Thread: String comparison troubles: mary != mary

For some reason my method of comparing string is wrong or there is something wrong with my strings. My output looks like this:

Code:

parent(bob,mary)You want to check if bob is a parent of mary
Looking for childnode
mary == mary
peter == mary
john == mary

and here is the snippet of the relevant code:

Code:

 
char *arg1,*arg2;
char *tmp;


strtok(buffer,"(");    
tmp=strtok(NULL,",");
arg1 = strdup(tmp);
tmp=strtok(NULL,")");
arg2=strdup(tmp);
parent(hp,arg1,arg2);

Code:

int parent(struct family *hp, char* parent, char* offspring){

  struct family *cp = hp;
  while(cp->child){
    cp=cp->child;
    printf("%s == %s\n",cp->name,offspring);
    if(strcmp(cp->child->name,offspring) == 0){
      printf("found the child\n");     
      break;
    }
  }
  if(cp->parent1->name == parent)
    return 1;
  else if(cp->parent2)
    if(cp->parent2->name == parent)
      return 1;
  return 0;
}

Even after printing out mary == mary, the program does not execute the "found the child" printf and continues traversing the tree. I think the problem is with the strings.
