The statement is:
Write a program that prints all entities of the form &name; (where name is formed of letters) appearing in the input, separated by one space.
Code:



	
Code:

	
#include <stdio.h>
#include <ctype.h>
#include <string.h>
#define MAX 100
int checkWord(char word[])
{
    size_t len = strlen(word);
    for(int i = 0; i < strlen(word); i++)
    {
        if(!isalpha(word[i]) || (word[0] != '&') || (word[len-1] != ';'))
        {
            return 0;
        }
    }
    return 1;
}
int main()
{
    char s[MAX];
    while(fgets(s, MAX, stdin))
    {
        char* word = strtok(s, " ");
        while(word != NULL)
        {
           // printf("%s\n", word);
           printf("%d\n", checkWord(word));
            if(checkWord(word) == 1)
            {
                printf("%s ", word);
            }
            word = strtok(NULL, " ");
            //printf("%s", word);
        }
    }
    return 0;
}






The program should work well but checkWord always returns 0 and never actually enters the if block. I don't understand what I'm missing, checkWord checks if the word is formed by letters only, starts with '&' and ends ';' but for the input:

john goes to &school; everyday

Output:

0

0

0

0 // this should be 1 and therefore &school; should be printed

0



What am I doing wrong?
