#include<iostream>
#include<cstdio>
using namespace std; // make the std built-in symbols active, instead of std::cin, std::cout, etc.
void swap(float &x ,float &y)
{
float t=x;
x=y;
y=t;
}
int main() // cpp standard, instead of "void main" in c standard
{
void swap(float &,float &);
float a,b;
cin>>a>>b;
cout<<"a:="<<a<<"b:="<<b<<endl;
swap(a,b);
cout<<"a:="<<a<<"b:="<<b<<endl;
return 0; // must return an int
