I have a stack that will hold a BIGINT. A bigint is a struct that has a char array that will hold our numbers, and some other values. So I made my stack, and everything worked well from the STDIN, but when I try to add a a bigint, it seems like nothing is being added. here is my push_stack()
code:
void push_stack (stack *this, stack_item item) {
if (full_stack (this)){realloc_stack (this);}
this->data[this->size] = strdup(item);
this->size++;
}
Here is my stack
structure:
struct stack {
size_t capacity;
size_t size;
stack_item *data;
};
Here is my bigint
structure:
struct bigint {
size_t capacity;
size_t size;
bool negative;
char *digits;
};
bigint *new_string_bigint (char *string) {
assert (string != NULL);
size_t length = strlen (string);
bigint *this = new_bigint (length > MIN_CAPACITY ? length : MIN_CAPACITY);
char *strdigit = &string[length - 1];
if (*string == '_') {
this->negative = true;
++string;
}
char *thisdigit = this->digits;
while (strdigit >= string) {
assert (isdigit (*strdigit));
*thisdigit++ = *strdigit-- - '0';
}
this->size = thisdigit - this->digits;
trim_zeros (this);
return this;
}
And now my additon to the stack:
void do_push (stack *stack, char *numstr) {
bigint *bigint = new_string_bigint (numstr);
show_bigint(bigint);
push_stack(stack, bigint);
}
For some reason, my bigint
will not add to the stack. Any help is appreciated.
