The semantics of tpalloc() and tprealloc() are such that the larger of the following two values is used to create or re-allocate a buffer: the value of dfltsize() or the value of the size parameter for the tpalloc() and tprealloc() functions. For some types of structures, such as ...
char *tmp = realloc(str, sizeof(char) * length + 1 /* or no +1 */);can shrink the allocation. which makes a laterif (length == size)invalid (the true allocation size is smaller) and sostr[length++] = inputch;lost memory access protection. Updatesizeto fix that hole. +1not ne...

We illustrate the realloc function in the section Using the realloc Function to Resize an Array. Note Arrays have a fixed size. When we declare an array, we need to decide how big it should be. If we specify too many elements, we waste space. If we specify too few elements, we limit...
