Correct Option: A
When an array is declared using new operator then all of its elements are initialized to 0 automatically. for loop body is executed 10 times as whenever controls comes in the loop i value is incremented twice, first by i++ in body of loop then by ++i in increment condition of for loop.
output: 0 2 4 6 8 10 12 14 16 18
