Answer 1

You shouldn’t test for exact equality of floating point values. Also 0.7 is treated as a double, which uses more bits for precision. In your code you are comparing two different types.

Answer 2

Yes it will print hii because
float a = 0.7;

The value of a is float type but the type of 0.7 is double and double size precision more than float values .
By default decimal values are float types if u want to make it float type then u have to write float a=0.7f dont .
Hope you understood

Answer 3

no. you will have to handle that conversion yourself. if you need, you can write a float by adding “f” to the end of a number: ‘12.6f’ would be a floating point.

Answer 4

Brian R That is to say C won't change num's type when comparing, right?

Answer 5

Brian R Thanks. So C won't do conversion and allows comparing between different type. I think it shouldn't happen. In my opinion, it may cause many bug.
