Answer:
To do this you'll need to use malloc to assign memory to the pointers used. You'll also need to use free to unassign that memory at the end of the program using the free. Both of these are in stdlib.h.
#include <stdlib.h>
#include <stdio.h>
#define SIZE_X 3
#define SIZE_Y 4
int main(void){
int **matrix, i, j;
// allocate the memory
matrix = (int**)malloc(SIZE_X * sizeof(int*));
for(i = 0; i < SIZE_X; i++){
matrix[i] = (int *)malloc(SIZE_Y * sizeof(int));
}
// assign the values
for(i = 0; i < SIZE_X; i++){
for(j = 0; j < SIZE_Y; j++){
matrix[i][j] = SIZE_Y * i + j + 1;
}
}
// print it out
for(i = 0; i < SIZE_X; i++){
for(j = 0; j < SIZE_X; j++){
printf("%d, %d: %d\n", i, j, matrix[i][j]);
}
}
// free the memory
for(i = 0; i < SIZE_X; i++){
free(matrix[i]);
}
free(matrix);
return 0;
}
Different types of connections are..
-A network is two or more devices connected through links.
-There are two possible types of connections: point-to-point and multipoint.
-A point-to-point connection provides a dedicated link between two devices.
Explain the different types of topologies
-Star network…
In star topology each device in the network is connected to a central device called hub. Unlike Mesh topology, star topology doesn't allow direct communication.
-Ring network…
A number of repeaters are used for Ring topology with large number of nodes, because if someone wants to send some data to the last node in the ring topology
-Bus network…
In bus topology there is a main cable and all the devices are connected to this main cable through drop lines. There is a device called tap that connects the drop
-tree topology…
Tree topologies have a root node, and all other nodes are connected which form a hierarchy. So it is also known as hierarchical topology. This topology integrates

Different type of networks
-Computer network…
Virtual Private Network (VPN). By extending a private network across the Internet, a VPN lets its users send and receive data.
-LAN…
Using routers, LANs can connect to wide area networks (WANs, explained below) to rapidly and safely transfer data. 3. Wireless Local Area Network (WLAN).
-Wide area network…
Wide area network, or WAN. In terms of purpose, many networks can be considered general purpose, which means they are used for everything from sending files etc.
-Metropolitan area network…
MAN or Metropolitan area Network covers a larger area than that of a LAN and smaller area as compared to WAN. It connects two or more computers that are apart.
-Wireless LAN…
WLAN (Wireless Local Area Network) helps you to link single or multiple devices using wireless communication within a limited area like home, school, or office
-Wireless network…
A Wireless Local Area Network or WLAN is a network that is used to connect different devices without using wires etc.
-Storage area network…
Storage Area Network is a type of network which allows consolidated, block-level data storage. It is mainly used to make storage last longer etc.
-Personal area network…
PAN can be used for establishing communication among these personal devices for connecting to a digital network and the internet.
-Campus area network…
A Metropolitan Area Network or MAN is consisting of a computer network across an entire city, college campus, or a small region. This type of network is large.
Explain your own understand about protocol and standards
A protocol defines a set of rules used by two or more parties to interact between themselves. A standard is a formalized protocol accepted by most of the parties that implement it.
explain layers in OSI model
Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Explain layers in tcp/ip model
Four layers of TCP/IP model are 1) Application Layer 2) Transport Layer 3) Internet Layer 4) Network Interface. ... It is also known as a network layer. Transport layer builds on the network layer in order to provide data transport from a process on a source system machine to a process on a destination system.
what are the peer to peer processing
In peer-to-peer (P2P) networking, a group of computers are linked together with equal permissions and responsibilities for processing data. Unlike traditional client-server networking, no devices in a P2P network are designated solely to serve or to receive data
Hi,
The word you are looking for is "Hacking".
"Hacking is unauthorized entry into a computer system via any means."
Hope this helps.

No, it is not necessary that variables that contain numbers should always be declared as integer or floating-point data types.
It is not necessary that variables that contain numbers should be declared as integer and floating point data types. Because number can be declared with different data types. As we know that data type is a vital aspect in programming. It describes the type of a value that is contained in a variable. It is the data type based on which memory is allocated to a number or any type of variables.
Numbers can be whole decimal/fractional, signed, unsigned, small, and long. Simply, they exist in a variety of values. According to their values range, the amount of memory is reserved.
Different programming languages offer different data types to store numbers, depending on their types and size. Let’s consider some examples of data types used in programming languages in order to declare variables holding numbers.
- In Python int, float, and complex are the data types used to declare number type variables.
- SQL uses INTEGER, SMALLINT , BIGINT , NUMERIC() , and DECIMAL() data types for numbers.
- To deal with number type variables, Java has six predefined data types, such as int, long, short, byte, float, and double.
- JavaScript uses a single data type called 'number' to declare numbers.
- In C++, two fundamental data types, int and float, are used to represent numeric variables. But C++ is not only limited to these two data types. The data type char can also store numbers. Other data types for declaring numbers as variables are derived from int, float and char, such as short int, long int, signed int, unsigned int, double, long double, signed char, unsigned char etc. etc.
So in concluding remarks, declaring a number type variable is not only limited to using integers and floating-points data types. Rather it entirely depends on the respective programming language, and size and type of the number to be stored in the variable.
