Programmer? Hell no. I'm a professional figure skater.

You can construct the value of any coin, using coins of lower value (if there are any); this makes the problem easier because the smallest amount of coins required is then obtained by repeatedly paying with the highest value coin, until the remaining cost is 0 (it would be diffent …

For C-Strings you could take a look at the [cstring library](http://www.cplusplus.com/reference/cstring/), which contains a function named *strlen*. While you're not looking for a user-defined function, you could also define it yourself as it's quite straight forward. It'd look similar to this: constexpr size_t strlen (const char text[]) { // Note: …

> After its standardization , array size can be specified with a variable. While C supports [VLAs](http://en.wikipedia.org/wiki/Variable-length_array) since the C99 standard, C++ does not support them as can be read in the [standard (8.3.4.1)](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2011/n3242.pdf).

Do you mean to do something like this? #include <stdio.h> #include <windows.h> static HHOOK _hook; static BOOL _control_pressed = FALSE; static const char _clipboard_text[] = "Hello world!"; static unsigned _clipboard_text_sz = sizeof(_clipboard_text); LRESULT CALLBACK LowLevelKeyboardProc(int nCode, WPARAM wParam, LPARAM lParam) { PKBDLLHOOKSTRUCT kb = (PKBDLLHOOKSTRUCT) lParam; HGLOBAL hGlobal; char* pGlobal; …

Right, so you have this figure of a certain height. When looking at the provided example you can clearly see there's some logic behind it; when asked to draw this figure of height 5 you'd be able to do it. So let's start with gathering information. We know how the …

> for loop. Is this loop supposed to have a body? Effectively, all it does is set x to 0. But since x = 0, when the program reaches the switch blocks nothing happens. The next for loop forms the body of this loop. > 1) Line 15 is a …

If `a` is an integer it doesn't (really) make much sense to do it.

What is there to explain? `malloc` (attempts to) allocate a given amount of memory on the heap. It doesn't really know (or cares) what you're going to put there so it returns a void pointer so you'll have to cast it to a pointer matching the data you're putting in …

normally an integer datatype hold 2 byes of memory.If Int is declared it holds 2 bytes by default. This is not true. The amount of bytes an integer takes up depends on the supported word size of the used CPU and there is no "default" specified in the specification. 32-bit …

Not having a compiler handy, so treat the following as kind-of pseudo code, but if performance is no requirement you could define it as bool isMono(const tNode* t) { if (t == NULL) return true; else return tsearch(t->info, t->left) == NULL && tsearch(t->info, r->right) == NULL && isMono(t->left) && isMono(r->right); …

That's some shady company asking their candidates questions like that..

`p` is an array of pointers. `*(p+i)` could be written as `p[i]` and `*(p[i] + j)` could likewise be written as `p[i][j]`. (So `*(*(p+i)+j)` could be written as `p[i][j]`) (and the contents of `p` are offsets off `a` which is 2-dimensional) So you could write that `printf` as: `printf("%d %d …

`'Hello'` should be `"Hello"`.

Your code is a mixture of C and C++ conventions, you should choose one or the other. As you posted this in the C section I assume you want C code. What do you want to do with newlines? Do you want to skip them entirely? You also don't have …

#include <stdio.h> int main(void) { const char* string_before = "f a1 2 5 ffffffde 23 fffffff1 4 b0"; const char* string_after = "f a1 2 5 de 23 f1 4 b0"; printf("The C-code resulted in: \"%s\".\n", string_after); return 0; }

I'm not fully sure if I get what you mean with your example, but I think you might be looking for a [map](http://www.cplusplus.com/reference/map/map/)? If not, please be more clear about what you mean with `list[i]` and `list[i_the_second]`.

You are comparing indexes to string values. In addition there seemed to be some logic mistakes. Here's an attempt to fix them for you: void fold(char s[], int l) { int i, j, foldHere; i = j = 0; foldHere = FOLDLENGTH; while (i < l) { // We are …
