Thread: string problem

i got a string that looks lie hello(you) which is '\0' terminated.

now i want to extract the words (means splitting it at ( and ).
i wrote the following:

Code:

while(word[i] != '\0') {
				while(word[i] != '(' && word[i] != ')' && word[i] != '\0')
					++i;
				if(word[i] == '(' || word[i] == ')') {
					word[i] = '\0';
					printf("%s | ",word[j]);
					j = ++i;
				}

it crashes. any idea?

printf("%s | ",word[j]);

Change to:

printf("%s | ",&word[j]);

ou, that hurts.

thanks

try this one...

Code:

int extract(char *src,char *dest,int dest_sz) {
	char *psrc =src;
	char *pdst = dest;	
	while(*psrc && *psrc!='(') {
		psrc++;
	}
	if(!*psrc) return -1; /*ERROR! '(' not found*/
	psrc++;
	while(*psrc && *psrc!=')') {
		if(pdst - dest >=dest_sz)
			break;/*dest is out of memory*/
		*pdst = *psrc;
		psrc++; 
		pdst++;
		
	}
	*pdst = '\0';

	return pdst - dest; /*return the strlen of the dest*/
}

and this below is upgraded version
with different delimiters:

Code:

int extract(char *src,char *dest,char dlm[3],int dest_sz) {
	char *psrc =src;
	char *pdst = dest;	
	while(*psrc && *psrc!=dlm[0]) {
		psrc++;
	}
	if(!*psrc) return -1; /*ERROR! '(' not found*/
	psrc++;
	while(*psrc && *psrc!=dlm[1]) {
		if(pdst - dest >=dest_sz)
			break;/*dest is out of memory*/
		*pdst = *psrc;
		psrc++; 
		pdst++;
		
	}
	*pdst = '\0';

	return pdst - dest; /*return the strlen of the dest*/
}

Code:

/*TEST*/
int main(void) {
   char str[] = "This is a (test) {string}";
   char dest[200];
   int len=0;
   len = extract(src,dest,sizeof(dest));
   printf("\"%s\" -> \"%s\"\n",str,dest);

   len = extract(src,dest,"{}",sizeof(dest));
   printf("\"%s\" -> \"%s\"\n",str,dest);
}
