Problem Solution:

In this program, we will print numbers from 1 to 5 using for loop, while, and do while loop. Here, we use a counter variable to iterate numbers.

Program/Source Code:

The source code to print numbers from 1 to 5 using for loop, while, and do while loop is given below. The given program is compiled and executed successfully.

```# Ruby program to print numbers from 1 to 5
# using the for loop, while, and do loop

puts "For Loop:";
for cnt in 1..5 do
print cnt," ";
end

puts "\nWhile Loop:";
cnt=1;
while cnt<=5
print cnt," ";
cnt = cnt + 1;
end

puts "\nDo While Loop:";
cnt=1;
loop do
print cnt," ";
if cnt==5
break;
end
cnt = cnt + 1;
end
```

Output:

```For Loop:
1 2 3 4 5
While Loop:
1 2 3 4 5
Do While Loop:
1 2 3 4 5
```

Explanation:

In the above program, we used while, do, and for loop to print numbers from 1 to 5.
