Explanation / Answer

void extract(char hyperlink[], char address[])

{

int i =0,z=0;

int found =0, start=0,end=0;

for ( i = 0; i < strlen(hyperlink); i++)

{

if (hyperlink[i] == '"' && found ==0)

{

start = i;

found =1;

}

if (found ==1 && hyperlink[i] == '"')

{

end = i;

}

}

for (i=start+1; i < end; i ++)

{

address[z] = hyperlink[i];

z++;

}

}

int main(int argc, const char * argv[])

{

char hyperlink[100];

char address[100];

printf("type the link: ");

scanf("%s", hyperlink);

extract(hyperlink, address);

printf("%s", address);

printf(" ");

printf("address length: %lu characters", strlen(address));

printf(" ");

}
