Can you answer this question?
patriot [66]

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;

}

Unlike radio frequency identification (RFID) tags, bar codes: Question 30 options: require a reader that tunes into a specific f
iris [78.8K]

Answer:

require direct line-of-sight scanning.

Explanation:

Unlike radio frequency identification (RFID) tags, bar codes require direct line-of-sight scanning. Meaning you need a device that can scan the bar code and the scanner needs to be directly pointing at the barcode without anything in the way. This is because bar codes work by embedding the information in a design of lines that need to be scanned to retrieve the information. If anything gets in the way it interrupts the scanning process and the data is not correctly transmitted. RFID tags on the other hand do not need a direct line of sight since the information is transferred through radiofrequency. This allows the data to be transferred without a line of sight and at a distance of up to 300ft.
