[C++ Primer] Passing an array to a function by reference/pointers

#include<cstdlib>

#include<iostream>



usingnamespacestd;



//Takes a pointer to the array, and the size of the array.

voidprint_arr1(constintarr, size_t size)

{

for(size_t ix=0; ix!=size;++ix) {

cout<<arr[ix]<<'';

}

cout<<endl;

}



//Takes 2 pointers. One to the beginning of the array,

//and one to 1 past the last element - just like iterating through a vector.

voidprint_arr2(constintbeg,constintend)

{

for(/empty/; beg!=end;++beg) {

cout<<beg<<'';

}



cout<<endl;

}



//Takes an array of size 10 and uses it as a const reference.

voidprint_arr3(constint(&arr)[10])

{

size_t size=10;

for(size_t ix=0; ix!=size;++ix) {

cout<<arr[ix]<<'';

}

cout<<endl;

}



intmain()

{

intarr[]={0,1,2,3,4,5,6,7,8,9};

int*parr=arr;



print_arr1(parr,10);

print_arr2(parr, parr+10);

print_arr3(arr);



returnEXIT_SUCCESS;
