How to 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
#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;
}Output
