Answer

1 2 3 4 5

Explanation:

initialize the value of n with 1

then, for loop is executed until the condition is true.

so, it check the condition 1<=5, condition true, code is executed and print 1

and n become 2.

again check condition 2<=5 condition true, code is executed and print 2

and n become 3.

and so on....

it print 1 2 3 4 5 after that check condition 6<=5 condition false, it terminate from loop.

Therefore, the answer is  1 2 3 4 5
