Given the following function:
void calc (int a, int& b)
{
$\quad$Int c;
$\quad$c = a + 2;
$\quad$a = a * 3;
$\quad$b = c + a;
}
What is the output of the following code segment that invokes calc():
Int x = 1;
Int y = 2;
Int z = 3;
Calc(x, y);
Cout

E) 2 3 4 5

Quizplus · Accepted Answer

When the function calc() is called with arguments (x, y), the following happens: 
1. Variable "c" is assigned the value of "a+2", which is 1+2 = 3.
2. Variable "a" is assigned the value of "a*3", which is 1*3 = 3.
3. Variable "b" is assigned the value of "c+a", which is 3+3 = 6.
Therefore, after the function call, the values of x and y are updated to 3 and 6 respectively. The value of z remains unchanged at 3. 
Thus the output of the code segment is "1 6 3".
