12 System.out.println("Sum of numbers from 1 to 5 : "+s);

14 }
You will get the following output:
Dry Run & Output
Step Number i s=s+i System.out.println(s);
1 1 0+1=1
2 2 1+2=3
3 3 3+3=6
4 4 6+4=10
5 5 10+5=15 15
Since, the do-while loop executes at least once, we can term it as an Exit Control Loop.
Example of a do-while loop working as an Exit Control loop:
Start
Initialise i = 1
Display "Exit
int i=1;
Control Loop"
do
{
System.out.println("Exit Control Loop");
Increment i by 1
i++;
}while(i<=0);
true Is
i < = 0?
false
Stop
Explanation of the above example: Value of i is 1 and condition to be checked i<=0. This means that the condition
will not satisfy. Since the condition is checked at last, the line System.out.println("Exit Control loop”); will execute
only once.
