Write a routine to interchange the mth and nth elements of a singly-linked list. You may assume that the ranks m and n are passe
IRINA_888 [86]

Answer:

//The routine to swap m th and nth ranked elements

void swapmAndn(int m, int n)

{

  //Set the linked list head node

  Linked_Node **node_head

  //To find the m ranked node

  //set previous node  

  Linked_Node *node_prev = NULL;

 

  //set node to store m ranked node as head node

  Linked_Node *node_current_m = *node_head;

 

  //set the rank as rm=1

  rm =1

  //traverse to find the m ranked node

  while (node_current_m && rm<m)

  {    

      node_prev = node_current_m;

      node_current_m = node_current_m->next;

      rm++;

  }

 

  //To find the n ranked node

  //set previous node  

  Linked_Node *node_prev_n = NULL;

 

  //set node to store n ranked node as head node

  Linked_Node *node_current_n = *node_head;

 

  //set the rank as rn=1

  rn =1

  //traverse to find the n ranked node

  while (node_current_n && rn<n)

  {    

      node_prev_n= node_current_n;

      node_current_n = node_current_n->next;

      rn++;

  }

 

  //if m is not first ranked node

  if (node_prev != NULL)

      //set node_current_n as previous node

      node_prev->next = node_current_n;

 

  //otherwise Set the node_current_n

  else

      *node_head = node_current_n;

 

  // If n is not first ranked node

  if (node_prev_n!= NULL)

      node_prev_n->next = node_current_m;

  else

      *node_head = node_current_m;

 

  //now swap the next pointers also

  //to make the swap process complete  

  Linked_Node *temp = node_current_n->next;

  node_current_n->next = node_current_m->next;

  node_current_m->next = temp;

}

the 4gl languages that enable nonprogrammers to use certain easily understood commands to search and generate reports from a dat
Mademuasel [1]

The 4gl languages that enable non-programmers to use certain easily understood commands to search and generate reports from a database are called <u>query</u>.

<h3>What is 4gl?</h3>

A computer programming language that is part of a class that is intended to improve upon third-generation programming languages (3GL) is known as a fourth-generation programming language (or 4GL).

Every generation of programming language strives to provide a greater level of abstraction of the internal workings of the computer hardware, making the language more user-friendly, potent, and adaptable.

Despite the fact that the definition of 4GL has evolved over time, it can still be characterized by the fact that it works more with large groups of data at once rather than concentrating on just bits and bytes.

The support for report generation, database management, mathematical optimization, GUI development, and web development may be found in languages that advertise themselves as 4GL. According to some academics, domain-specific languages include 4GLs as a subset.
