Set k=1
While k<=5
Display k + 1
End While
In the above what gets displayed
Set k=1
While k<=5
k = k + 2
End While
In the above how many times is the loop executed
For x = 0 To 5
Display x
End For
How many times will the above loop get executed…what will it print
For the first question, the loop runs 5 times, just count it on your fingers. It will display 23456
For the second question, the loop runs three times. Once when k = 1, once when k = 3, and once when k = 5.
For the third question, it will either run 5 or 6 times...I am not familiar with this syntax. If the loop will run when x = 5, then 6 times. If not, then only five.
Also, if it will run when x = 5, then the output will be:
012345
otherwise, it will be:
1234
Hope this helps!
Set k=1
While k<=5
Display k + 1
End While
k does not get updated inside of the while loop, so it will print 2 and loop forever.
Set k=1
While k<=5
k = k + 2
End While
When it hits "while k<=5", the values of k are
1,3,5,7...
So how many times does it get executed?
For x = 0 To 5
Display x
End For
By definition of the for loop, it executes 6 times and displays the 6 integers.
In the first scenario:
- The loop starts with initializing k to 1.
- Then, while k is less than or equal to 5, it executes the following steps:
- Display k + 1
- Increment k by 1 (k = k + 1)
- This continues until k is no longer less than or equal to 5.
So, in this case, the loop will be executed 5 times and it will display the numbers 2, 3, 4, 5, and 6.
In the second scenario:
- The loop starts with initializing k to 1.
- Then, while k is less than or equal to 5, it executes the following steps:
- Increment k by 2 (k = k + 2)
- This continues until k is no longer less than or equal to 5.
Since k is incremented by 2 in each iteration, the loop will be executed 3 times and k will be 1, 3, and 5 after each iteration. So, the loop will be executed 3 times.
In the third scenario:
- The loop iterates from 0 to 5.
- During each iteration, x takes the values starting from 0 and incrementing by 1 until it reaches 5.
- Inside the loop, it displays the value of x.
- This continues until x reaches 5.
Therefore, the loop will be executed 6 times and it will print the numbers 0, 1, 2, 3, 4, and 5.
