I am trying to use SDL to make a movie easter egg. The movie code is
Code:
#include <iostream>
#include <string>
#include "SDL.h"
using namespace std;
int i;
int main(int argc, char* args[]) {
[Code] ....
I am running Dev-C++ on windows 7 and I followed Lazy-foo's tutorial. I get a linker error in the form of
[linker error] undefined reference to 'SDL_Init'
and I get linker errors to everything sdl in the code also. I also get a linker error to winmain@16. This isn't a project but a source file. I am not going to create a project unless it is absolutely necessary.
I tried to do raining screen of Matrix movie. It's written in C language. Executable file for different resolutions and source code is in the link below.
Directions: Write a program that uses the structure named MovieData to store the following information about a movie:
Title Director Year Released Running Time
Include a constructor that allows all four of these member data values to be specified at the time MovieData variable is created. The program should create. The MovieData variable and pass each one in turn to a function that displays the information about the movie in a clearly formatted manner. Pass the MovieData Variables to the display by value.
I am having trouble calculating the median and mode in a program that I am writing. When I run the program, lets say there are 5 students being surveyed. The input is as follows, Student #1 sees 2 movies, student #2 sees 6,student #3 sees 5 movies, student #4 sees 2 movies, and student #5 sees 1 movie. However, for the median, I get 5, because that is at element 2, and thus midway through the count, so the program interprets that number as the median. For the mode, even though 5 is repeated twice, the program displays that there was no mode, or displays "-1" (indicating no mode). Here is my code:
Write a program that can be used to gather statistical data about the number of movies college students see in a month. The program should perform the following steps:
A) Ask the user how many students were surveyed. An array of integers with this many elements then be dynamically allocated.
B)/> Allow the user to enter the number of movies each student saw into the array.
C) Calculate and display the average, median, and mode of the values entered.
Input Validation: Do not accept negative numbers for input.
#include <iostream> #include <iomanip> using namespace std; // Function prototypes double calculateMean(int *, int); double calculateMedian(int *, int); int calculateMode(int *, int);
I have this code it sums the rows now I need it so it would sum all the columns in the output and put it in row 8 of the outcome. How would I go about doing that?
Code:
#include Code: "stdio.h" #include "stdafx.h" int main(void) { int number[8][7]; }
i am using turbo c++ my program is based on maths equations and my final answer is 918 or any 3 digit number only but i don't want 918 to print instead i want only 18 to print. this program gives different output for every different input so i can't just minus 900 from it and get 18. i just want that no matter what 3 digit number is the answer,i just get the 2nd and 3rd digits while printing it and not the first.
the final answer giving equation is:- f=2914-1996 where f is my answer and its 918 but i want it to print as 18 not 918
I want to make a window tgat stays always on top like that of a cybercafe software. A window that cannot be closed, minimised, deactivated, etc... with wxWidgets.
So far I've tried making a frame window with the wxSTAY_ON_TOP flag. It works, but not to perfection because, when i press the windows button, the start menu interferes with the window(and taskbar too). Also, the task manager, how to deactivate it.
how to make a window in C++? I am trying to make a program that has a boot screen but I want it to be in its own window because it will have it's own pictures in it and text inside too. So not in a terminal but inside a external window.
One that fills different char arrays the idea is to use a single char to represent a char such as 255 but if more than it then use a char array of two chars to represent the next char 00 because if only one is needed it would take less disk space than 0,255 as it would in an array.
My goal is to do this all the way up to an array that can hold 255,255,255,255 but only use the more complex array if needed Example: a char of 255 takes much less space than a char array of 4 chars so that instead of 0,0,0,255 it is written to disk as a single char whereas a char array of 200,0,0,1 would be written as a 4 byte char array. use single char to represent values from 0 to 255 use two char array to represent 0,1 to 255,255 three for 0,0,1 to 255,255,255 and four for 0,0,0,1 to 255,255,255,255
Im suppose to make a "poor mans" variation to the Sort function built into unix. The program is suppose to read in a file and sort the contents of the file. So its a variation of the Unix Sort feature. I have remade the readLine function we were provided so that it doesnt use fgets. where to go from here, Not sure on how to make a sort function. Here are the reqirements of the program:
Code:
• Re-implement the readLine() function so that it no longer makes use of fgets(). Instead, process the input on a given line character-by-character.
