#include 

char *strtokByWord_r(char *str, const char *word, char **store){
    char *p, *ret;
    if(str != NULL){
        *store = str;
    }
    if(*store == NULL) return NULL;
    p = strstr(ret=*store, word);
    if(p){
        *p='\0';
        *store = p + strlen(word);
    } else {
        *store = NULL;
    }
    return ret;
}
char *strtokByWord(char *str, const char *word){
    static char *store = NULL;
    return strtokByWord_r(str, word, &store);
}

int main(){
    char input[]="invest_#_1945_#_TRADE";
    char *array[3];
    char *p;
    int i, size = sizeof(array)/sizeof(char*);
    for(i=0, p=input;i
