In the main function I created a local variable x . then passed it by reference to fun function . where the function declaration is int fun(int &x);
but I am not understanding how the local variable is passing to fun function.
if it would int &x=x where first x is the formal parameter and second x is the local variable . though the statement int &x=x shows error in a function .but why this is not showing any error or warning here. if anybody could not understand my question. plz give me details on how a reference variable would pass in a function. another thing I want to add is this. if a reference variable would been created in the memory
#include<iostream>
using namespace std;
int fun(int &x)
{
return x;
}
int main()
{
int x=10;
cout << fun(x);
return 0;
}
