${LDS_FILE} what is the difference between { and ( ?

In programming, the curly brace `{}` is typically used to enclose a block of code, such as in functions, loops, and conditional statements. On the other hand, parenthesis `()` are often used to enclose arguments in function calls or mathematical expressions.

For example, in C++ or Java, a function definition might look like this:

int myFunction(int arg1, int arg2) {
    // code block enclosed in curly braces
    int result = arg1 + arg2;
    return result;
}

In this example, the curly braces define the beginning and end of the function's code block.

In contrast, a function call might look like this:

int x = myFunction(3, 5);

In this example, the arguments `3` and `5` are enclosed in parentheses, indicating that they are being passed as arguments to the `myFunction` function.
