Arrays as parameters to functions

(1)Arrays are always passed by reference to functions. So there no need to add the &symbol, which means that if the array is changed in the function, then it is alsochanged in the main.

(2)Functions cant return array.int[ ] copy (int list[ ], int size); invalid

Example:

#include

#includeusing namespace std;

void initialize (int arr[ ], int size);

void Copy(const int A[ ], int B[ ], int size);

int main(){

int list[10]={0}, X[10];

initialize(list, 10);

Copy(list, X, 10);

cout

Examples of Functions processing 1D array

void initializeArray(int list[], int listSize)

{

int index;

for (index = 0; index < listSize; index++)list[index] = 0;

}

void fillArray(int list[], int listSize){

int index;

for (index = 0; index < listSize; index++)

cin >> list[index];}

void printArray(const int list[], int listSize)

{

int index;

for (index = 0; index < listSize; index++)

cout

Exercise:

Write a function named duplicate that takes an array of int, and the array size. The

function should check if the array has any duplicates and output an appropriate

message.

#include using namespace std;

void duplicate (int list[ ], int size);int main()

{

int list[10]={1,9,3,4,5,6,7,8,9,10};

duplicate(list, 10);system("pause");

return 0; }

void duplicate (int list[ ], int size)

{

int i,j; bool found=false;for(i = 0; i
