Hello all, It's been a while since I have worked with C++, I'm currently catching up for an upcoming programming test. I have the following function that has this signature: void MyIntToChar(int *arrayOfInt,char* output) Int is an array of integers and char* output is a buffer that should be long enough to hold the string represent...

I'm a little new to pseudocode. I understand what the code is saying, but having a hard time putting the pieces together. How should I be thinking to understand what this code is doing: Suppose that a1, a2, . . . , ak is an array of k numbers. What does the following code fragment do? Briefly explain why. Assume that all the indented li...
I just finished a homework problem for Computer Science 1 (yes, it's homework, but hear me out!). Now, the assignment is 100% complete and working, so I don't need help on it. My question involves the efficiency of an algorithm I'm using (we aren't graded on algorithmic efficiency yet, I'm just really curious). The function I'm about to...
Hey all, I feel bad about asking a question so simple, but I can't figure this out for the life of me. I need to construct a NFA based on some languages, and the only one I can't figure out is this one: L = (10)* Note that I am not asking for any help concerning the FSM, but only some clarification on what the language represents. ...

Hi, I am trying to get better at c++. I have a Test class and below code in main(). Test *pObj = new Test(); If we debug by steping one by one instruction, First it goes to new function to allocate memory, then it calls constructor. Then it comes back to main() function. As we all know, constructor does not return anything. In that ca...
Hi, I have below piece of code class Test { public: Test(){} Test(int i) {} void* operator new (size_t size) { void *p = malloc(size); return p; } //void* operator new (size_t size, Test *p) //{ // return p; //} }; int main() { Test *p = new Test; int i = 10; new(p) Test(i); } Above p...
VHDL code First of all, sorry for the redirect, but it's easier that way. I'm building a digital clock, but as you can see, clock_AN and clock_seg_out do not change. Is this caused by a wrong port mapping? Thanks! ...
Hi, I am just trying to check whether compiler allows type name as variable name. When i tried int int; It reported an error saying error C2632: 'int' followed by 'int' is illegal But when i tried #include <string> using namespace std; int main() { string string; } It didn't give any error. Both string and int are...
I am taking a programming class in C# and here is my first assignment, and already I am in need of help. I think I can handle the problem I just need help getting started.

I am really getting confused on how pointers work. I am trying to write short little programs that will illuminate exactly how they work and I am having some troubles. For example: char c[3]; //Creates an array of 3 bytes - the first 2 bytes can be used for characters and the 3rd would need to be used for the terminating zero *c = 'a...
