I have error with c function -

i new c, try write code , need deal string. need cut first word string, , need return the word , rest of string.

i wrote code cut first word getting error "segmentation fault (core dumped)" know why, how fix it? symbol equal " ".

char * cut(char *str, char *symbol) { int i=0;     static char *temp;   while (str[i]!=symbol[0])   {      temp[i]=str[i];      i++;     } printf("temp %s\n ",temp); return temp; } 

the posted code contains few problems. including undefined behaviour.

caveat: code assumes parameter str points nul terminated string.

#include <stdio.h>  // printf() #include <stdlib.h> // exit(), exit_failure #include <string.h> // strlen(), malloc()  char * cut(char *str, char *symbol) {     char *temp = null;     if( null == (temp = malloc( strlen(str)+1) ) )     { // malloc failed         perror( "malloc failed" );         exit( exit_failure );     }      // implied else, malloc successful      int i;     for(i=0; str[i] && str[i] !=symbol[0]; i++)     {         temp[i]=str[i];     }      // terminate string     temp[i] = '\n';      printf("temp %s\n",temp);     return temp; } 

however, question says return first word , rest of string neither posted code nor answer implement
