What will be the output of the following C++ code?

#include <iostream>
using namespace std;
void Sum(int a, int b, int & c)
{
    a = b + c;
    b = a + c;
    c = a + b;
}
int main()
{
    int x = 2, y =3;
    Sum(x, y, y);
    cout << x << " " << y;
    return 0; 
}

A. returnType functionName(parameters) { body; } B. functionName(parameters) { returnType body; } C. functionName(returnType, parameters) { body; } D. returnType functionName(parameters, body) { }

A. Determines the parameters of the function B. Specifies the return type of the function C. Provides the implementation of the function D. Declares the function before it is defined

A. return B. null C. void D. None of the above

A. add(a, b); B. add(int a, int b); C. functionName = add(a, b); D. add.functionName(a, b);
