I have this code in C that has to calculate a factorial of a number entered by keyboard, once the factorial has been calculated, the option to start the program again to calculate another factorial is shown.

#include <stdio.h>
int main() {
    
    int num,c,rep,factorial;
    
    printf("Introduzca el numero del que desea calcular el factorial: \n");
    scanf("%d",&num);
    c=num;
    
    do{
        factorial=factorial*c;
        c--;
    }while(c=1);
    
    printf("El factorial de %d es %d \n",num,factorial);

    printf("Si desea volver a iniciar el programa pulse 1 si no, pulse cualquier otro numero\n");
    scanf("%d",&rep);
    if(rep==1){
        main();
    }
    else{
        printf("Fin del programa\n");
    }
    
    return 0;
}

My problem is that the program does not calculate the factorial, an infinite loop is generated in do whileit and I know what the problem is. Thank you very much.

I am making a script that you put two numbers and it tells you if they are divisible. But it gives me an error. I am making a script that you put two numbers and it tells you if they are divisible. But it gives me an error. THE SCRIPT CODE:

#!/bin/bash



read -p "Numero 1: " num1

read -p "Numero 2: " num2

cero=0

$op=$(($num1%$num2))

if [$op -eq $cero] 

then

echo "ES DIVISIBLE"

else

echo "NO ES DIVISIBLE"

fi

/divisibles.sh

Numero 1: 4

Numero 2: 4

./divisibles.sh: línea 6: =0: orden no encontrada

./divisibles.sh: línea 7: [: falta un `]'

NO ES DIVISIBLE

I have a lambda that calls putItem to insert a record into a DynamoDB database table.

I get the following access error when executing it:

AccessDeniedException: User: **** is not authorized to perform: dynamodb:PutItem on resource: arn:aws:dynamodb:***:table/*** because no identity-based policy allows the dynamodb:PutItem action

I need to assign a policy to my lambda, exactly one that can perform the putItem function in DynamoBD. I do not know how to do it.

This is my lambda code:

export class NewPlatformIoTCoreStack extends cdk.Stack {
    constructor(scope: Construct, id: string, props?: cdk.StackProps) {
      super(scope, id, props);

      // Rule of IoT Core for MQTT sending of the devices
      
      const constructProps: IotToLambdaProps = {
        lambdaFunctionProps: {
          code: lambda.Code.fromAsset(path.join(__dirname, '../lambdasCode/mqttBroker/')),
          runtime: lambda.Runtime.NODEJS_16_X,
          handler: 'index.handler'
        },
        iotTopicRuleProps: {
          topicRulePayload: {
            ruleDisabled: false,
            description: "Processing of MQTT messages from AWS IoT Stack",
            sql: "SELECT *, topic(4) as device_id FROM 'v1/data/1'",
            actions: []
          }
        }
      };
     
    new IotToLambda(this, 'iot-lambda-integration', constructProps);
      
  };  
}

I have an http call from a backend service that works correctly, this backend service also returns a ResponseEntity<String>(HttpStatus.OK)or against a ResponseEntity<String>(HttpStatus.NOT_FOUND), but I would like to print the response status in the console, can you tell me the correct syntax? I paste my code: Service:

  borrarInforme(): Observable<HttpResponse<string>> {
    return this.httpClient.post<any>(`${this.baseURL + '/borrarInforme'}`, '').pipe(
      catchError(this.handleError)
    );
  }

    guardarInforme(): Observable<HttpResponse<string>> {
    console.log("entro en el metodo para guardar informe");
    return this.httpClient.post<any>(`${this.baseURL + '/guardarInforme'}`, '').pipe(
      catchError(this.handleError)
    );
  }

  handleError(error: HttpErrorResponse) {
    alert('Ha ocurrido un error abre inspeccion para comprobarlo')
    if (error.status === 0) {
      console.error(`Ha ocurrido un error: ${error.error}`)
    } else {
      console.error(`error en el backend ${error.status}. el error de la respuesta es: ${error.error}`);
    }
    return throwError(
      () => 'Algo no ha salido bien'
    );
  }

Next, the component that subscribes to the response of the call, as you can see, I have tried to indicate the type of the response but it tells me that it is null (response prints null) so I understand that the problem is in the service not being correctly structured the method:

  confirmarOk() {
    this.servicio.guardarInforme().subscribe(
      (response: HttpResponse<string>) => console.log(response.status)
    );
    this.dialogRef.close();
    this.router.navigate(['/home']);
  }
  cancelar() {
    this.servicio.borrarInforme().subscribe(
      response => console.log(response)
    );
    this.dialogRef.close();
  }

Next I paste the controller method:

@PostMapping(/guardarInforme)
public ResponseEntity<String> guardarInforme(){
if(this.servicioReportingApp.guardarPDF()){
return new ResponseEntity<String>(HttpStatus.OK);
}
return new ResponseEntity<String>(HttpStatus.NOT_FOUND);

}
@PostMapping(/borrarInforme)
public ResponseEntity<String> borrarInforme(){
if(this.servicioReportingApp.borrarPDF()){
return new ResponseEntity<String>(HttpStatus.OK);
}
return new ResponseEntity<String>(HttpStatus.NOT_FOUND);

}

I want to calculate the factorial of 10 using a while loop, an if branch, and a break statement.

I manage to get the factorial of 10 with the while loop, but how can I get it using the if and break statement?

let x = 10;
var i = x-1;


while(i > 1){
    x *= i;
    i--;
}
console.log(x);
