There's not much to improve, just that you can declare all data first then the rest of the code for uhh… obvious reasons.

For more ideas, I suggest rather finish learning c++ first. There's much more to it than console I/O

Simple, replace 9/5 with 1.8 and you also don't need double for this table.

Thanks. What's the difference between float and double? On W3Schools it says double is used for floating point numbers. Also, why didn't it work when I put ((celsius * 9) / 5)?

and also putting ((celsius * 9) / 5) didn’t work because celsius is an int, and doing division with and int and an int will round the value down. for example, (int)5 / (int)3 would equal to (int)1, but (int)5 / (double)3.0 would equal to (double)1.666666667,

multiplying an int by a double, which celsius * 1.8 does, will output a double.

Thats why you always write code in an IDE before posting it. Even that joke.
