What does command nextline actually do?

Answer 1

@Aarnav Saxena See the following examples. In this case, '_' represents where the cursor is.

write("Hello");
write(" World");
[Outputs: Hello World_]

The comand write just displays text and leaves the cursor on the same line.

writeln("Hello");
writeln(" World");
[Outputs: Hello
World
_]
The command writeln displays text and moves cursor to the next line.

Hope this explains! ☺
