Pass an Array by Reference in C++

If we pass the address of an array while calling a function, then this is called function call by reference. The function declaration should have a pointer as a parameter to receive the passed address, when we pass an address as an argument.

Example Code

 Live Demo

#include <iostream> using namespace std; void show( int *num) {    cout<<*num; } int main() {    int a[] = {3,2,1,6,7,4,5,0,10,8};    for (int i=0; i<10; i++) {       show (&a[i]);    } return 0; }
