Post Challenge

Comments on "Hello, {name}!"

Parent

"Hello, {name}!"

+3
−2

Background

While we do have a "Hello, World!" challenge, we still don't have one regarding input. So let's do one!

Challenge

Create a program that takes an input (not as a function argument) then outputs Hello, , the variable and ! altogether. Standard I/O only applies. Shortest submission per language wins!

Bonus: Use your username as the input.

Dunno what purpose the a[99] serves but it seems to work without the 99.

Shaggy‭ You can't store input in thin air, you need to allocate memory for it. Otherwise the program might crash arbitrary. Also []; isn't valid C.
