I've never bothered to inline any function, and I'm fairly unfamiliar with how it works. I was wondering, would this function benefit from being inlined?
const char* GetNameByID(int ID)
{
auto itor = std::find(Achievements.begin(),Achievements.end(),ID);
if(itor != Achievements.end())

I'm very new to C. I have extensive experience with C# and very little with C++, but basically none with C.
I wrote a small program that declares a singly-linked list struct, a few methods operating on the list, and then uses it from the main method. Even though I've read about it a lot, this is...
The LinkedList nodes can be 1-->2-->3-->4, where --> indicates next. For their random pointers: 1--> 2, 2--> 4 3-->2 4--1. There can be duplicate data values of the nodes. I'm looking to see if the solution can be improved upon.
class Node
{
int data;//Node data
Node next, random;//Next and rand...
This is a smple reworking of the Bash date command to my own personal liking. It's possibly a rather trivial task, but I just wanted the date and time to be in the form of:
Fri Sep 2 2016
11:37 P.M.
I think this accomplishes that:
#!/bin/bash
today() {
now="$(date | awk '{ OFS=" ";...
I've made a JavaScript library that retrieves a Google Spreadsheet. It's a something like Sheetrock.js, while mine is just a prototype, less powerful.
I've uploaded the source code and example in GitHub.
But you can just see the implementation and demo in JSFiddle. A sample spreadsheet is here

I'm not sure how to go about creating a boolean method which checks if the array provided is complete binary tree.
My code already checks if its a binary tree.
I'm new to programming and would really appreciate any help.
Given that I have a serial of vectors \$\{\mathbf U_1,\mathbf U_2,\cdots,\mathbf U_n\}\$. Below is a simple instance U1, U2, U3
U1 = {0.25, 0.25, 0.5, 0.5, 0.75, 0.75, 0.8};
U2 = {0.21, 0.25, 0.3, 0.6, 0.7, 0.8};
U3 = {0.25, 0.3, 0.7, 0.8};
Now I would like to calculate their common vector , i...
My friend and I had a discussion over freeing dynamically allocated memory. He told that a memory could be freed with realloc(), to which I denied.
Let's consider the below code:
int main()
{
int *p = (int *)malloc(sizeof(int) * 10);
int *q = (int *)malloc(sizeof(int) * 10);
free(p)...

Hi I am trying to identify matching consecutive numbers in Java using a for loop. My code first establishes a binary number of base 10 (n) but I cannot figure out how to identify matching consecutive numbers.

I am trying to build a multiple file uploader with jQuery and Ajax. I would like to know how this code could be improved. I feel the client side validation of file types in my code are presently not good enough.

I've read that I should avoid the postfix increment operator because of performance reasons (in certain cases).
But doesn't this affect code readability? In my opinion:
for(int i = 0; i < 42; i++);
/* i will never equal 42! */
Looks better than:
for(int i = 0; i < 42; ++i);
/* i will...
Always code for the programmer first and the computer second.
If there is a performance difference, after the compiler has cast its expert eye over your code, AND you can measure it AND it matters - then you can change it.
