C/C++ :: Having Struct As Argument Parameter
Nov 24, 2014I am writing a text-based rpg and I'm having some issues trying to pass the player struct to a function. First, here are the relevant code snippets. Also, Player.c and Player.h aren't completed but the relevant function is. I just run tests every now and then to see if everything is working right.
Monster.h
#ifndef MONSTER_H
#define MONSTER_H
#include "Weapon.h"
typedef struct Player;
typedef struct {
char* mName;
[Code] ....
The errors are:
1. line 33 in Monster.h, the void Attack_Monster_Types(Monster* m, Player* p) the ide says missing ')' before '*', missing '{' before '*' and 'Player' name in formal parameter list illegal
2. line 18 in main.c when the attack function is called. it says 'Attack_Monster_Types' Undefined; assuming extern returning int.
I believe I have all the right headers included so I'm not sure what to do ....
C++ :: Why Default Argument For The Last Parameter Is Mandatory
Dec 1, 2014I faced a compilation error in the following code :
Code:
#include <iostream>
using namespace std;
void addition(int a, int b = 2, int c);
int main()
[Code]......
My question is that when i have called addition() with the 3rd argument, then what is the necessity of having the default argument for the 3rd parameter ?
Visual C++ :: Implementing Parameter Argument To Exe
Nov 5, 2013i have this Stealth Injector source from internet so this program is for injecting .dll to an .exe this program was made by someone to used for cheating in online game but i need to use this program in my private server game online to tell the game client .exe the server IP, that is stored in a dll file.. the problem is i don't want the player to directly execute this program, but they need to run the game patcher first to do the patch.. so i need to put some secret parameter argument that will block player from direct execute..
i know nothing about c++ i only know that you need to use main(int argc, char *argv[]) i've try to put something like this
Code:
int main(int argc, char* argv[]){
stringstream sparam;
string param;
[Code].....
the code works fine but the rest of code won't executed..
i've attached the cpp and header files for you guys to check source.rar
C++ :: Linked List Node Passed As Parameter / Argument Pointer To Pointer Notation
Jan 17, 2014I was having problems changing the value of my head node I passed it as an argument as head which would be the address. The parameter was defined as struct node *head. like this
bool deleteNode(struct node *head, struct node *delptr)
I tried manipultaing pointer values to change head node value but it did not work. I saw some code online which used pointer to pointers(in code below) to change head node value it worked I dont fully understand why. Would like better understanding of why.
Would also like to know why the argument call needed &head instead of just head.
remove = deleteNode(&head,found); opposed to remove = deleteNode(head,found);
#include "stdafx.h"
#include<iostream>
struct node{

C++ :: Function Parameter Scope - NumArray Not Recognized As Valid Parameter

C# :: Difference Between Char And Int
Feb 5, 2015Creating a C# program to prompt the user to choose the correct answer from a list of answer choices of a question and if the answer is wrong then try to prompt the same question again with do while loop but it is not working as it suppose to be.
class Program
{
static void Main(string[] args {
char UserChoice = ' ';
do {
Console.WriteLine("What is the command keyword to exit a loop in C#?");
Console.WriteLine("a.quit");
Console.WriteLine("b.continue");
[Code] ....
But if i use int instead of char in this program and replace a, b, c and d with 1, 2, 3 and 4 then this program work fine. What is wrong in this code when using char
C/C++ :: Difference Between Two Dates?
Oct 26, 2013How i can easly calculate the difference between two dates ?

Oct 30, 2013Other than the theoretical difference between cout and cerr where the former puts values to the monitor and the latter puts values related to errors to the monitor, is there any real difference here? Why not use cout when you want to send anything to monitor? Why use cerr at all?
View 7 Replies View RelatedC++ :: Difference Between Iterator And Pointer
Jan 21, 2013I just figured out that some std functions (for example: copy) need the resource and target objects have iterators to work. Otherwise, the compiler rejects. In case of two arrays, declared as:
double myA[100] = {};
array<double, 100> myB = {};
myA[0] is like a pointer, myB.begin() an iterator, if I do not make any mistake. So, what is exactly the difference between the pointer and the iterator here? They all give the access to elements.
If I need the target of copy to be an array like myA which cannot give an iterator, is there a way to make the command "copy" work for it?
C++ :: Difference Between Strings And Arrays?
Apr 10, 2013What is the diff between strings and arrays? Here is sample:
By String:

By arrays:

which is preferable and can i pick characters one by one in string?
C++ :: Inverted Difference Triangle
Jun 21, 2013Similar to Pascal’s triangle, the difference triangle has some interesting properties that find applications in various fields of the natural and applied sciences. In simple terms, a difference triangle is a set of integers arranged in an inverted triangle where each inverted triangle triad has its lower element equal to the difference (absolute value) of the two elements in the upper row. A difference triangle can be created from a sequence of integers forming the uppermost row by iteratively taking differences between consecutive terms to form the next row until a single-element row is created.
Example Consider the sequence 5, 8, 13, 21, 34, 55 from the Fibonacci series as the uppermost row of the difference triangle. The difference between successive elements form a new set: 3 (= 8 – 5), 5 (= 13 – 8), 8 (= 21 – 13), 13 (= 34 – 21), and 21 (= 55 – 34). The process can then be repeated until there is only one element left giving the following difference triangle:
5 8 13 21 34 55
3 5 8 13 21
2 3 5 8
1 2 3
1 1
0
Problem Write a program that forms a difference triangle using a given series of numbers as topmost row.

C/C++ :: Computing Bit Difference Between Two Arrays?
Jul 23, 2014#include <stdio.h>
#include <stdlib.h>
int b_diff (int, int);
[Code].....
I am trying to take two arrays H[], and V[] and call each element to compute the bit difference(Hamming distance) and return that back to the main function to be used in calculating pixel_phase and pixel_smoothing. I'm getting an error that bit_diff cannot be used as a function and I've tried renaming it but nothing seems to work.
[ int b_diff (int a, int ] is how it should actually look.int b_diff (int a, int is how it should actually look).
