Thread: const??

On this board, i've seen people post code and sometimes when they declare a variable, (such as a float or double ect.) they put const befor it. I 'll give you an example...

Code:

const float var;

See what I mean? Please explain this to me somebody.

Thanks

The variable var can not change value. You should also initiate all const declared variables i.e

const float pi= 3.14;

if it's just const float var; then it assigns whatever default value the compiler assigns to it to a constant float value. so, you can't change it.
