Answer 2

Question:-

Write the output of the following code.

Solution:-

Given code,

for(int i=50;i>=5;i=i-5)

System.out.println(i+","+i*i);

Initially, i=50.

The loop executes till the value of i is greater than or equal to 5.

So the number of times loop executes

=50/5

=10

Hence,

Output:-

50,2500

45,2025

40,1600

35,1225

30,900

25,625

20,400

15,225

10,100

5,25
