Program/Source Code:

The source code to demonstrate the nested "while" loop is given below. The given program is compiled and executed successfully.

# Ruby program to demonstrate the 
# nested "while" loop

cnt1=2;
cnt2=0;

while cnt1<=5
    cnt2=1;

    while cnt2<=10
        print (cnt1*cnt2)," ";
        cnt2=cnt2+1;
    end

    cnt1=cnt1+1;
    puts;
end

Output:

2 4 6 8 10 12 14 16 18 20 
3 6 9 12 15 18 21 24 27 30 
4 8 12 16 20 24 28 32 36 40 
5 10 15 20 25 30 35 40 45 50

Explanation:

In the above program, we created two variables cnt1, cnt2 that are initialized with 2, 0 respectively. Then we used nested while loop to print tables from 2 to 5.
