How to count specific words in a text file

Question

i am unable to get the specific words. my code:
```
#include <stdio.h>
#include <string.h>

int main()
{
FILE *fp;
char filename[100];
char ch;
int linecount;

linecount = 0;

printf("Enter a filename :");
gets(filename);

fp = fopen(filename,"r");

int match( char *word )
{
char *targets[] = {"auto", "the", ""};
char **t = targets;

while ( *t[0] != '\0' && strcmp(*t, word))
t++;

return *t[0] != '\0';
}

if ( fp )
{

while ((ch=getc(fp)) != EOF) {

if (ch == '\n') { ++linecount; }

}

if (linecount > 0) {
++linecount;
}
}
else
{
printf("failed to open the file\n");
}

printf("Lines : %d \n", linecount);

return(0);
}
```
the task is to count the number of lines and specific words present in a text file. i was unable to count the specific words present in the text file. could anyone help me with it. Thanks in advance.

Answer 1

How u wrote that function match inside of main, i think it should be maintained at outside, and u need to do some extra work there, when ever space or tab space or new line is encountered, upto that point what the characters u read i.e word should be compared using that match function

check this out:
#include <stdlib.h>
#include <ctype.h>
#include <string.h>
#include <stdio.h>

int main()
{
FILE *fp;
char filename[100];
char ch;
int linecount, wordcount;

linecount = 0;
wordcount = 0;

printf("Enter a filename :");
gets(filename);

fp = fopen(filename,"r");

if ( fp )
{

while ((ch=getc(fp)) != EOF) {

if (ch == ' ' || ch == '\n') { ++wordcount; }

if (ch == '\n') { ++linecount; }

}

if (wordcount > 0) {
++linecount;
++wordcount;
}
}
else
{
printf("failed to open the file\n");
}

printf("Lines : %d \n", linecount);
printf("Words : %d \n", wordcount);

return(0);
}

int getNextWord( char *target, size_t targetSize, fp )
{
size_t i = 0;
int c;

while ( (c = fgetc( fp )) != EOF && i < targetSize - 1 )
{
if ( isspace( c ) )
{
if ( i == 0 )
continue;
else
break;
}
else
{
target[i++] = c;
}
}

target[i] = 0;
return i > 0;
}

int match( const char *word )
{
const char *targets[] = {"and", "the", NULL};
const char *t = targets;

while ( t && strcmp( t, word ))
t++;

return t != NULL;
}

#define MAX_WORD_LENGTH 10

char word[MAX_WORD_LENGTH + 1];

while ( getNextWord( word, sizeof word, fp ))
{
if ( match( word ) )
count++;
}
printf("%d",count);
