Is the output od the following program, right? Is it common to include the increment before the other statements in a loop?

Question

int num = 1;
while (num < 6) {
num = num + 1;
cout << "Number: " << num << endl;

}

/* Outputs

Number: 2
Number: 3
Number: 4
Number: 5
Number: 6
*/

Answer 1

Yeah, doing:
cout << "Number: " << ++num << endl;
Will result in the same output.

Answer 2

it makes no real difference

Answer 3

Locating the Incremental value is based on the requirement. Usually while loop holds the increment/decrement at the end of the loop.

Here we missed the output for value '1'.
