How does this work? ( functionName(bool& hi) )

(Toggle Plain Text)

#include 
using namespace std;

void someFunction(bool& a);

int main()
{
 bool a = true;

 someFunction(a);

 if( a )
 cout <<"a = true";

 else
 cout <<"a = false";
}

void someFunction(bool& a)
{
 a = false;
}

#include<br /><br />using namespace std;</p><br /><p>void someFunction(bool& a);</p><br /><p>int main()<br /><br />{<br /><br /> bool a = true;</p><br /><p> someFunction(a);</p><br /><p> if( a )<br /><br /> cout

This will print out "a = false".

bool& a in the someFunction contains a memory address, no?

So how can you take a memory address = value?

Wouldn't that try to change the memory address into false in this case?