• Provide code which will create a data structure similar to argv to hold all of the words to be sorted. Use malloc() to ensure that each entry has just the required number of bytes needed to store the words. The final entry in your array should be the NULL pointer.
• Implement a sort() function which will rearrange the words in sorted order. To swap two words in your array, note that only a pair of pointers need to move. The strings themselves, once established, will never move. Heres what i have:
Code:
#include <stdio.h> #include <stdlib.h> #include <string.h> #define MAX_LINES 1000 /* maximum number of reminders */ #define WORD_LENGTH 10 /* max length of reminder message */
I am curious as to what is happening to my pointers and everything once I call malloc to create space for 5 integers to try to make a stack.
Code:
#include <stdio.h> #include <stdlib.h> void add(int * TOP, int * stack); int main() { int *stack = NULL; int *TOP = NULL; stack = (int *)malloc (5 * sizeof(int));
[Code] ....
I am guessing that when I initialize stack to malloc, stack now stores the starting address of where the space is taken out, and also assigns TOP that address too. I get the choice from the user (b) to get the instruction to try to push on the stack. I was told that the if statement in the function checks if the stack has passed the bounds of 5 elements. If not, it assigns the scanned variable and puts it into what TOP is pointing to and increments TOP to the next address. It is not working and am wanting to see where my logic is wrong.
I will post the entire code at the bottom. Its running fine right now but This part in the menu function I need to make as a separate function. My problem is when I make it into a function by itself I have to declare and initialize the grades A,B,C,D,F how can I do that when I can't make them equal 0 because it has to keep track of how many of each letter grade.
Code:
//Count letter grade if(ave >= 90) ++A; else if (ave >= 80) ++B; else if (ave >= 70) ++C; else if (ave >= 60) ++D; }
I'm trying to write a program for a lab, I know how easy it is but cant see to crack it.
I need to make a program using while or for loop.
I must have the user type a number, for an input value an output value but then do it again several times but without it going on forever asking again and again.
I'm making a simple single-player game. Now, assume I've made the game, how would I go about making it available to play on LAN? (I'm not really bothered about making it playable across the world with people not on the same wi-fi)
So, any way that I could get started or any libraries/APIs ....
I'm using Windows 8.1 and I'd like my game to be playable on other Windows OSs (7 and Vista if possible)
i need to write a program that when run makes another exe file . Eg: make a program named 'sxes' and compiled it. When i execute or run sxes a new exe file named 'new01.exe' is created. This new01.exe when executed must input two numbers and add them and print output. I want to write a program same as installer file .
I can't seem to make the STL iterator class work how I need it to.I am implementing a multi list graph and I need to iterate through my STL list of Vertex pointer objects. I keep getting the error:
Error 1 error C2679: binary '=' : no operator found which takes a right-hand operand of type 'std::_List_iterator<_Mylist>' (or there is no acceptable conversion) and the same for != for my terminating condition.
template <typename V, typename E> void Graph<V, E>::InsertEdge(V from, V to, E edge) { list<Vertex<V>*>::iterator iter; for(iter = m_Vertices.begin(); iter != m_Vertices.end(); ++iter)
Well, sort of - my question is, since the destructor has to be virtual in order to be marked final (you get an error otherwise), does this cause virtual function overhead anywhere, or add a vtable?
I would like to know if there is a way to make a function non overloadable. My idea is to keep it private in the class so that it will be impossible to overload the function in a derived class.
But if in the base class (the one that holds the private function) I also have a public or protected function (let's call it plf) to manage the private one (let's call it prf), and in the derived class I create a function with the same name as the private base class function (prf) that calls for the public base class function (plf), I am wondering if there won't be a conflict between both of the same-named (prf) functions?
Assuming the prf function of the derived class is not an overload of the prf function of the base class (because the last one is not visible).
I'm new to c++ So I have a project to make. I need to make a cursor like an arrow that will move when inputs are given. e.g if input is given 500 spaces UP it will move up and so on. it should rotate as well like 45 degrees and so on. how to make this arrow WITHOUT USING GRAPHICS.
