c - To count the number of letters in a word and no of words in a sentence -

i trying experiment counting number of letters in word.to distinguish between words in string checking blank spaces.if encounters blank space 1 word , has respective letters. example "hello world". output supposed like

o/p hello has 5 letters world has 5 letter 

but when trying write code getting segmentation fault. below code.

#include <stdio.h> #include <string.h>  main(void) {      int nc = 0;     int word = 0;      char str[] = "this test";     int len = strlen(str);     int i;     for(i = 0; < len; i++)     {         ++nc;         if(isspace(str)){                      ++word;            }      }      printf("%d\n",nc);  } 

try this..

for(i = 0; < len; i++) {    if(isspace(str[i]))    {        ++word;        continue;    }   ++nc; }  if(len>0) word++;  printf("%d %d\n",nc, word);
