c - How to delete specific words from char array? -

-

so task char array delete these words starts , ends same letter. , @ point program crashes. here function:

void removesame(char * start) {   int i, j, first, last, k;   (i = 1; < line_length; i++) {     if ( * (start + i) != ' ') {       first = * (start + i);       (j = i; j < line_length; j++) {         if ( * (start + + j + 1) == ' ') {           last = * (start + + j);         } else {           break;         }       }      }     (; != j; i++) {       k = j - i;        * (start + k) = "\0";     }   } }

and here full code http://pasted.co/22566eb6

as other mentioned:

changing * (start + i) start[i] improves readability

"\0" should '\0' or 0 - in c, double quotes used represent strings, , strings memory addresses.

array indexes start 0

also keep in mind strings write in clear in source (ex: "abcba string") constant strings (const char*) , must copied other location in order modify them.

void removesame(char * start) {     int i, j, k;      (i = 0; start[i];) { // advance while haven't reached string's end         if (start[i] != ' ') {             (j = + 1; ; ++j) {                 if (start[j] == ' ' || !start[j]) { // advance until find word                     if (start[i] == start[j - 1]) {                         (k = i; (start[k] = start[k + j - i]); ++k); // delete word                     }                     else {                         = j;                     }                     break;                 }             }         }         else {             ++i;         }     } }
