Code:

Could I possibly use malloc to allocate memory for the stack too?

C/C++ :: How To Implement Pointers To Call The Function
Mar 11, 2014write a program which contains two global variables:
1.Account number (integer)
2.Account Balance (float)
and three functions :
A function called set values which sets initial values for account number and account balance,
A function called set values which prompt user to enter the values of the above variables,
A function called input transaction which reads a character value for transaction type that is D (for deposit) and W (for withdrawal ) and a floating point value for transaction amount which updates the account balance .
Implement a pointer to call each of the functions using C++.
C++ :: Implement Simple Wrapper For Logging Function
Jul 22, 2014I need to implement simple wrapper for logging function log(const char *). So the solution is below:
#include <stdio.h>
#include <sstream>

void log(const char * str){ printf(str);}
[Code] ...
So, according to standard the temporary objects should not be destroyed before full expression execution (expression whitch is not a part of another expression).
The question is: is StreamLogger() << "foo1" << "foo2" << "foo3"; full expression or not?

C++ :: Singleton Base Class - How To Implement GetInstance Function
Aug 20, 2014I'm playing with the idea of a singleton base class, but I'm having an issue with how to implement the GetInstance() function in the base class. Since I'm trying to make this ridiculously simple for the child, I'd like to handle that in the base.
class Singleton {
private:
static Singleton* instance;
Singleton() { Construct(); } // Private to avoid other instances
[Code] .....
It would be easy to use like so:
class Hello : public Singleton {
private:
std::string hello;
void Construct() { hello = "hello"; }
public:
std::string GetHello() const { return hello; }
};
Then the instance would be handled like so:
std::cout << Hello::GetInstance()->GetHello();
C++ :: Implement Member Functions Of Class Function - Failing To Get Input

View 4 Replies View RelatedC++ :: Function To Find Out Iterator Of Certain Value In Vector
Sep 4, 2013I defined the following function to find out the iterator of a certain value in the vector. I defined it as such so if the value exist in the vector then return a iterator of it, if not then return a pointer pointing to nonsense.:
vector<tIndex_t>::iterator unlabelTit(const tIndex_t index) {
for(vector<tIndex_t>::iterator it=unlabelT.begin(); it<unlabelT.end(); it++) {
if(index==*it) return it;
} return NULL;
}
But looks this one is not accepted by compiler, saying I cannot do this kind of comparison like:
unlabelTit(i)!=NULL;
so I just delete the return NULL; and then the compiler giving me warning about no return statement before }.
a pointer pointing to nonsense? how to do that?
C/C++ :: Using Function To Find Mode Of Array?
Oct 20, 2014My code seems to find the mode of the array I input sometimes. Sometimes it gives me the wrong number or multiple numbers. It just all depends on what is number is inputted into the array. I don't know what the problem is. I tried looking online and editing many times and can't find the answer. Maybe I'm overlooking something or doing something wrong. Here's my code.
#include <stdio.h>
void readArray(int arr[], int length)
{
printf("Enter data:
");
[Code].....
Maximum: 15
Mode: 2
As you can see the mode is clearly not 2 and I do not know why.

C/C++ :: Find Max And Min Value In Void Function Using Pointers
Aug 31, 2014I'm having issues with pointers and relationship operators in C.
I need to find a max and min value in a void function using pointers. max and min would work if they had values. mul works, because you can just do math operations with pointers.
There are 0 errors and warnings; but max and min are never going to work as is.
Clearly I'm missing something.
#include <stdio.h>
#include <stdlib.h>
void max(int *a, int *b, int *c, int *d, int *result);
void min(int *a, int *b, int *c, int *d, int *result);
void mul(int *a, int *b, int *c, int *d, int *result);
int main()
[Code]...
Your job will be to create a program that uses pointers. Your output must be done in the main function and the calculations MUST be done in the three functions. Therefore you MUST use pointers correctly.
You must declare and implement the following 3 functions. Below are the three prototypes that you must use in this program.
void max(int *a, int *b, int *c, int *d, int *result);
void min(int *a, int *b, int *c, int *d, int *result);
void mul(int *a, int *b, int *c, int *d, int *result);
The functions have the following meaning:
max
finds the max value of a,b,c,d and stores the largest value in result.
min
finds the min value of a,b,c,d and stores the largest value in result.
mul
multiplies a * b * c and divides by d. Stores that value in result.
Below is an example input/output. This input will be read in via the keyboard (use scanf).
input
output (note that user input is shown in bold)
1 2 3 4
Enter the 4 numbers: 1 2 3 4
The max is 4. The min is 1. (a * b * c) / d = 1
100 3 201 103
Enter the 4 numbers: 100 3 201 103
The max is 201. The min is 3. (a * b * c) / d = 585
Your output MUST match exactly the output below for the input from above. Your program must compile, failure to do so will result in 0 points. */

C :: Function To Find Starting Point For Recursive
Mar 6, 2015I am trying to create a function to find the entry point of my map.But my program does not seem to be working correctly. I am trying to place a dot there because I will have to use recursion to fill up the whole map. But I'm not asking for the answer. I just need writing a function to locate the starting row for the first column of the maze (first non zero element). My code seems to have a bug in it when I try and call my function FindEntry. What I am trying to do is read in column by column until I can find the starting point and then place a dot there with ASCII character 249. This is my code so far:
Code:
#include<stdio.h>
#include<Windows.h>
#define HEIGHT 21
#define WIDTH 78

If you try and run it, it will give you a bug. But if you comment out the FindEntry function in the main it will work and look like this:
C :: Function To Generate A Number - How To Find Same Digits
Nov 15, 2014I use rand function to generate a number which consists of 3-5 digits(e.134,1435,73463..). The user decides whether he wants a 3 digit,4 digit or 5 digit number.After that,the user tries to guess the number.Its like mastermind game.The user will enter a number (with the same amount of digits) and the program will calculate how many digits from the secret number he has found and also how many digits he has found in the correct position(e.if the generatir produces the number 32541 and the user tries the number 49581 the program should tell him that he found 3 digits (5,1,4) and 2 digits in the correct position(5,1)) so that after some tries he finds the secret number.My problem is with the functions so that i can compare the digit of each number,find the amount of same digits and the amount of digits in same position.

May 18, 2013I am supposed to write a recursive function which find the partition of a number n ,, for example if n=3 , it should print 1 1 1 , 1 2 , 3
I wrote the program but i am getting the two partition 1 2 and 2 1 which are the same ,, how can i avoid that ?
this is the code :
void PrintPartition( int n , int A[] , int j ) {

C++ :: Find And Replace Function For Text Editor
Jan 3, 2013I'm building a find and replace function for my text editor I'm building the function without support from the algorithm header.
The function is written like: doc.find_replace("Word_to_be_replaced", "The_word_that_is_replacing"); I find this very easy to understand replace this, with this.
find_replace will both have char * as their arguments.
The problem I'm having right now if I replace a bigger word for a smaller word how do I delete the extra characters from memory.
So if I replace "Goodbye" with "Hello" how do I delete the last two characters? So I don't print garbage code.
