Transport layer:

In the OSI model, this layer lies on the 4th part, which primary function is to directly supply the network connectivity to applications mostly on various hosts.

It provides end-to-end communication over a network and also allows you to send and receive error-free data in the form of data packets that enhanced your privacy.

Flow control and Error control:

The flow control is only used to send or receive information transmission only, while Error control is used designed for error-free communication for both (sender or receiver).

Layer related to the data link layer:

It must be done at different layers on both layers like node-to-node connections, the communicative needs are controlled by flow and error. Flow and error control in the transport layer is done from endpoint to endpoint.

Answers

Answer:

nums=[14, 36, 31, -2, 11, -6]

print(nums)

Explanation:

I got a 100%

Answer:

In C++:

#include <iostream>

using namespace std;

int main(){

    int nums[6] = {14, 36, 31, -2, 11, -6};

    cout<<"[";

    for(int i = 0;i<6;i++){

    cout<<nums[i];

    if(i != 5){cout<<", ";}

    }

    cout<<"]";

   return 0;

}

Explanation:

This initializes the array

    int nums[6] = {14, 36, 31, -2, 11, -6};

This prints the opening square bracket

    cout<<"[";

This iterates through the array

    for(int i = 0;i<6;i++){

This prints individual elements of the array

    cout<<nums[i];

Until the last index, this line prints comma after individual array elements

    if(i != 5){cout<<", ";}

    }

This prints the closing square bracket

    cout<<"]";
