But I get these error:

No constructor could take the source type, or constructor overload resolution was ambiguous
Error executing cl.exe.
i am writing this bank accounts program using structures. i haven't implemented the function before that i want to check if the data is being read and printed. When i build and run the program in visual studio it gives me the following error. "No constructor could take the source type, or constructor overload resolution was ambiguous". Now whats wrong in this program?
/* Bank Accounts Program */ #include <iostream> #include <string> #include <fstream> #include <cstdlib>//needed to use system() function using namespace std; const int MAX_NUM = 50; struct Name{
I made a resize function for my dynamic array template class that goes as follows. Note that the private member variables are T* arr, unsigned used, and unsigned cap.
template <class T> void darray<T>::resize(unsigned size) { if (size > cap) { T* temp_arr = new T[size];
[Code] ....
Whenever I use this function to increase the size of the array, it will work the first time I need to use it, but after that, Visual Studios will trigger a breakpoint at line 14, and if I continue past the breaks, I eventually get _CrtIsValidHeapPointer(pUserData) assertion failure.
Suppose I wished to reallocate memory (resize) an array of pointers. Why does the following not work?(The program runs, yet yields a faulty segmentation error message. Why?):
I was going through a code where i found the definition of int array[63] in one of the source files. But i also found the declaration as extern int array[66] in another source file. This is clearly wrong, but my doubt is how the compiler compiled it. It should have thrown error. In case if it compiles then what will be the behavior of the system? Will it be normal or some undefined behavior?
I'm having some problems with changing an array of numbers of type char to type int. Every time i try to sum 2 array indexed values it returns some letter or symbol. Also, if i change the type of the array in the functions the compiler gives me an error message. I would also like to add that the problem requires that the first two arrays be char so each individual number gets assigned to a different value.
My current code is:
Code: #include <iostream> void input(char a[], char b[], int& size_a, int& size_b); void convert(char a[], int size); void reverse(char a[], int size); void add(char a[], char b[], int c[], int size); int main()
im trying to write a source code that find the smallest, largest and average of numbers in array. the code runs fine, but it is not giving the highest number and the the average should include only four number excluding highest and smallest number from the array.
void OlympicJudging() // Olympic Judging { int numbers [6]; double average, sum = 0; int temp; for(int i = 0; i < 6; i++){ cout << "Please type a value for scores: "; cin >> numbers[i];
I am making a tictactoe program that requires me to have a 3 by 3 two dimensional array of integers, in which the constructor should initialize the empty board to all zeroes. The program complies, but it keeps outputting garbage values and i'm not entirely sure why, My print function isn't complete yet, since I want to print out the array in a tic tac toe format, but i'm more concerned with why it's printing garbage values, here is my code:
I can't seem to remember everything I should about constructors. I'm looking for a way to create an array of structs, using a constructor. My code should explain.
struct myStruct { private: int structInt1, structInt2;
I want to pass an array to a constructor, but only the first value is passed--the rest looks like garbage. Here's a simplified version of what I'm working on:
#include <iostream> class board { public: int state[64]; board(int arr[])
[Code] ....
Why this doesn't work and how to properly pass an array? Notes: I don't want to copy the array. Also, I'm using MSVC++ 2010 Express.
I am trying to re-size a bitmap image for a class.They gave us two options to use to do the program with: an array or move the file position indicator. I want to use the file option. All the bitmap header info is checking out. The file after being re-sized should be 822 bytes but it is 1.6 KiB and the image is distorted.
Code:
#include <stdint.h> /** * Common Data Types * * The data types in this section are essentially aliases for C/C++ * primitive data types.
I am currently practicing designing classes. In one exercise, I am trying to store 15 words in an array, and randomly print one (using the rand() functions and seeding it with crime. I have a header file, a respective .cpp file, and a main .cpp file. When I try to compile the code using g++ GuessWord.cpp UseGuessWord.cpp -o UseGuessWord, I get the following error in my constructor: expected primary-expression before ‘{’ token
One can initialize a dynamically created array in the following way:
unsigned int * vec; // ... do something to vec double * a = (double *) malloc(4*sizeof(double)); a = (double[3]){(double[3]){0.0,10.0,20.0}[vec[0]],
[Code] ....
While there is no compilation error for the first assignment, the memory a is pointing to seems to change, surprisingly to me. This seems to solve the problem though:
memcpy(a, (double[3]){(double[3]){0.0,10.0,20.0}[vec[0]], (double[3]){1.0,2.0,3.0}[vec[1]], (double[6]){-2.0,-1.0,0.0,1.0,2.0,3.0}[vec[2]] }, 3*sizeof(double)); // NO C COMPILER ERROR
What does the first assignment do and why does it cause memory to change later in the program?
I know everything works except my copy constructor! There are no errors. The program crashes when it goes to access the copy constructor. why the copy constructor isn't working?
#ifdef _MSC_VER #define _CRT_SECURE_NO_WARNINGS #endif #include <cstring> // access to C str functions #include "String.h" // access String class using namespace std; String::String( int size )// default constructor
Need a C++ constructor to initialize each members of an array. how to give value for for each elements of an array declared as a class object according to the users input.
I am making a tic tac toe program in which they are asking me to have a 3x3 2 dimensional array of integers and have the constructor initialize the empty board to all zeros. They also want me to place a 1 or 2 in each empty board space denoting the place where player 1 or player 2 would move The problem I'm having is, my code initializes the board to all zeros for each element of the array, and prints it out just fine, but I can't figure out how to re-initialize the values in the array to show where each player moves on the board... I was thinking about having a default constructor that has each value set to zero, and then use a setGame function that can change the values on the board to one or two depending on where the player moves....but I don't know if that's possible.....
When I use vectory.push_back(obj), if the length is out of reserved bound, it will deallocate the whole vector and reallocate a big piece of memory. From my understanding I think c++ only allocates 1 more place for the new obj. This is quite inefficient. Is there a way to set the step length whenever the size is out of bound? e.g. 50 more spaces.
When I try to resize my form, every time i try to resize it while running, the window blinks between original size and the new size it was given, when i release the mouse it either stay in its new size or shrinks back to its original size, What makes it return to its original size, maybe its something with the form_Resize function..
