Calling a function by passing the address of an actual argument is called, call by address.

Program

#include<iostream>
using namespace std;
void swap(int *a, int *b){ 
int z; z = *a; *a = *b; *b = z; } 
int main(){ 
int a = 31, b = 32;
cout<<"Before :"<<a<<","<<b<<endl;
swap(&a,&b);
cout<<"After :"<<a<<","<<b; return 0;
}

Output:-Before :31,32
After :32,31

Explanation of the program

Here, the address of the arguments is passed into the function and not the value of the variables.
