Slip 17_1 : 1 Implement a list library (singlylist.h) for a singly linked list. Create a linked list, reverse it and display reversed linked lis

-

 Solution :

Header File : singlylist.h

#include <stdio.h>

#include <stdlib.h>

struct node

{

 int data;

 struct node *next;

};

struct node *f;

void create()

{

 struct node *s;

 int n,i;

 printf("Enter how many nodes");

 scanf("%d",&n);

 f=(struct node *)malloc(sizeof(struct node));

 printf("Enter data");

 scanf("%d",&f->data);

 s=f;

 for(i=1;i<n;i++)

 {

 s->next=(struct node *)malloc(sizeof(struct node));

 s=s->next;

 printf("Enter data");

 scanf("%d",&s->data);

 }

 s->next=NULL;

}

void display()

{

 struct node *s;

 for(s=f;s!=NULL;s=s->next)

 {

 printf("%d ->",s->data);

 }

}

void reverse()

{

 int cnt=0,i;

 struct node *s;

 for(s=f;s!=NULL;s=s->next)

 {

 cnt++;

 }

 while(cnt>0)

 {

 for(i=1,s=f;i<cnt;i++)

 {

 s=s->next;

 }

 printf("%d ->",s->data);

 cnt--;

 }

}



Program File

#include<stdio.h>

#include"singlylist.h"

main()

{

 create();

 display();

 reverse();

}

Slip 22_2: Read the data from file 'cities.txt' containing names of cities and their STD codes. Accept a name of the city from user and use sentinel linear search algorithm to check whether the name is present in the file and output the STD code, otherwise output “city not in the list”. Solution :

 Solution : #include<stdio.h> #include<stdlib.h> #include<string.h> struct city {  char name[20];  int code; }ct[10]; int readFile(struct city a[]) {  int i=0;  FILE *fp;  if((fp=fopen("city.txt","r"))!=NULL)  {  while(!feof(fp))  {  fscanf(fp,"%s%d",&a[i].name,&a[i].code);  i++;  }  }  return i-1; } void sentinelsearch(struct city a[10],int n,int sr) { int i,cnt=0;  a[n]=sr;  while(strcmp(sr,a[i].name)!=0) { i++;  }  if(i<n)  printf("city is found and STD code is %d ",a[i].code);  else  printf("city is not found "); } main() { int n;  char sr[20];  n=readFile(ct);  if(n==-1)  printf("File not found ");  else  {  printf("Enter city name to search");  scanf("%s",sr);  SentinelSearch(ct,n,sr);  } }

Slip10_2, 30_1 : Read the data from the file “employee.txt” and sort on names in alphabetical order (use strcmp) using bubble sort or selection sort

-
 Solution :Using Bubble sort #include<stdio.h> #include<stdlib.h> #include<string.h> struct employee {  char name[20];  int age; }emp[10]; int readfile(struct employee a[10]) {  int i=0;  FILE*fp;  if((fp=fopen("empl.txt","r"))!=NULL)  {  while(!feof(fp))  {  fscanf(fp,"%s%d",a[i].name ,&a[i].age);  i++;  }  }  return i-1; } void writefile(struct employee a[],int n) {  int i;  FILE *fp;  if((fp=fopen("bsort.txt","w"))!=NULL)  {  for(i=0;i<n;i++)  {  fprintf(fp,"%s %d \n",a[i].name ,a[i].age);  }  } } void bubblesort(struct employee a[],int n) {  int i,j;  struct employee temp;  for(i=0;i<n-1;i++)  {  for(j=0;j<n-1;j++)  {  if(strcmp(a[j].name,a[j+1].name)>0)  {  temp=a[j];  a[j]=a[j+1];  a[j+1]=temp;  }  }  } } main() { ...

Slip 23_2: Read the data from file ‘sortedcities.txt’ containing sorted names of cities and their STD codes. Accept a name of the city from user and use binary search algorithm to check whether the name is present in the file and output the STD code, otherwise output “city not in the list”.
