Yes, it's possible. The destination array needs to be large enough to hold the replacement, and the process is rather manual. You'll shift everything to the right of the matching character to make a hole, then overwrite what was in the hole with the new data: [code] # Find 'e' …

[QUOTE] In terms of why, my only possible explanation is that there is a different implementation for operator+ and operator+=???[/QUOTE] Consider that operator+= returns a reference to the current object while operator+ returns a new string object.

What results were you expecting?

This is a different matter entirely. The question you linked to was specifically about not printing a line break after hitting the Enter/Return key. Your requirement is merely not to print a newline character, which you're already doing.

You could probably simplify the file operations. What is this program supposed to do?

I have no idea what you're trying to say (what the hell is "return a book" supposed to mean?), but the file failed to open when fopen returns NULL, not the other way around. Your if statement is reversed.

You're a [I]second[/I] year CIS student and don't even know where to start? I weep for this generation of programmers. How about starting with one account class and working out the credit/debit actions? From there you can add more accounts, set up branches, etc... This project practically slaps you in …

addinf and address are both pointers to structures, so you'd need to dereference the pointer before accessing members: [code] (*(*stud.addinf).address).housenumb = 123; [/code] Alternatively, the arrow operator does this for you in a much more convenient manner: [code] stud.addinf->address->housenumb = 123; [/code] Note that those pointers must point to something …

[QUOTE]why is it allowed to store chars in ints.[/QUOTE] [ICODE]char[/ICODE] is an integer type, just with a smaller range than [ICODE]int[/ICODE]. It makes sense that since [ICODE]int[/ICODE] can hold every value [ICODE]char[/ICODE] can, a widening conversion from [ICODE]char[/ICODE] to [ICODE]int [/ICODE]should be possible.

Read characters until a newline or EOF is reached: [code] int ch; do ch = getchar(); while (ch != '\n' && ch != EOF); [/code] This is the only portable method, but it also has a downside of blocking for input if the stream is already empty when the loop …

The file names are irrelevant. What is you [I]class[/I] called?

You didn't post enough code for me to be sure, but from the error I'd guess filePath is a data member and you're doing something like this: [code] ref class Form1 { String^ filePath = this->listView1->CheckedItems[0]->SubItems[2]->Text; // ... }; [/code] C++ doesn't work like that though, you want to do …

What does your archive file format look like? A simple format would consist of records like so: [code] struct record { size_t size; unsigned char *bytes; }; void write_record(FILE *out, struct record *rec) { fwrite(rec->size, sizeof rec->size, 1, out); fwrite(rec->bytes, 1, rec->size, out); } int read_record(FILE *in, struct record *rec) …

That code shouldn't compile at all, much less output the wrong value. Try this program and see if you get the same erroneous output: [code] #include <stdio.h> int main(void) { int a = 10, b; b = (a >= 5) ? 100 : 200; printf("%d\n", b); return 0; } [/code]

Turbo C is a 16-bit compiler, which essentially means that the actual range of int is [32,767, -32,768] (16 bits, two's complement). It simply can't handle 800000, but long can. The fix in your case is to change your code to use long instead of int. As a side note, …

A forward declaration does nothing but introduce the name of a type into the current scope. Headers typically provide full declarations, which include member information as well as the type name.

Assuming your ints are 32-bit, FFFFFF01 exceeds INT_MAX. strtol should correctly return INT_MAX because the value passed in is out of range. While I'm sure you expected strtol to take a value with the sign bit set and produce a negative value, that's not how it works. The values are …

[QUOTE]Is this right to say Heap is RAM and Stack is Pagefile(HardDrive)?[/QUOTE] No. Both are RAM-based and both can be swapped into virtual memory if they exceed limits. However, the stack size is not dynamic, so it's less likely to dip into virtual memory than the heap. You can set …

Some of your function definitions have a rogue semicolon before the opening brace. Clearly you copy-pasted the declaration and forgot to remove the semicolon.

Your thread class is somewhat confusing because it manages all threads.
