How many times would the following loop iterate?
For j = 1 To 5 Step 2
Display j
End For
A) 4
B) 5
C) 3
D) 0
Answer (1)
The question involves understanding how a loop functions in a programming context. Here, we are looking at a For loop that is commonly found in programming languages.
The loop is structured as follows:
For j = 1 To 5 Step 2 Display j End For
Let's break down how this loop works:
Initialization : The loop starts with the initial value j = 1.
Condition : The loop will continue to iterate as long as j is less than or equal to 5.
Increment : The Step 2 means that after each iteration, j will increase by 2.
Iterations :
1st Iteration : j = 1. The condition is true since 1 <= 5. So, it displays 1.
2nd Iteration : j = 1 + 2 = 3. The condition is true since 3 <= 5. So, it displays 3.
3rd Iteration : j = 3 + 2 = 5. The condition is true since 5 <= 5. So, it displays 5.
4th Iteration : j = 5 + 2 = 7. The condition is NOT true since 7 > 5. The loop stops here.
Since the loop iterates three times (with j taking on the values 1, 3, 5), the correct answer is C) 3 .
The loop effectively runs three times before j exceeds the value 5, which makes option C the correct choice.
