What is the output?

Question

int i=5;
for(int i=0; i<7;i++){ }
cout<<i;. //answer is 5 why not 7?

Answer 1

5. Because the loop variable i is declared inside the loop and can only be accessed within the loop. So when you are trying to access i outside the loop, it will refer the first i which was declared outside.

Answer 2

thank you so much shamima and naitomea

Answer 3

It should be 5, because the 'i' in the for-loop has only a local range and won't affect the 'i' declared in main function.
