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
Answer:
False
Explanation:
Access Control Lists (ACLs) are network filters used by routers and some switches to permit and restrict data flows in and out of network devices. When an ACL is implemented in a device or interface, the network device analyses data passing through it, compares it to the specification described in the ACL, and allows it the data to flow or prohibits it. One of the main reasons ACLs arre used is to provide a basic level of security for networks. If anything, the use of ACLs and their complexities bring about a delay in transmission through networks.
A already assigned variable cannot be assigned twice You can make the variable change over to a new one or call a whole new one to assign one without a value or It might be possible to do v=n (v is variable and n is number / value)
Answer:
I don't know the language this is but here is something that will work for all lang
int num0 = 0;
int num1 = 0;
basically just print the ints in the right dimension

Sorry if I am wrong
I don't know much about this someone else's answer might be better than mine
