C++ :: Make A Function Integrate To Work With Other Functions Given
Mar 10, 2013
We have to make a function integrate to work with the other functions given. I had it working before but I would only get all -4 as my answers but only the first one should be -4. what should more or less be put in my integrate function?
So I need to make a main function have no if/for/etc. statements so I need to move it to another function and call it in main. The problem is that it's a command line argument function so I'm confused on how it works. Here's an example:
Code:
#include <stdio.h> int main(int argc, char* argv[]) { printf("The program name %s", argv[0]); if (argc == 2) { printf("Argument supplied is %s", argv[1]); } else if (argc > 2) { printf("Too many arguments");} else { printf("One argument");} }
How can i make this into two functions with main only declaring variables and calling other functions?
I'm having with header files, specifically to do with the string data type. The objects work perfectly when I put them inside the .cpp but when I set it to include the exact same code in a .h, I get a string of error messages.
class Topic { private: string NInfo, SInfo, EInfo, WInfo, Name ; bool Quest ;
The program i am trying to make is for practice of using switch. the idea is the user enters a number and the program will print a day of the week corresponding to said number.
the statement is not complete with all cases yet, but i dont want to write all of it until i am sure of it being correct.
errors when compiling (gcc) are as follows
1 warning and 3 errors generated. Robins-MacBook-Air:array2 RDenton$ gcc array2.c array2.c:26:9: warning: format string is not a string literal (potentially insecure) [-Wformat-security] printf(a[uservalue]);
I made a function as my project and name search/lastname search functions are not working and giving a runtime error. I can't really see the mistake. So what's wrong it?
Also ID and Mark search system has some bugs with them, whenever you search for an ID it also brings mark = 0, also if you search for Mark, it will bring ID = 0.
Exact error is; Unhandled exception at 0x6583f5cf in proje10.exe: 0xC0000005: Access violation writing location 0x00eb0000.
I have a WPF DataGrid with DataGridTemplateColumns, when I select rows and use Ctrl+C, and then in Excel or any document Ctrl+V, no data is pasted. If I change columns to DataGridTextColumn then copy and paste works fine. What can I do to make work copy & paste with DataGridTemplateColumn? Also when I set ClipboardContentBinding="{Binding FirstName}" for the template column, Null Refrence exception is thrown.
I've got a calendar in Form 1 in my code, and buttons in Form2. I need these buttons to send codes for this calendar in Form1. How may I make these work? My friend told me to do a function as a new class, but I'm not sure how can I do this.
The doubt is. I have a test_xpm function and I need to call this char array but this is so many pointers that I can't even figure out where I'm pointed to (?)
Code: int test_xpm(unsigned short xi, unsigned short yi, char *xpm[])
I tried something like read_xpm(xi, yi, *xpm[0]); but I'm guessing I need to index that array and run all those chars in order to show them.
i need a function that will work for both dynamic and static implementations of a function to get the transverse of a matrix. so far, i have this
Code:
matrix transpose(matrix m) { int row, col; row = m.com_dim; col= m.row_dim; }
[code]....
this works well with my static implementation, but when i try it in dynamic it gives me errors. the function has to be the same for both dynamic and static implementation
You can check it here: [URL] The output is correct, but in my machine with C++11, MinGW 4.8 (64 bit in a 64bit-Windows8), the output is incorrect. Why?
If you want more specific info, the problem is that I use input, I think. I use std::getline(std::cin, some_string).
i am facing some problem with qsort() function it work well if the last element of array is larger then the 2nd last element. But in case if last element of array is smaller then the 2nd last it will sort the whole array and remains the last as it is. For example
Code: int group_id_local[max_j]={2,1,4,5};// it work fine, output should be {1,2,4,5} but if i have this one
int group_id_local[max_j]={2,1,4,3}; // output should be {1,2,4,3} /* COMPARE FUNCTION FOR USING QSORT()*/ int cmpfunc (const void* a, const void* b) { if (*(int *)a < *(int *)b) return -1; if (*(int *)a > *(int *)b) return 1; return 0;
I have to do a BST project for school and I am almost there. Here is the code:
BINARY_SEARCH_TREE.cpp #include "stdafx.h" #include "genBST.h" #include <iostream> using namespace std;
[Code].....
When I run the program, it compiles correctly but does not give any output. I'm not sure what else to do. I've tried changing up the code in nodeCount(), leafCount(), NodeCount(), and LeafCount(). I've tried adding a count variable to both nodeCount() and leafCount() but that didn't work. If I fiddle with the functions, I get a whole mess of errors. Currently, the code is stable but just won't output what I want it to.
I'm having trouble with getting a sine function to work. All variables are defined earlier in the same section. I have the code in a button (where I figured it would go) but I get the following error:
WindowsFormsApplication2.Math does not contain a definition for 'Sin'
For reference, I am using Microsoft Visual Studio Express 2013, and am coding a Windows Forms Application.
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text;
[Code] ....
I've tried other functions as well (abs, sqrt, etc.) to no avail, as Math only seems to pop up with two options: Equals and ReferenceEquals.
void Quicksort(int info[],int left,int right){ int pivot = left + (right - left)/2;//it is the middle (will change sometimes but will end up in the middle int temp;
while(left<=right){ while(info[left] < pivot){
[Code] ....
This is my quicksort function. I have tried a lot of things but I am trying to get it to work to sort all the details I have stored in an array by there age. This is how I have entered the data.
void DataEntry(Details info[],int size){ int x; int i; i=0; cout << "How Many Entries Would You Like to add";
This function should delete each element in the list which is the same as this one typed by user. There are no errors, but function doesn't work. It deletes something, but not this element which should.
I wrote a program with function my own function which count the digits of entered number. The problem is whatever i type it shows 0 digits.Why is that?
Code: #include <iostream> using namespace std; int cikCipari (int skaitlis, int cipars); int main()
Ok so I am working on a game and I'm in the process of developing my Player class. Anyways, what I have is a keyboard function that is called in my main function to make a shape move.
void myKeyboardFunction(unsigned char key, int x, int y) { switch ( key ) {
[Code].....
But when I try to call it, trying to copy my previous method,
glutKeyboardFunc(Player1.playerControls);
I get an error
error C3867: 'Player::playerControls': function call missing argument list; use '&Player::playerControls' to create a pointer to member
I get an error saying it can't convert parameters. I would just like to understand why the arguments become a problem when I make the function a member of my class, when the first method I used is so easy.
We are making a program--but every time we input a value for scanf, the following for loop does not work and the program quits without displaying the for loop's function. We are not getting any errors.
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 */
