help with c program to count # of words in a string

Oct 12th, 2004

I am kinda new to world of c programming, and i have been assigned a problem that is written as follows: Write a procedure that counts the number or words in a string. Write a program to test your new procedure. I am kinda lost on this completely. Any help on how to define the number of words by the amount of spaces. How do i define a word? Where do i want to start. I figure it will involve some form of looping and a counter. Any help will be greatly appreciated

This sounds like a simple string. I know nothing about C, but I know you'll need a string or function for this.

Look through any docs or manuals you can find. It would be something like count$() but dont rely on me, im a newbie too

I had the same assignement 1 month ago

Here's the code :

#include <stdio.h>
#include <string.h>
#define SIZE 100
 
int count(char vector[],int nr);
 
int main()
 
{  
     int i,string_size,x; 
     char string[SIZE]; 
     printf("Type a text: ");
     gets(string);
     string_size=strlen(string);
     x=count(string,string_size);
     printf("Number of words: %d\n",x);
 
     return 0;
}
 
int count (char vector[],int nr)
 
{
    int gasit=0,i; 
    for(i=0;i<nr;i++)
    {
        if(vector[i]>='a' && vector[i]<='z') gasit++;
          if(vector[i]>='A' && vector[i]<='Z') gasit++;
    }
 
    return gasit;
 
    }
#include <stdio.h>
#include <string.h>
#define SIZE 100

int count(char vector[],int nr);

int main()

{  
     int i,string_size,x; 
     char string[SIZE]; 
     printf("Type a text: ");
     gets(string);
     string_size=strlen(string);
     x=count(string,string_size);
     printf("Number of words: %d\n",x);

     return 0;
}

int count (char vector[],int nr)

{
    int gasit=0,i; 
    for(i=0;i<nr;i++)
    {
        if(vector[i]>='a' && vector[i]<='z') gasit++;
          if(vector[i]>='A' && vector[i]<='Z') gasit++;
    }
   
    return gasit;

    }

Good luck

    }
   
    return gasit;

}

I think there is a better way of doing this, just use the [search]isalpha( )[/search] function which checks whether the given character is an alphabet or not. You require ctype.h header file to use this function.

Hope it helped, bye.

Very nice tip

You were right , it's much easier and simple with isalpha()
Here's the new version:

 Help with Code Tags 
 C Syntax (Toggle Plain Text) 
#include <stdio.h>
#include <ctype.h>
#include <string.h>
 
int main()
{
    char string[100];
    int i,found=0;
 
    printf("Type a string : ");
    gets(string);
 
    for(i=0;i<strlen(string);i++)
        if( isalpha(string[i]))
                    found++;
    printf("Number of characters: %d\n",found);
 
    return 0;
}
#include <stdio.h>
#include <ctype.h>
#include <string.h>

int main()
{
    char string[100];
    int i,found=0;
    
    printf("Type a string : ");
    gets(string);

    for(i=0;i<strlen(string);i++)
        if( isalpha(string[i]))
                    found++;
    printf("Number of characters: %d\n",found);

    return 0;
}

Thanks ~s.o.s~

Ah... looks like it missed my eye.

@Eko:
Hey there buddy, normally its a bad programming practice to use the function gets( ) since it does no bound checking i.e. even if you declare your string to be consisting of 10 characters, nothing prevents you from entring 100 characters. This will result in buffer overflow and writign to memory that doenst belong to you which in the end leads to corruption.

You are better off using fgets( ).

 Help with Code Tags 
 c Syntax (Toggle Plain Text) 
char buffer[BUFSIZ] = { '\0' } ; // set character array to all null chars
printf( "Enter string: " ) ;
fgets( buffer, BUFSIZ, stdin ) ;  //
char buffer[BUFSIZ] = { '\0' } ; // set character array to all null chars
printf( "Enter string: " ) ;
fgets( buffer, BUFSIZ, stdin ) ;  //

[search]fgets( )[/search]
The above is a much safer way of accpeting strings or a matter of fact any input from the user.

Dont forget to remove the newline character which is present at the string end.

Offtopic :
@ iemtwhee I don't know what u find so funny ; if you are so "advanced" , go write a c programming book or something :lol:

@~s.o.s~ Thanks for the support,i heared about fgets(),but our teachers at the university want us to use the gets() function and if u don't do it their way,than is the highway :lol:
