The following program should reverse each line the user types. Fix it.
Note: the hard-looking stuff is all correct. The problem is much simpler. Trust the error message.
#include
#include
char *reverse(char *s) {
int len=strlen(s);
char buf[256];
char *b=buf;
for(char *e=s+len-1;e>=s;e--,b++) {
*b=*e;
}
*b='\0';
return buf;
}
int main(void) {
char s[256];
while(fgets(s,256,stdin)) {
s[strlen(s)-1] = '\0'; // eliminates the trailing \n
printf("%s\n",reverse(s));
}
}
(c++)

Answers

Answer 1

Here's the corrected version of the program:

```cpp

#include <iostream>

#include <cstring>

char* reverse(char* s) {

   int len = std::strlen(s);

   char* buf = new char[len + 1];

   char* b = buf;

   

   for (char* e = s + len - 1; e >= s; e--, b++) {

       *b = *e;

   }

   *b = '\0';

   

   return buf;

}

int main() {

   char s[256];

   

   while (std::cin.getline(s, 256)) {

       std::cout << reverse(s) << std::endl;

   }

   

   return 0;

}

```

In the corrected version, I made the following changes:

- Added necessary headers `<iostream>` and `<cstring>` for input/output and string functions.

- Changed `printf` and `fgets` to `std::cout` and `std::cin.getline` for C++ style input/output.

- Replaced the use of `strlen` in the `reverse` function with `std::strlen`.

- Allocated memory for the `buf` array dynamically using `new[]` to avoid using a local array that would go out of scope.

- Properly terminated the `buf` array with a null character `'\0'` after reversing the string.

These changes should fix the program and allow it to reverse each line that the user types.

Para que se utilizan las siguientes plataformas: Matlab, Labview, VisualBasic, Mplab, Micropic, PicCompiller

Answers

Answer:

MATLAB (abreviatura de MATrix LABoratory, «laboratorio de matrices») es un sistema de cómputo numérico que ofrece un entorno de desarrollo integrado (IDE) con un lenguaje de programación propio (lenguaje M). Está disponible para las plataformas Unix, Windows, macOS y GNU/Linux.

Entre sus prestaciones básicas se hallan la manipulación de matrices, la representación de datos y funciones, la implementación de algoritmos, la creación de interfaces de usuario (GUI) y la comunicación con programas en otros lenguajes y con otros dispositivos hardware.

LABVIEW (acrónimo de Laboratory Virtual Instrument Engineering Workbench) es una plataforma y entorno de desarrollo para diseñar sistemas, con un lenguaje de programación visual gráfico pensado para sistemas hardware y software de pruebas, control y diseño, simulado o real y embebido.

Visual Basic (VB) es un lenguaje de programación dirigido por eventos, desarrollado por Alan Cooper para Microsoft. Este lenguaje de programación es un dialecto de BASIC, con importantes agregados. Su primera versión fue presentada en 1991, con la intención de simplificar la programación utilizando un ambiente de desarrollo.

MPLAB es un editor IDE gratuito, destinado a productos de la marca Microchip. Este editor es modular, permite seleccionar los distintos microcontroladores soportados, además de permitir la grabación de estos circuitos integrados directamente al programador.

MICROPICUn PIC es un circuito integrado programable (Programmable Integrated Circuited), el cual contiene todos los componentes para poder realizar y controlar una tarea, por lo que se denomina como un microcontrolador. Los PIC son una familia de microcontroladores tipo RISC fabricados por Microchip Technology Inc. y derivados del PIC1650, originalmente desarrollado por la división de microelectrónica de General Instrument.

PLS HELP ASAP suppose you want to find pages that contain the word German but not the word shepherd. which search would achieve this?

Answers

Answer: German- shepherd

Explanation:

If I want to find pages that contain the word German but not the word shepherd, the search would achieve this would be German- shepherd.

It should be noted that other options such as German OR shepherd, "GERMAN shepherd" and "German"+"shepherd" all mean that pages containing the words German and also shepherd will be found.

The (-) sign simply means that not. Therefore, the correct option is German - shepherd which means German but not shepherd.

I need help writing the algorithm I know how to do the flow chart for the first one but I’m not sure if the second question is a for loop

Answers

Answer:

The algorithm is as follows:

(a) Sales and commission

1. Start

2. Input Sales

3. Commission = 0.30 * Sales

3. If sales >= 4000.00 then

3.1   Commission = 0.60 * Sales

4. End If

5. Print Commission

6. Stop

(b) Amount of Rainfall

1. Start

2. Days = 1

3. Total = 0.0

4. While Days <= 31

4.1. Input Rainfall

4.2. Total = Total + Rainfall

4.3. Days = Days + 1

4.4. End If

5. Print Total

6. Stop

See attachment for flowchart

Explanation:

(a) Sales and commission

This begins the algorithm

1. Start

This gets sales from the user

2. Input Sales

This calculates the commission based on 30% (i.e. for sales < 4000)

3. Commission = 0.30 * Sales

This checks if sales is greater than or equal to 4000

3. If sales >= 4000.00 then

This calculates the commission as 60% of Sales

3.1   Commission = 0.60 * Sales

This ends the if condition

4. End If

This prints the calculated commission

5. Print Commission

This ends the algorithm

6. Stop

(b) Amount of Rainfall

This begins the algorithm

1. Start

This initializes the number of days to 1

2. Days = 1

This initializes total rainfall to 0

3. Total = 0.0

The following while loop is repeated until day 31st

4. While Days <= 31

This gets input for Rainfall from the user

4.1. Input Rainfall

This calculates the total rainfall

4.2. Total = Total + Rainfall

This increments the number of days

4.3. Days = Days + 1

This ends the if statement

4.4. End If

This prints the total rainfall

5. Print Total

This ends the algorithm

6. Stop

Answer:

. ¿Dónde emergieron los Bancos Centrales?

El primer banco central fue creado por el Parlamento Sueco en 1668, siendo su principal acreedor la Corona Sueca. Esto generó inflación y crisis financieras. Después de un siglo, en 1779, la ley fue modificada, obligando al Banco a que la masa monetaria fuese respaldada por oro en una proporción fija. Sin embargo, comenzó la guerra con Rusia y se regresó a su origen violando el precepto de estabilidad que confería ese patrón oro.

2. ¿En qué siglo los Bancos Centrales se potenciaron?

La historia de la banca central se remonta al menos al siglo XVII, con la fundación de la primera institución reconocida como un banco central, el Banco de Suecia.

3. ¿El Banco de Suecia en qué siglo fue fundado?

El primer banco central fue creado por el Parlamento Sueco en 1668.

Fue creado por Napoleón en 1800 para estabilizar la moneda después de la hiperinflación del papel moneda generado durante la Revolución Francesa y las conquistas napoleónicas.

A company that is operating a factory or assembly line may experiment with different methods of arranging the assembly line or with different production methods. Each time the production process is changed, this is a different iteration. Each time the order of operations and procedures are changed, this is a different iteration. The goal is to achieve the fastest, best and most optimal method of creating a product.

A musician may start with one version of a song and refine it, making changes to a note here and there or changing the tempo and speed. Many different iterations of a song may be created this way until the optimal finished product has been created that sounds and works the best.

A cook may experiment with a recipe, tweaking the ingredients or changing different steps of the process slightly until the food tastes as good as it possibly can.
