Answer to Question #339858 in C++ for dave

Question

What is the output of each of the following statements? Assume that

x = 5, y = 2, z = 10, and temp = 0

 

 

1. if (y >= x)

      y = z;

   cout<< x << " " << y << " " << z << endl;

 

2. if (y >= x)

   {

      y = z;

      cout<< x << " " << y << " " << z << endl;

   }

 

3. if (z < y)

      temp = x;

      x = z;

   z = temp;

   cout<< x << " " << y << " " << z << endl;

 

 

4. if (z > y)

   {

      temp = x;

      x = z;

      z = temp;

   }

   cout<< x << " " << y << " " << z << endl;

 

5. if (x >= 6)

   cout<< x + y << endl;

   cout<< x + y << endl;

 

 

 

6. if (x + y > z)

      x = y + z;

   else

      x = y - z;

   cout<< x << " " << y << " " << z << endl;
