Operators

For example, let's have a look at the following code - I have included the evolution of the content stored in the variables as comments:

// assignment operator
#include <iostream>
using namespace std;
int main ()
{
  int a, b;         // a:?,  b:?
  a = 10;           // a:10, b:?
  b = 4;            // a:10, b:4
  a = b;            // a:4,  b:4
  b = 7;            // a:4,  b:7

  cout << "a:";
  cout << a;
  cout << " b:";
  cout << b;
} 

Output:a:4 b:7
