Question

How does a FOR loop start?

a) for i = 1 to 5
b) for (i = 0; i <= 5)
c) for (i = 0; i <= 5; i++)
d) for (i <= 5; i++;)

Answer 1

The correct way to start a FOR loop is option c) "for (i = 0; i <= 5; i++)", which initializes a counter, checks a condition, and increments the counter in each loop iteration.

Step-by-step explanation:

The correct way to start a FOR loop in most programming languages such as JavaScript, C, C++, and Java is option c) for (i = 0; i <= 5; i++).

This syntax is divided into three main parts:

• Initialization: It begins with the variable initialization i = 0. This is where we start counting from.
• Condition: The next part is the loop condition i <= 5 which determines how long the loop will run. In this case, the loop will run as long as i is less than or equal to 5.
• Increment: Finally, the incrementation i++ means that we increase i by one each time the loop iterates.

This loop structure is commonly used in programming to repeat a set of instructions a specific number of times.
