Why is the output coming 1

Question

int a = 1;
do {
Console.WriteLine(a);
a++;
} while(a < 0);

Answer 1

■ do-while loop always execute the set of code in the do block. then only it check the while condition.

in the give code..
●we initialize a=1.
●then it enter do block and print the value of a as 1. ( console.WriteLine(a))
●then we increment the value of a by one. (a++)
now value of a is 2.
●then it check while condition
while (a <0) that is
○while(2 <0 ) is false
●it exit the while loop

finally the output is 1.

Answer 2

🅰 is equal to 1.

In your code,

You said, print 1.

So it printed 1.

Then you incremented 🅰 by 1.

So 🅰 now is equal to 2. ✔

Then you said,
while(a is less than 0)
repeat the code execution. ♻

But, 🅰 is equal to 2, and 2 is ❌NOT less than 0.

So the code execution stopped. 🚫

And the only number you have printed is 1. 😁

Hope that helps 😁

Answer 3

hello
you are getting 1 because in your "while" you wrote "while a is smaller then 0" and the numbers that are smaller then 0 are negative numbers. You need to change your while condition, set it to a higher number.
