Yes. Since passing arrays is a special use of call by reference, simply pass the address of the sub array instead of the primary array.
int a[10] = { ... };
myfunction (a); // pass the first element's address
myfunction (&(a[3]); // pass the fourth element's address

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.
When is it better to pass an entire array of data to a function rather than individual elements?
It is better to do this when the function needs to work on the entire array, rather than on individual elements. However, do not pass the array by value; always pass by reference.
How you pass array elements to a function?
Passing array elements to a function is achieved by passing the individual elements by reference or by value, just as you would any other variable. However, passing the entire array requires that you pass a pointer-to-pointer to the array along with the dimension(s) of the array.
Can you pass addresses to a function in C plus plus?
If the identifier you want to pass is an ordinary identifier, pass it as the address of... function(&identifier); If the identifier you want to pass is an array identifier, pass its name... function(arrayname);
How do we pass array to function of java?
Let the function be private void processArray(int[] arInts); to call this 1. Create a local array variable, set the values and pass it int[] arIntInp = {0,1,3}; processArray(arIntInp); 2. Create an array on the fly and pass it processArray(new int[]{0,9});
How do you pass a 2D array in a functions?
if you were to call a function you would write it as: function(array[][], int pretend, double pretend2); arrays will always be passed by reference, not by value.
How you pass array elements to a function Give an example?
You can pass array elements just as you would pass a named variable. void f(int& x) {/*...*/} int main() { int a[] {4,8,15,16,23,42}; f (a[3]); // pass the 4th element to f... }
How do you pass an array as a parameter?
AnswerUnfortunately your question is to broad. All progamming languages vary in the way things are done. I will just give a general way of doing it.You have to pass the multidimensional array into the function by including it with calling the function. On the receiving end you have to declare another multidimensional array so the information can be passed into it. Depending on the language, you may not be passing in a multidimensional array, instead that array may be stored in an object which you can pass instead.Hope this helps some.-Ashat-in C, when passing two dimensional arrays the compiler needs to know the width so it can calculate memory offsets.passing a 2d array of width 4:voidFunc(type array[][4]);
How do you pass a one-dimensional array to user-defined functions?
In C++ you would pass a std::array if the array is fixed-length, otherwise you'd use a std::vector. Most object oriented languages will provide some method of passing a self-contained array object to a function. In C and other non-object oriented languages you would pass a reference or pointer to the start address of the array along with a variable indicating the number of valid elements within the array. The array type will determine the size of each element.
Why it is not possible to pass a function as an argument to another function in c?
It is quite possible. A well-known example is the fourth parameter of qsort.
How do you pass a variable by value in php?
In the declaration of the receiving function, you add an ampersand. <?php function myWayCoolFunction( &$params) {.....} $x = array('1','2','3'); myWayCoolFunction($x) ?>
When does an array behave like a pointer in C plus plus -- provide sample code to support each case?
An array never behaves like a pointer.Understand that a pointer is a variable -- no different to any other variable, other than its type. like any other variable, it is allocated its own memory (4 bytes in a 32-bit system). Those 4 bytes can store any 32-bit value, from 0x00000000 to 0xFFFFFFFF, but because it is declared to be a pointer, that value actually represents a memory location, somewhere within the 4GB address space. 0x00000000 is a reserved memory location -- what we refer to as NULL.An array is not the same as a pointer in any sense. The array name refers to the actual memory (the starting address) where the array resides. But the array name is not a variable -- unlike a pointer, it is not separate from the memory it refers to -- it is merely an alias that refers to the memory allocated to the array itself.That said, pointers and arrays can appear to be the same. For instance, the strlen() function expects you to pass a const char pointer, and yet you can pass an array name instead and it works just fine:char cArray[12];char * p = cArray;strlen( p ); // Pass a pointerstrlen( &cArray[0] ); // Pass pointer to array element via AddressOf operatorstrlen( cArray ); // Pass an array nameAll three of these functions work exactly the same so it would be easy to assume the array is a type of pointer. But it is not. To understand what's really going on here you have to understand how pointers and arrays are actually passed to function.When you pass a pointer to a function, you don't pass the pointer itself, you pass the memory address stored in the memory allocated to the pointer. In other words, pointers are passed by value, not by reference. Similarly, when you pass an array name, you pass the starting address of the array.That's all there is to it! The function's parameter, a pointer, is allocated its own memory. It is a temporary variable, local to the function. All it expects is a memory location so whether you pass a pointer or an array name, that's exactly what it receives.
