RFID stands for Radio-Frequency Identification. RFID is the use of radio waves to reach and capture data. The RFID chip can hold about 2,000 bytes of info.
The RFID device serves the same purpose as a bar code or a magnetic strip on the back of a credit card or ATM card; it provides a unique identifier for that object. And, just as a bar code or magnetic strip must be scanned to get the information, the RFID device must be scanned to retrieve the identifying information.

Bonjour ma question est: expliquer comment fonctionne une calculatrice qui ne contient pas une pile. Pouvez-vous m'aider?

larisa [96]

Answer:

Tout calculateur électronique ou numérique nécessite une source d'alimentation pour fonctionner, avec son circuit configuré à la porte logique requise liée aux touches d'entrée et à l'écran de sortie.

Explanation:

Les calculatrices sont des appareils utilisés pour les calculs arithmétiques. Au 19ème siècle, les calculatrices étaient mécaniques et n'utilisaient pas de batterie, elles étaient encombrantes et utilisaient des tiges et des engrenages dans leur fonctionnement. Les calculatrices récentes sont électroniques, alimentées par une batterie. Ils comprennent un circuit électronique configuré à sa porte logique requise pour le calcul, un bouton pour l'entrée et un écran pour la sortie du calcul.

Write a c program that reprints input so that no line is longer than 50 characters. Specifically, for lines less than or equal t

Alex73 [517]

Using the knowledge in computational language in C++ it is possible to write a code that reprints prints input so that no line is longer than 50 characters.

<h3>Writting the code:</h3>

#include<stdio.h>

int main(int argc, char** argv){

//creating pointer to read a file

FILE * fp;

char * line = NULL;

size_t len = 0;

ssize_t read;

int i=0;

//opening a file

fp = fopen(argv[1], "r");

//handling the error condition

if (fp == NULL){

printf("File not found..!!");

return 0;

}

int moreThan50 =0;

//reading a file line by line

while ((read = getline(&line, &len, fp)) != -1) {

i = 0;

if(read >= 50){

moreThan50++;

}

while(i < read){

if(line[i]!='\n'){

if(i%50 == 0){

printf("\n%c",line[i]);

}else{

printf("%c",line[i]);

}

i++;

}

printf("\nTotal lines over 50 chars: %d\n",moreThan50);

printf("Offending Lines: ");

for(i=1;i<=moreThan50;i++)

printf("%d, ",i);

fclose(fp);

return 0;

}

Explanation:

Read a number from user using the input function of Python.
Use the format function of Python to correctly format the output according to the given requirements.
Note: Use Python 3.6 or above for this code to run without any issue.

Output:
