Answer: Opened

Explanation:

  • File is defined as object that holds information, commands ,data etc and allotted with specific name known as file name.
  • A file needs to be opened for performing functions like reading, writing changing elements, saving any changes made  or closing etc.
  • Other options are incorrect because buffer is used for holding information before using it for short period of time.
  • Closing action can be performed only after opening a file. Initialization is defining any value that is required in program.
  • Thus , the correct option is opened.

Sav [38]

Answer:

#include <stdio.h>

void interchangeCase(char phrase[],char c){

  for(int i=0;phrase[i]!='\0';i++){

      if(phrase[i]==c){

          if(phrase[i]>='A' && phrase[i]<='Z')

              phrase[i]+=32;

          else

              phrase[i]-=32;      

      }

  }

}

int main(){

  char c1[]="Eevee";

  interchangeCase(c1,'e');

  printf("%s\n",c1);

  char c2[]="Eevee";

  interchangeCase(c2,'E');

  printf("%s\n",c2);    

}

Explanation:

  • Create a function called interchangeCase that takes the phrase and c as parameters.
  • Run a for loop that runs until the end of phrase and check whether the selected character is found or not using an if statement.
  • If the character is upper-case alphabet, change it to lower-case alphabet and otherwise do the vice versa.
  • Inside the main function, test the program and display the results.

miss Akunina [59]

Answer:

See explanation below.

Explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question follows:

Suppose you are among those who believe that the NLRA should be transformed. What arguments support the claim that a complete overhaul is necessary? What alternative models might be considered as a replacement for the NLRA model of exclusive representation?

The explanation of the answers is now provided as follows:

a. What arguments support the claim that a complete overhaul is necessary?

The adversarial nature of labor relations in the United States, which many claim is produced by the National Labor Relations Act's (NLRA)'s very existence, is the fundamental reason for its transformation. In a global economy, supporters of transformation say that adversarialism is undesirable for employees and employers because it makes representation and profit maximization more difficult. The principles of exclusive representation and majority support are specific aspects of the NLRA that promote adversarialism.

The fact that it is compulsory for a union to win the support of a majority of workers, the process of representation results into a tone of a "u versus. them". As a result, both sides try to make the other look bad in the eyes of the employees who will vote.

Based on the above, a  complete overhaul is necessary.

b. What alternative models might be considered as a replacement for the NLRA model of exclusive representation?

Giving nonmajority unions legal protection by requiring employers to negotiate with them is one alternative to replace the NLRA model of exclusive representation. Under this, the contracts would not cover all employees; only those who are union members would be covered.

Another alternative is that work councils could also be used to supplement or replace the certification process. Employee free speech rights, wrongful dismissal procedures, employee participation on business boards of directors, and the right to workplace information are all potential transformation factors that might be taken into consideration.
