Counting the word

[Chubby]

I dont know if this a right place to ask but anyway here you go:

I am trying count all occurrences word are that are in the file but i dont know how to do it but I can only do in like user have input in not from a file;

EX:

in file they have

the 50
is 20
on 5

and so on. but i couldnt get it to work.
I hope someone could help me out.

#include<stdio.h>
#include<conio.h>
#include<string.h>

void main()
{
	int i = 0, j = 0, count = 0;
	char str1[100], str2[20], str3[20];
	//clrscr();
	printf("Enter the text: ");
	gets(str1);

	printf("Enter word to count: ");
	gets(str2);

	while (str1[i] != '\0')
	{
		while (str1[i] != ' '&&str1[i] != '\0')	//copying the word from the text to a new string
			str3[j++] = str1[i++];

		str3[j] = '\0';	//assigning null character at the end of string
		j = 0;

		if ((_strcmpi(str2, str3)) == 0)	//comparing the given word with the copied word
			count++;

		if (str1[i] == '\0')
			break;
		else
			i++;
	}

	printf("No. of words are %d", count);
	_getch();
}

When you say 'couldn't get it work', is that you can't read the file or the count is incorrect or anything else?

[Chubby]

first on all i am new to C as you can see i ask user for input but thing is i want to get information file not from user;

like in file it store

50 the
20 so
10 on

it will print

50 the
20 so
10 on

and so on

code is working fine! I compile it and it run

[Chubby]

i dont know to store information and count at same time. also dont how to get compiler to read the file

[liuyang]

So you want to replace

printf("Enter the text: ");
gets(str1);

into something read whole content of a file?

[Chubby]

yes. like i say...

it will store "the" ; "so" and "on" and count it how many time it appear on file. NOT only the so on but it could be like i you me they where were,

[Chubby]

both

printf("Enter the text: ");
	gets(str1);

	printf("Enter word to count: ");
	gets(str2);

I'm going to provide you some functions to operate a file. But you'll have to combine them yourself.

To open a file for reading:

FILE *fp;
fp = fopen(filename, "rb");

To close a file:
fclose(fp);

To get the size of a file

long size;
fseek(fp, 0, SEEK_END);
size = ftell(fp);

To read the file into a string

char *buffer;
buffer = malloc(size + 1);
fseek(fp, 0, SEEK_SET);
fread(buffer, 1, size, fp);
buffer[size] = '\0';

[Chubby]

if you read into a sting how can you compare the word?

like the and the?

[Chubby]

i am confuse already

[Chubby]

#include<conio.h>
#include<string.h>

void main()
{
	int i = 0, j = 0, count = 0;
	char str1[100], str2[20], str3[20];
	//clrscr();
	FILE *openfile;
	if ((openfile = fopen("text.txt", "r")) == NULL)
	{
		return -1;
	}
	gets(str1);

	printf("Enter word to count: ");
	gets(str2);

	while (str1[i] != '\0')
	{
		while (str1[i] != ' '&&str1[i] != '\0')	//copying the word from the text to a new string
			str3[j++] = str1[i++];

		str3[j] = '\0';	//assigning null character at the end of string
		j = 0;

		if ((_strcmpi(str2, str3)) == 0)	//comparing the given word with the copied word
			count++;

		if (str1[i] == '\0')
			break;
		else
			i++;
	}

	printf("No. of words are %d", count);
	_getch();
}

[Chubby]

after that i dont get it

[Chubby]

here is what i did in c++
....

[liuyang]

Your first C program ASKS THE USER FOR A LINE, and them count the words.
Change that part to read the whole file. You don't have to change the rest of the code.

[Chubby]

you mean while loop and the two cout?

[liuyang]

First of all, write a short function to read whole content of a file

char* loadfile(const char *filename)
{
    char *buffer;
    // do it yourself
    return buffer;
}

then, replace

printf("Enter the text: ");
gets(str1);

with something like

str1 = loadfile("myfile");
