#include<iostream>
using namespace std;
int main() {
//declararea variabilelor
int a;
unsigned int b;
float c;
//se citesc de la tastatura valori pentru a, b, c
cin >> a >> b >> c;
//se afiseaza valorile variabilelor a, b, c
cout << "a=" << a << " b=" << b << " c=" << c<<"\n";
//se afiseaza suma
cout <<"a+b+c="<< a + b + c;
}
