The Const

In the c, c, d, javascript and julia programming languages, const is a type qualifier a keyword applied to a data type that indicates that the data is read only. While this can be used to declare constants, const in the c family of languages differs from similar constructs in other languages in being part of the type, and thus has complicated behavior when combined with pointers, references, composite data types, and type-checking.

The Const

So in your question, int const means that the int is constant, while int const would mean that the pointer is constant. If someone decides to put it at the very front (eg const int ), as a special exception in that case it applies to the thing after it. Many people like to use that special exception because they think it looks nicer.

Javascript const es6 introduced the const keyword, which is used to define a new variable in javascript. Generally, the var keyword is used to declare a javascript variable. Const is another keyword to declare a variable when you do not want to change the value of that variable for the whole program.

Because of this, we cannot change constant primitive values, but we can change the properties of constant objects.

Declaring constants (VBA) | Microsoft Docs

  variables can be declared as constants by using the const keyword before the datatype of the variable. A program that demonstrates the declaration of constant variables in c using const keyword is given as follows.

  you use the const statement to declare a constant and set its value. After a constant is declared, it cannot be modified or assigned a new value. You can declare a constant within a procedure or at the top of a module, in the declarations section.

It is a variable qualifier that modifies the behavior of the variable, making a variable read-only. This means that the variable can be used just as any other variable of its type, but its value cannot be changed. You will get a compiler error if you try to assign a value to a const variable.
