Answer:
B. 1 6 3
Explanation:
Given function definition for calc:
void calc (int a, int& b)
{
int c;
c = a + 2;
a = a * 3;
b = c + a;
}
Function invocation:
x = 1;
y = 2;
z = 3;
calc(x, y);
cout << x << " " << y << " " << z << endl;
- Since x is passed by value, its value remains 1.
- y is passed by reference to the function calc(x,y);
Tracing the function execution:
c=3
a=3
b=c+a = 6;
But b actually corresponds to y. So y=6 after function call.
- Since z is not involved in function call, its value remain 3.
So output: 1 6 3

I’m positive this is the correct answer
Answer:
The real-time transport protocol (RTP) carries the audio and video data for streaming and uses the real-time control Protocol to analyse the quality of service and synchronisation. The RTP uses the user datagram protocol ( UDP) to transmit media data and has a recommended Voice over IP configuration.
Explanation:
RTP is a network protocol used alongside RTCP to transmit video and audio file over IP networks and to synchronise and maintain its quality of service.
