C++ :: Adding Int To Struct Call
Feb 25, 2015
#include <cstdlib>
#include <iostream>
using namespace std;
struct height {
int feet, inches;
[Code] .....
I'm getting a succeed when i try to compile but my grow function is throwing me an warning that the + and - don't work in regards to grow function.
Basically i want it to grow a certain amount of inches specified and format the foot and inches if it goes over a foot. Can i not just add 1 to feet as it's an int? The same goes with inches.

I was attempting something weired with address to move data around when I discovered that the size of the array is not what I expected. I am passing this structure as &Users to a function that declares it as a void *, then I can deal with chunks of data (memmove) and not have to worry about index or things like that. However...sizeof is returning something I do not understand.

"
#include <stdio.h>
struct datastructure {
char character;
};
void function(struct datastructure** ptr);
[Code] ....
These codes give these errors:
error: request for member 'character' in '* ptr', which is of non-class type 'datastructure*'
error: request for member 'character' in '* ptr', which is of non-class type 'datastructure*'
These errors are related to
"
*ptr->character='a';
printf("Ptr: %c",*ptr->character);
"
I want to access "character" data inside the structure "trial" by a pointer to pointer "ptr" inside function "function",but I couldn't find a way to do this.

I just read and have known for a while that classes are private (members and inheritance) by default and structs are public. But my question then comes what if.. a struct inheriting from a class or a class inheriting from a struct?

I have decalred a password function which accepts an array as parameter but while compiling, it's showing an error wherever I have called it.
void password(char a[100])
{
if(::q==1) { cout<<"
Enter the master password : "; goto ENTER; }
[Code]....
Wherever I have called this function it's showing an error: "Call of nonfunction." One of the examples of the errors is below:
::q=1;
password(master_password);
//Both 'q' and 'master_password' being global variables, and master_password being array of size 25.

I wrote a program which detects a pattern in an array then returns a valve (x) for each time it does. now i tried to call function patt in main so that i can print x but it doesn't let me do it.
#include <stdio.h>
int patt(const int SIZE, char str[], int i, int c);
int main(void) {
const int SIZE=21;
char str[SIZE]={'1', '0', '1', '1', '0', '0', '1', '0', '1', '0', '1', '0', '0', '0', '1', '0', '1', '1', '0', '1'};

I want to write a function and be able to call it during execution (say during a while(1) loop). Is this possible without having to parse an input string to extract the function and parameters I need or is that the only way?

My program is crashing when I'm trying to call b = a. What has me confused is that when I call c = d = b, it all works fine.
I actually think I see it now that I posted this. In operator= I'm changing the size, but I'm not changing the size of the array that it's pointing to correct? I'm keeping it as 'p = new T[size]' rather than changing it to 'p = new T[x.size]' correct?
#include <iostream>
#include "Array.h
int main() {
std::cout << "creating Array< int > object a ...

I would like to get the this pointer by call by reference. Is this possible? I hoped to get it with this code, but it doesn't work:
Code:

public:
DemoClass();
int x;
void setParam(const DemoClass ¶m){
param=this;

I get always the error code "C2678". But I don't understand how I should change my code to avoid this.

The random method in here should return a random value inside given array.
The program constantly crashes when I send the array object as full.
It will only allow for you to choose the first 4 objects in the array, if you choose object number 8, for example, the program crashes.
So Im trying to send the pointer to the array instead. But now the compiler claims not to know of any such function.
static string getRandom(string* avalible[]){
cout << "Get random";
cout << "index: " << (*avalible)->length() << endl;
int index = random((*avalible)->length()-1);
cout << "returned" + index;

I can remove the "10" from the string first[10] but it doesn't make a difference.What is wrong with this?

I am trying to input a call by value in the second class. It will not compile with how it is currently and says that the pounds needs to be a different variable. Why is this? Is this close to a call-by-value or am I way off?
#include <iostream>;
using namespace std;
int main() {
int a, b, c, d;
cout << "Please enter your weight in Pounds and Ounces ";

When I call the member function in the main function, two functions are working fine but the third one(print()) is not. The program stops after executing the read_ages function and nothing printed on the screen. This is really strange and I could not find any problem after spending hours and had to post it here.It is a very simple program but I cant find the bug. It is a multiple file program and I am using MinGW as a compiler.
//File 1
#include<vector>
#include<string>
class Name_pairs {
private:
std::vector<std::string>names;
std::vector<double> ages;
[Code] ...
//I haven't made the sort function yet since I am stuck with the print(). Seems //like the compiler is skipping the print() function.
