C program to read a text and count occurrence of a particular word?

Answer 1

#include<stdio.h>

main()

{

int i,words,spaces;

char a[30];

printf("enter the string") ;

scanf("%s",a);

for(i=0;a[0]!="\0";i++)

{

if (a[i]=' ')

spaces++;

}

printf("the no. of spaces in the string is %d",spaces);

printf("the number of words in the string is %d",spaces+1);

}

Answer 2

how to find the frequency of words in a sentence?

//program to find occurence of a word in a sentence

import java.io.*;

public class cnt2

{

public static void main(String args[])throws IOException

{

int times=0,count=0,x=0,no=0;

InputStreamReader ir=new InputStreamReader(System.in);

BufferedReader br=new BufferedReader(ir);

String s,w;

System.out.println("Enter the sentence:");

s=br.readLine();

System.out.println("Enter the word:");

w=br.readLine();

try{

for(int i=0;i<s.length();i++)

{

if(w.charAt(0)==s.charAt(i))

{

for(int j=0;j<w.length();j++,i++)

{

if(s.charAt(i)==w.charAt(j))

{ count=count+1;}

if(count==w.length())

{no=no+1;count=0;};

}

}

}

catch(Exception e){}

if(no==0)

{

System.out.println("word is not present");

}

else

{

System.out.println("word is present "+no+" times");

}

}

}

#include<iostream.h>

#include<conio.h>

#include<string.h>

char temp[30][30];

int check(char x[],int n)

{

for(int i=0;i<n;i++)

{

if(strcmp(temp[i],x)==0)

return 0;

}

return 1;

}

void main()

{

char a[100],b[20],ch,c[10][10];

int i=0,j,n=0,k=0,count,m;

clrscr();

cout<<"\n Enter any string and end with $::";

cin.get(ch);

do

{

a[n]=ch;

n++;

cin.get(ch);

}while(ch!='$');

a[n]='\0';

for(;;)

{

for(j=0;(a[i]!=' ')&&(a[i]!='\0');j++)

{

b[j]=a[i];

i++;

}

b[j]='\0';

strcpy(c[k],b);

k++;

if(a[i]==0)

break;

i++;

}

cout<<"\n\n------------------------------------\n";

cout<<"\n\tword\tFrequency\n";

cout<<"\n\n------------------------------------\n";

for(i=0;i<k;i++)

{

count=1;

m=check(c[i],i);

for(j=i+1;j<k;j++)

{

if(strcmp(c[i],c[j])==0 && m==1)

count++;

}

if(m==1)

{

strcpy(temp[i],c[i]);

cout<<"\t"<<c[i]<<"\t"<<count<<endl;

}

}

cout<<"\n\n------------------------------------\n";

getch();

}
