Right to Left Associativity of Operators

In programming languages, associativity determines the order in which operators of the same precedence level are evaluated. There are three types of associativity: left to right, right to left, and non-associative.

Right to left associativity means that the operators are evaluated from right to left. This means that the rightmost operator is evaluated first, followed by the operator to its left, and so on.

Among the given options, only the type cast operator has right to left associativity.

Explanation:
The type cast operator is used to convert one data type to another. It has the highest precedence among the operators. When used, it is written as `(type) expression`. The expression inside the parentheses is converted to the specified type.

Example:
```
int a = 10;
double b = (double) a;
```
In the above example, the expression `a` is cast to a double using the type cast operator `(double)`. The result is stored in the variable `b`. The type cast operator has right to left associativity, so the expression `(double) a` is evaluated first, converting the integer value 10 to a double value 10.0.

Associativity of Other Operators:
- Array subscripting operator: The array subscripting operator `[]` is used to access elements of an array. It has left to right associativity. For example, `array[3]` accesses the element at index 3 of the array.
- Function call operator: The function call operator `()` is used to call a function and pass arguments to it. It has left to right associativity. For example, `function(arg1, arg2)` calls the function `function` with arguments `arg1` and `arg2`.
- Addition and subtraction operators: The addition `+` and subtraction `-` operators have left to right associativity. For example, `a + b - c` is evaluated as `(a + b) - c`.

In conclusion, among the given operators, only the type cast operator has right to left associativity.
