Write a program segment to print the values of each element of array table in tabular format with 3 rows and 3 columns.

Assume that the array was initialized with the declaration

int table[ arraySize ][ arraySize ] = { { 1, 8 }, { 2, 4, 6 }, { 5 } };

and the integer variables i and j are declared as control variables.

Выберите один ответ. a. cout << " [0] [1] [2]" << endl;

for ( int i = 0; i < arraySize; i++ ) {

cout << '[' << i << "] ";

for ( int j = 0; j < arraySize; j++ )

cout << setw( 3 ) << table[ i ][ j ] << " ";

cout << endl;

b. cout << " [0] [1] [2]" << endl;

for ( int i = 0; i < arraySize; i++ ) {

cout << '[' << i << "] ";

for ( int j = 0; j < arraySize; j++ )

cout << setw( 3 ) << table[ i ][ i ] << " ";

cout << endl;
