Why the keyboard 'const double' not 'const'?

You need to specify that what type of data is going to be constant. For eg- const int x = 10; const double y = 22.45;

Constants A constant stores a value that cannot be changed from its initial assignment. By using constants with meaningful names, code is easier to read and understand. To distinguish constants from variables, a common practice is to use uppercase identifiers. One way to define a constant is by using the const keyword in a variable declaration: 》》》I am asking about this constant but in code... const double.. is used

shridhar w that's what I have mentioned, you can create constants like that and their value cannot be altered in the code. For eg take the value of PI which is a constant.
