- 1 2 3 4 5
- 0 1 2 3 4 5 6 7 8 9 10
- 1 2 3 4 5 6 7 8 9
- 0 1 2 3 4 5
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 5 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: 1 2 3 4 5 6 7 8 9 10
