Question

How many times will the loop iterate, if the input is 105 107 99 103? cin >> x; while (x > 100) { // Do something cin >> x; }

Answer 1

Answer:

well since only 3 out of the 4 values are above 100 it would go 3 times and before your program returns to 0.

Answer 2

Answer:

Two times

Explanation:

Required

Determine the number of iteration of the loop

The first line: cin>> x; gets input for x

$x = 105$

The while loop: while x > 100 is true because 105 > 100

So, the loop will be iterate as thus:

cin>>x:

Here, $x = 107$

The while loop: while x > 100 is true because 107 > 100

So, the loop will iterate for the second time as thus:

cin>>x:

Here, $x = 99$

The while loop: while x > 100 is false because 99 < 100

Hence, the loop will not iterate.

Number of iteration = 2
