Question

Which of the following loops will print out the numbers 5, 10, 15, 20, 25?

I.
int i=5;
while(i<=25)
{
System.out.println(i);
i=i+5;
}

II.
for(int i=5;i<=25;i=i+5)
{
System.out.println(i);
}

III.
for(int i=4;i<24;i=i+5)
{
System.out.println(i+1);
}

Answer 1

All the given loops, I, II, and III, correctly print out the sequence 5, 10, 15, 20, and 25 as per their respective initialization and incrementation patterns.

Step-by-step explanation:

The question is about identifying which of the provided loops in a programming language (presumably Java, based on the syntax) will print out the numbers 5, 10, 15, 20, 25. Let's analyze each loop:

I. While Loop

int i=5; while(i<=25) { System.out.println(i); i=i+5; }

This while loop starts with i initialized to 5 and increments i by 5 on each iteration, as long as i is less than or equal to 25. This loop will indeed print out 5, 10, 15, 20, 25 as required.

II. For Loop

for(int i=5; i<=25; i=i+5) { System.out.println(i); }

This for loop also initializes i to 5 and increments i by 5 on each iteration, stopping once i exceeds 25. This loop also meets the conditions and will print out the sequence 5, 10, 15, 20, 25.

III. Modified For Loop

for(int i=4; i<24; i=i+5) { System.out.println(i+1); }

This loop initializes i to 4 and adds 5 to i on each iteration, but it prints out i+1. This results in the series 5, 10, 15, 20, 25 being printed, fulfilling the condition as well.

All loops I, II, and III will print out the numbers 5, 10, 15, 20, and 25 successfully.
