In Mumbai, we step through the code with the debugger to resolve such issues (if I remember it right, they do the same at Rome, but I'll leave it to Carlo to confirm).

It's ok, but what do you do in Bangalore? (In Milan, I suppose, they ask to a Rome-based developer to do the job).

I suppose as long as someone uses the debugger, the job gets done.

i wrote the code below for a C++ programming class and i get a segmentation fault within this part of the code. now i asked my teacher and he told me that there's just a line in the wrong place but for the life of me i can't figure out which line is out of place. i thought i'd turn to some people with more experience with looking at code and finding the errors. it's really a simple problem i have i'm just not seeing it though.. please help me!
p.s. sorry if i posted the code the wrong way for the forum
void Search::Store(char *k, char *d) {
struct TBox *p1,*p2;
int i;
p1 = new TBox;
if (Start==NULL) {
p1->left = NULL;
p1->right = NULL;
p1->key = new char[strlen(k)+1];
p1->data = new char[strlen(d)+1];
strcpy(p1->key,k);
strcpy(p1->data,d);
Start=p1;
return;
p1=Start;
while(p1!=NULL) {
if ( (i=strcmp(k,p1->key)) == 0 ) {
delete [] p1->data;
p1->data = new char[strlen(d)+1];
strcpy(p1->data,d);
return;
}
if ( i < 0 ) {
p2=p1;
p1=p1->left;
continue;
}
p2=p1;
p1=p1->right;
}
}
p1 = new TBox;
p1->left = NULL;
p1->right = NULL;
p1->key = new char[strlen(k)+1];
p1->data = new char[strlen(d)+1];
strcpy(p1->key,k);
strcpy(p1->data,d);
Start=p1;
if (i<0) p2->left=p1;
else p2->right=p1;
return;
}

Why didn't you check if memory allocation succeeded?

What is the purpose of the return; line? Do you know the code below it will never be executed?

ok so what should i do with the return? yes i see that anything after it won't be executed but do i need to put that return at the bottom of this function or is it unecessary?

You didn't answer my question: What is the purpose of the intermediate return;? Do you really want to cut-off the remaining lines? As for the return; at the bottom of the function, it is optional (old saying: "leave out all the optional stuff").

That's not promising...

You should definitely use a debugger and find the offending line.

Get with the times, man - new throws when it fails...so long as you're not using VC6! Certainly, in VC++ 2003 and later, this code prints Whoops - not enough memory!:
try
{
int* a = new int[1e9];
}
catch(std::bad_alloc)
{
std::cout << "Whoops - not enough memory!\n";
}
