I want to add this piece of code to a project. I have created a vector from values entered by a user. I want to then subtract each value from each other from the beginning to the end. For example if a user enters 10,4,3 the program will subtract the values in that order 10 - 4 - 3 and output 3 as the solution. I figured how to do it with addition but can't get it to output for subtraction.
#include <iostream>
#include <vector>
using namespace std;
I would like to subtract one image from another to get something like "differential picture" (i am not sure whether the name is correct). I've managed to read the FILEHEADER and FILEINFOHEADER of bitmap. I will subtract 24-bit bmp files only. However i can't understand the structure of this file. So far my code looks like this. Any example of at least copying one bmp file to a new one? This example would be useful, because subtracting will be simillar, instead of copying the pixel value i will just put abs(value1-value2) in the output.
Code:
// ConsoleApplication1.cpp : Defines the entry point for the console application. #include "stdafx.h" #include <iostream> #include <fstream> using namespace std; struct BITMAPfileHEADER {
I have some ascii characters in a char variable.ex - char buf[100]="ab*(z&";
So each of the char in that char array will have some hex value.ex- *'s hex value is '2a'.
And I have a long long int variable in which there is a 64 bit hex value.
ex- long long int k=0x0000888888888888;
Now i want to subtract the char buff's hex value in k. How to accomplish it.
That is 0x0000888888888888 - 0x000061622a287a26 = 0x000027265e600e62 (final result in a buffer or a long variable is okay)
Later i want to reverse the result as 26e006e56272.It should be stored in a variable such that i should be able to access each byte from it(ex- '72'(last 2 hex digits))
I have a 2d array where I manage donations and requests for different foods. I output a menu to the user who picks the options to either make a donation, make a request, fulfill a request, or print a status report of all the donations and requests. What I'm having trouble with is the fulfilling requests option. When the user picks fulfill requests that means that the donations are supposed to be subtracted from the requests. For example if there are 10 donations for grains and 15 requests for grains then after picking fulfill request there should be 0 donations for grains and 5 requests for grains but I don't know how to make the program do that since the values are in a 5 row by 2 column array. The five rows correspond to the five foods and the two columns correspond to donations and requests, respectively. Here's my code so far. Just disregard everything but the third case.
Code: #include <stdio.h>int main(){ int foodbank[5][2]= { {0,0}, {0,0},
I have 2 integers, both in 2 seperate classes in 2 seperate files. I have main.cpp, test_01.h, Test_01.cpp, Player.h and Player.cpp. I ahve a function which takes an integer (a) as a parameter (from Test_01.h and Test_01.cpp). a sets another integer (attackPower) from the same class equal to a. The integer (health) in the other class (Player.h and Player.cpp), is then equal to health -= attackPower. But instead of giving me the right answer 75 (health = 100 and a is set to 25 when i call the function) it gives me the answer.
main.cpp
#include <iostream> #include "Test_01.h" #include "Player.h" using namespace std; int main() { Player p; Test_01 t;
[URL] .... This is what I have so far, and it isn't incorrect, but how to improve this or make it more accurate?
// subtracting the area of two circles from a rectangle #include <iostream> using namespace std; int main() { cout << "This program is designed to calculate the area of a rectangle, to exclude the area of 2 circles that have been placed inside of the rectangle." << endl << endl;
I am currently working on a program that uses a class to store integer arrays. I have most of the code done, but I am having trouble on the main.cpp part of my program. The program should display this:
I'm trying to print values from a vector of a struct and I don't really know how to do that. Here is a simple code that I have for now to test how to add data to the vector then attempt to print it out.
#include <iostream> #include <vector> #include <string> #include <deque> #include <fstream> using namespace std; struct Employee//employee data
I have a class that uses std::vector. I push back class objects onto the vector but when I try to cout the data members (with get functions) I get garbage values.
Here is the class:
#ifndef JOBS_H #define JOBS_H #include <iostream> #include <iomanip> #include <vector> #include <string> using namespace std; class Jobs{
[Code] ....
I know I am missing the implementation of several functions but I'm just testing my vector to see if it is working and it isn't. The getBlockValue() function should output 0 for each job. When I push back one object the output is 0. When I push back 2 objects the output is 0. However when I push back 3 objects I get random values. Why is this? I thought vectors were dynamic?
I am writing a program to play rock paper scissors, and I am trying to get a vector to store the result of a given round of play, and output it as a declaration as to who won. I can't figure out how to store the values in the vector properly, and how to use the vector as an argument to output the result of play.
I am trying to seed a vector with 52 values ranging from 1 to 52. I already have the code written to seed the vector bu how to keep from repeating the same values from being seeded. This is for a five card stud game.
#include<iostream> #include<cmath> #include<cstdlib> #include<string> #include<vector> #include<ctime> using namespace std;
Now asking for streams. Calling getAvailableStreams. Giving so many streams: 2, 2 got so many streams: 0
Why am I getting 0 streams when I exist the method? I just had 2 streams in availableStreams while I was inside the method, where have they disappeared?
I'm trying to increment the values in a vector, not the vector size, based on variable input. Basically I have a vector of size 10, and all of its values are initialized at zero. The program counts the frequency of numbers 0-9 in a four digit user input. This is what I have (I want it to work so badly but the compiler says that I'm using a pointer to a function used in arithmetic):
for (int i=0; i < num_slots; ++i) { ++guess_frequency[guess[i]]; }
I just want to know if you can increment values within a vector:
I have a function that rotates a vector 90 degrees. Only problem is, i never get negative values. For some strange reason, no matter what i do, the value of x is positive. And even if the x is negative. Once i put it into direction (struct with 2 values x and y) it turns again to positive. Im using VSC++2013 ultimate. At first direction was SDL_Point, so i thought it was SDL problem, but now it seems its something else.
if (c == '-') { int x = direction.y; x *= -1; int y = direction.x; direction = { x, y }; }
I'm trying to get my program to read a series of comma delimited values from a file into a vector. However, I am unsure how to actually go about doing this. I've posted my best guess below but it's really just a stab in the dark and I always receive a compiler error.
How to output vector contents using the push_back function. My program reads in values just fine, but it does not output anything and I've been stuck on why.
here is my code:
#include <iostream> #include <array> #include <vector> using namespace std; int duplicate( vector < int > &vector1, const int value, const int counter)
I have a cpp app that reads in a number of files and writes revised output. The app doesn't seem to be able to open a file with a ' in the file name, such as,
N,N'-dimethylethylenediamine.mol
This is the function that opens the file :
Code: // opens mol file, reads in rows to string vector and returns vector vector<string> get_mol_file(string& filePath) { vector<string> mol_file; string new_mol_line; // create an input stream and open the mol file ifstream read_mol_input; read_mol_input.open( filePath.c_str() );
[Code] ....
The path to the file is passed as a cpp string and the c version is used to open the file. Do I need to handle this as a special case? It is possible that there could be " as well, parenthesis, etc.
write a c++ program that reads an unknown number of integer values and then print count, sum and average of odd values, even values, positive values, negative values!!
