Arrays should be passed by reference or by pointer, never by value (passing by value passes a copy of the reference, not the reference itself). The array length should also be passed to the function (by constant value) to prevent buffer overflows. Alternatively, in object-oriented languages, arrays can be wrapped in a class of object. Since the array is a member of the class, it doesn't need to be passed to the member methods, thus the function can become a member method of the class itself or a derivative of the class. Or the object containing the array can be passed to external functions by reference.

What happen when a c program passes an array as a function argument?
When an array name is passed as a function argument, the address of the first element is passed to the function. In a way, this is implicit call by reference. The receiving function can treat that address as a pointer, or as an array name, and it can manipulate the actual calling argument if desired.
What does array map do in php?

How is an array name interpretedwhen it is passed to a function?
An array is still an array, regardless of how you pass it into functions. It is still an array-type variable at the beginning of a function. However, the function itself may manipulate the array by "imploding" it into a string with a delimiter, using array values with only specific keys, and such.
Argument Array in java script?
There is an arguments object in JavaScript. This object is treated much like an array (but it's not actually an array.)You can however reference the arguments passed to a function via this array. For instance, if we call a function like so:exampleFunc('Tom', 15, 'potato');Then we can access the value of Tom at the local variable arguments[0].
