Connecting the IP phone to a switch port may have configuration issues; here are some of the common configuration issues encountered by network engineers when connecting an IP phone to a switch port:
1. Voice traffic may not be configured.
2. Data traffic may not be configured.
3. Both voice traffic and data traffic are not configured.
4. Inline power support may have been overlooked.
5. QoS may not be configured properly.
6. QoS may not be configured on<span> the Layer 2 Uplink.
7. QoS may not be configured </span><span>on the Layer 3 Uplink.
8. This is the most common issue encountered; all issues above may have been met but if this one is not addressed, the switch will not respond properly: Cisco predefined macro is not used to configure the switch.</span>
Answer:
#include <iostream>
using namespace std;
class ProblemSolution {
private:
int num1, num2;
public:
ProblemSolution(int n1, int n2) {
num1 = n1;
num2 = n2;
}
int calculateSum() {
int sum = 0;
sum = num1 + num2;
return sum;
}
void printSum() {
// calculateSum will return sum value that will be printed here
cout <<"Sum = "<< calculateSum();
}
~ProblemSolution() {
cout << "\nDestructor is called " << endl;
};
};
int main() {
int a, b;
cout << "Enter a: ";
cin >> a;
cout << "Enter b: ";
cin >> b;
// Initiallizing object pointer of type ProblemSolution
ProblemSolution *objPtr = new ProblemSolution(a,b);
// printing Sum
objPtr->printSum();
// delete objPtr to relaease heap memory :important
delete objPtr;
return 0;
}
Explanation:
we will initialize a pointer "objPtr" and initallize the constructor by passing 2 values a and b followed by the keyword "new". the keyword "new" allocates memory in the heap. we can access class member functions using arrow "->". it is important to delete objPtr at the end of the program so that the heap memory can be freed to avoid memory leakage problems.
Answer:
input device
Explanation:
any hardware device that allows users to enter programs, data, and commands into a computer system
Probably not
Not a good idea my friend
Answer:
Procedural programming is also referred to as imperative programming. Procedural programming languages are also known as top-down languages.
