Select-WE4-P1

Q11: Click on the statements belonging to the else-branch in the following code

if (alpha < delta)
   gamma = alpha + 5;
else
   gamma = beta + 5;
   eta = beta + 2;

Use this given setup for each of the questions below.

int alpha = 2, beta = 1, delta = 3, eta = 0, gamma = 0;

Q12: After executing the following code, the value in variable gamma is and the value in variable eta is .

if (alpha < delta)
   gamma = alpha + 5;
else
   gamma = beta + 5;
   eta = beta + 2;

Q13: After executing the following code, the value in variable gamma is and the value in variable eta is .

if (alpha > beta)
{
   eta = alpha + 2;
   gamma = alpha + 5;
}
else
{
   eta = alpha - 1;
   gamma = beta - 1;
}
