Initialization of Arrays Using Functions 519

12.9 Program to pass entire elements of an array to a function.

#include<iostream.h>

#include<conio.h>

void show(int *,int);

void main()

{

int num[5]={1,2,3,4,5},i;

clrscr();

cout<<“\nElements of the array are as follows:”;

show(&num[0],5);

}

void show(int *x,int y)

{

int i;

for(i=0;i<=y-1;i++)

{

cout<<“ ”<<*x;

x++;

}

}

OUTPUT

Elements of the array are as follows: 1 2 3 4 5

Explanation: In the above program, the address of the zeroth element, that is, &num[0], is

passed to the function show(). The for loop is used to access the array elements using point-

ers. The show() function is invoked with
