Counting words in a string - c programming

Question

I need to write a function that will count words in a string. For the purpose of this assignment, a \"word\" is defined to be a sequence of non-null, non-whitespace characte

Answer 1

Here is another solution:

#include 

int words(const char *s)
{
    const char *sep = " \t\n\r\v\f";
    int word = 0;
    size_t len;

    s += strspn(s, sep);

    while ((len = strcspn(s, sep)) > 0) {
        ++word;
        s += len;
        s += strspn(s, sep);
    }
    return word;
}
