To pass an entire array to a function, only the name of the array is passed as an argument. result = calculateSum(num); However, notice the use of [] in the function definition. This informs the compiler that you are passing a one-dimensional array to the function.

Can we send an array as a parameter to a function?

C++ does not allow to pass an entire array as an argument to a function. However, You can pass a pointer to an array by specifying the array’s name without an index.

How do you pass a character array to a function in Java?

Passing Arrays to Methods in Java

1. Just as you can pass primitive type values to methods, you can also pass arrays to a method.
2. Then the method call will look like, modify (num);
3. As array reference is passed to the method so the corresponding parameter in the called method header must be of array type.

When you pass an array name as an argument to a function what gets passed?

1) In C, if we pass an array as an argument to a function, what actually get passed? The correct option is (b). Explanation: In C language when we pass an array as a function argument, then the Base address of the array will be passed.

How do you take an array as a parameter in Java?

To pass an array as an argument to a method, you just have to pass the name of the array without square brackets. The method prototype should match to accept the argument of the array type. Given below is the method prototype: void method_name (int [] array);

How do you convert this character array to string?

char[] arr = { ‘p’, ‘q’, ‘r’, ‘s’ }; The method valueOf() will convert the entire array into a string. String str = String. valueOf(arr);

How do you pass an array to a thread in Java?

How do you call an array as a parameter?

How do I sort an array of char pointers?

You need to parse an array of pointers to char to sort (instead of just pointer to char). As jhx pointed out, you need to pass the size of the array as well. You can use sizeof so as to not hard-coding 4. Also omit the array size when initialize it.

How do you return an array from a function?

We can either have an array as a parameter. Or, we can have a pointers in the parameter list, to hold the base address of our array. We will study the second way in details later when we will study pointers. We don’t return an array from functions, rather we return a pointer holding the base address of the array to be returned.
