C++ :: Calculate Product Of 4 Vertical Values In Matrix
Jun 1, 2013
I am attempting to create a program which calculates the product of 4 vertical values in the matrix. The numbers are supposed to be randomly generated and the size of the matrix is given through the command window.
However I seem to have either not pointed my matrix through all of my functions correctly, or my logic is off somewhere as I keep getting this output regardless of the size of matrix I put in:
"the location of the highest horizontal line product is: 5 0 and is the number: 0
The overall max value is 4196352 at the above coordinates."
using namespace::std;
//srand(time(0));
int h_line(int**, int, int);
int v_line(int, int,int);
int diagnol_left(int,int,int);
I write this code for Inverse of matrix in C language . But there is error in determinant function that say "can not convert 'float' to 'float(*)[20]' for argument '1' to 'float determinant(float(*)[20])' " ....
/* a program to calculate inverse of matrix (n*n)*/ //actually one of the way to calculate inverse of matrix is : A^(-1) = 1/|A| * C(t) that A is matrix and c(t) is taranahade A
#include <stdio.h>; #include <conio.h>; #include <string.h>; #include <stdlib.h>; const int max=20; int i , j , n , k , size=0 , row , column ; float num , det=0 , inverse_matrix[max][max] , matrix[max][max] , new_mat[max][max] , m_minor[max][max] , m_Transpose[max][max];
I have the following void function devised to assign "+1" or "-1" to each element of a matrix at random. While the function does what I want, when I print the values of the matrix all are set to zero:
#include <vector> #include "aRand.h" #include <iostream> void initConfig(std::vector<std::vector<int> > premat, int nL, int nN) { int * pnRand; pnRand = 0;
[Code]...
The function pnRand_plus returns a pointer to an array of random numbers from 1 to 100, with seed time(NULL) + i. The values printed in main are zero, despite the values printed during the function run are fine (-1s and +1s).
I have an array matrix called tmat,,and i know that in every row of tmax there are values which repeat two times...and am writing a code to extract the values WHICH DOES NOT REPEAT into another matrix called tcopy...the codes compiles fine...and it writes nicely to file...but without the desired result...
One last question...how can i get the array tcopy written to file in the form 5x3...and not all the figures in line one after the other? i mean i wish to see the matrix like a matrix on file..not like a list of numbers....
Code: #include <iostream> #include <fstream> #include <vector> using namespace std; const int R = 5; const int C = 5;
Ok I'm trying to create matrix of data that I can add values to based on a reading that I will get from a DVM. I'm using a 3d vector to do this. I need to keep track of the serial number, the day and within day I need to take two readings at different temps, this will continue for 7 days.
The rows of my 3d vector will be the days, the colums will be the serial numbers the depth will be the reading at the different temps.
What I need to do is compare the first element (days) and when it is greater then or equal to 4 I will perform calculations of the readings. So all I want to do is compare the first element of the vector, How do I do this?
gore calculates x^(2*i)-3 and dole is for (2+i)! for input x=1 and n=1 i get -2.0 output which is the value of x^(2*i)-3 the (2+i)! part gets ignored for some reason, for any other input i tried the output is 0 ....
i wrote following code to calculate average of the values entered to the array.After displaying the output following error was displayed.
"Run-Time Check Failure #2 - Stack around the variable 'marks' was corrupted.
A buffer overrun has occurred in q 3 410005111.exe which has corrupted the program's internal state. Press Break to debug the program or Continue to terminate the program. "
//Average mark of student 1 cout<<"Avarage mark of the student 1 :"<<(marks[0][0]+marks[1][0]+marks[2][0]+marks[3][0]); cout<<endl;
I am really desperate on trying to make my code work. The code is to find the eigen values of any given matrix of dimension NxN. The input can be the diagonal of any NxN matrix alongwith its subdiagonal. The code works fine for N~350 or so but when i go beyond that these errors appear.
First-chance exception at 0x00425ea4 in divide.exe: 0xC0000005: Access violation writing location 0x01141000. Unhandled exception at 0x00425ea4 in divide.exe: 0xC0000005: Access violation writing location 0x01141000.
But as i have never declared any variable statically and when i dynamically allocating memory with variables it should work like it does for smaller N values.
