-dimensional array cannot be float, double, or long double. True or False? In C++, the index type of a one-dimensional array can be any integral or enumeration type. True or False? The components of an array are all of the same data type. True or False? In C++, an array can be passed as an argument either by value or by reference. True or False? In C++ does not check for out-of-bounds array indexes while a program is running. True or False? If the word cornet precedes the declaration of an array in a function heating, the function is prevented from modifying the array. True or False? The array declared as float angle[1 0][2 5]; has 10 rows and 25 columns. Given the declarations float x [300]; float y[75][4], float z[79]; which of the following statements is true? x has more components than y. y has more components than x. y and z have the same number of components. x and y have the same number of components. a and c above Given the declaration char cable[7][9]; which of the following stores the character 'B' into the fifth row and second column table[4] [1] = 'B'; table[1] [4] = 'B'; table[5] [2] = 'B'; table[2] [5] = 'B'; table[5] = 'B'; Array components often are referred to as array __________

Explanation / Answer

7) True // array declared like array[rows][columus]

8) answer is E

reasion: int a[3][4] = {
{0, 1, 2, 3} ,
{4, 5, 6, 7} ,
{8, 9, 10, 11}
}; from the example if the array has X-rows and Y- columns, it can accommodate X*Y values

so X[300]=X[75][4] both can accomodate 300 values.

so answer A) X has more components than Y and answer D) X and Y have the same number of components

so final answers is both A and B so Answer is E.

9) Answer is C. i.e table[5-row][2-columns]
