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;
}
Answer:
True
Explanation:
WLANs and WANs uses wireless networking to communicate within end devices in a network. Cable networks are restricted to only a fixed area or location like a building but wireless networking surpasses that problem of immobility. With a wireless network, users can connect and work with their own personal devices and can be in any location within the premises.
Wireless network is revolutionary, but it's disadvantages are quite problematic. An increasing wireless cluster can impede network allow. As a device is added to a network, it takes a bandwidth and a more is being add, more bandwidth are taken, choking the media.
A user has to be close to the AP for better transmission and wireless is susceptible to attackers.
#include <iostream>
#include <string>
using namespace std;
int main() {
string userInput;
cout << "Enter word" << endl;
cin >> userInput;
cout << "you entered" << endl;
cout << userInput;
return 0;
}