I'm trying to calculate the number of distinct values entered into an array. If i enter the followings "3,4,5,6,7,7,6,e (anything that's not a number)" . I get a total of 7 but in reality it should be a 5.
Code:
#include <stdio.h> //---------function to find the distinct values---- int find_distinct(int list[], int size) { int i, j,size2, distinct = 0; for(i = 0; i < size; i++)
I have this code that im stuck on what i need to do is Extend the code such that when it starts the user is asked to input values to specify each of the three ranges before moving on to accept and tally the main values how do i do that Using a for loop to input and output array values Also calculate the average
*/ #include <stdio.h> int main(void) { /* Declare an array of integers */ int Grades[5]; int nCount; int nTotal = 0; /* Declare and initialise the value */ float fAverage;
I am having trouble with calculating the volume of a cone
Assignment: Using the knowledge you already have, create, build, run, and correct if necessary a program that will calculate the volume of a cone. Insert into your code values for diameter of the base and the height. Use variables, constants, literals, and mathematics as necessary.
The formula for the volume is:
1/3 π x Radius2 x Height
Hint: you will need to add to your program two lines where appropriate:
#include <cmath> const double PI = 2*acos(0.0);
Here is my current code:
#include <iostream> using namespace std; int main () { //diameter of the base float diameter = 3;
So I have to make a program that allows the user to enter both positive and negative numbers and the program is suppose to calculate the sum of only the positive values while ignoring the negative values. Also it is to be a sentinel-controlled loop with a number ending the set of values.
Scaling the yaxis on my histogram for one of my class projects. I've gotten mostly everything but stuck on scaling. I'm pretty sure it's something simple to do, but I'm having trouble, and I've tried everything to my knowledge to get it scaled from 0.1 - 1, like this:
Here is my code:
#include<stdio.h> //include all preprocessor directives #include<Windows.h> int main(void) { int MAX = 0; //initialize and declare variables int allcounts [10] = {0}; //store an array of integers for int yaxis, xaxis = 0;
[Code] ....
I'm close, but every time I try and change my y axis in the for loop from 1 going down to 0.1, it doesn't give me a right output.
I'm trying to find vertical paths of length n through a 2D grid of numbers. Paths may connect orthogonally or diagonally. An example grid and an example possible path looks like this:
A example possible path of length n = 3 is running from (3,2) to (3,4) - All 1s ...An example of n = 4 is the run of 3s (1,1) (0,2) (0,3), (0,4)
What is an efficient algorithm for solving this kind of problem? I would like to solve (ideally) millions of grids, giving a list for each grid of all possible paths of length for n = 3-6.
I have an MDI MFC application which has a menu at the top. Nothing particularly unusual about that, but for some reason my application seems to have a vertical spacing about 30%-40% bigger than "normal" on the drop down menus (when compared with Visual Studio itself).
I've looked thru the options for CMenu, CMFCMenuBar, CMFCVisualManager, but can't seem to find anything to explain why my menu has such a large vertical spacing between options, nor how to change it.
im trying to code a simple list box for my self made GUI but i seem to be stuck at the scroll bar. I already finished with the calculation for the scroll bar size but how I could calculate it's current vertical position depending on the current item on top of the list box.
My current code looks like this
ListBox struct: struct MenuListBox { int PosX; int PosY; int Width; int ItemsVisible; //Items visible at the same time int CurrentItem;
How to fix this when i run the program and enter my name then output my name in vertical position using the for loop and press enter the program do not stop
In a MDI-app with some toolbars and statusbar I created also a controlbar which can be docked to the left side. My problem now: how do I get the exact height of the controlbar?
In CalcDynamicLayout I set the height for the docked state to the height of the mainframe. This value is too big, but it will work basically.
But how can I get the exact height of the controlbar?
So I need to make a program that reads distance and number of days of a person that is buying a ticket. If distance is greater than 1,000 kilometers AND the person stays more than 7 days, the discount is 30% of the ticket. The cost per kilometer is $1300. Print the ticket with discount.
I used variable distance as float because it will be multiplied with 0.3 for the discount... not sure if I'm right on that.
Code: #include <iostream> #include <conio.h> using namespace std; int main() { float distance; int days;
[Code] .....
I tried another way but haven't done it in code...
ask for distance ask for days
Ticket= (Dist x 2 x $1300) If (dist>1000) && (days>7)
