I want to be able to keep on adding a row to my datagrid every time i click a button, the row will hold the text of the text box and the combobox in its individual cells, is there a way to do this without inserting a ridiculous amount of code?
I need to input values for two arrays and then add the two with all of it being print visible. I have this so far but can not figure out how to add the two arrays.
#include <iostream> using namespace std; int main () { { int const ROWS = 3; int const COLUMNS = 3; int square[ROWS][COLUMNS];
You will have two file streams: an input file stream for the file to be normalized and an output file stream that contains the normalized file. You should issue an error message and exit the program if either file cannot be opened. Your program should prompt the user for the filename of the file to be normalized (the input file). The output filename should be the input filename with ".normal" added to it. For example, if the input file is "data.txt", the output file name will be "data.txt.normal".
Be careful to not leave an extra blank line at the end of your output file.
My question here is how do I rename the file that the user entered to have a ".normal" at the end of it? I was thinking along the lines of having to string names and changing the second string's name and use that as the output file. any examples cause I didn't exactly get that to work.
I need to add thevArr[I] and vArr1[I] and store in vArr2[I] but I cant figure out how to drop the value or replace with a 0 if vArr is bigger than vArr1. IE: 1st number: 123 2nd number: 4567
Ill get something like this: 1 2 3 4 5 6 7 5 7 9 -827349
I'd like to start out by adding an array to a C++ class. I'd like to be able to reference the array using a class object that I create, for example:
Class is Stone.
Stone Bob is an instance of "stone" that I name "Bob".
"Bob.array[1] = "granite";" tells the compiler that the second element in the array (with the first being the zeroth element) is a string containing "granite".
I'll eventually want to extend this to an n x m matrix within the "stone" class that can be referenced as: Bob.matrix[1][3]="lignite";
I tried to make this work using a text again and again last night to no avail. My code is below.
NOTE: Since I am dynamically allocating memory space, I'd like to avoid memory leaks when using this class with dynamically allocated arrays and matrices. Not sure how to do this. Also need some insight into "destructor", and why my simple version reduced to a comment below doesn't seem to please the compiler.
CODE FOLLOWS:
Code: // AINOW.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include <iostream> #include <string> using std:: string; using std:: cout; using std:: endl; using std:: cin;
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 writing a program with two classes, one that contains a card's rank and suit and the other contains pile of these cards. I'm having trouble when it comes to adding a pile to another pile...here's what I have so far:
class Card //Card class declaration { private: int rank; //invoking rank char suit; //invoking suit public: void setCard(int r,char s); //determines card suit/rank
[Code] ....
I understand that I'm calling my pile arrays incorrectly, but I'm not sure why.
I've finally been able to get my coding corrected after doing this for 5 hours and watching numerous tutorials on it... But I now need to create a table. how to create a table with dashed lines like -----------------, both vertical and horizontal.
Another issue I have is that I'm having trouble trying to get a prompt to ask the user how many programs, tests, and quizzes he/she completed with their total points. I got the basic programming done, but need a prompt asking "How many (quizzes, tests, or programs) have you completed?"
Finally, the do-while loop is driving me insane, where I have to set certain values. If it is greater than 2, then I insert formula 1, but if it is less than 2, then I insert formula 2. Whichever way it goes, the total points earned minus the two lowest scores are then calculated into an average.
Code:
#include <iostream> #include <iomanip> #include <string> using namespace std; int main()
[code]....
The whole basis of the program is to calculate the averages of programs, tests, and quizzes done during a semester at a school. The user is asked how many of each category he/she has completed (total points earned and total points possible). All of this is then calculated into a cumulative class average in a table along with points earned and points possible for each category (along with tests and quizzes combined into one average along with individual averages).
I wanted to take the averages of the whole week and output a print statement. I've tired few ways this like assigning "temp" a pointer, or in each if statement assigning temp to a new variable like a, b , c etc. Then adding them all up at the end and dividing by 7. My issue is I am unclear how to store the number typed for each if statement while the program is running, then have it compute the simple equation. The code in question is below:
The code is supposed to display the total and averages of the data as well, but cuts off due to an error in the code. The code should also:
1)Print checks for all employees, one per page, sorted by lastname. The first check number, 100, is to be read from a company data file (see requirement 4). The border of each check is important and should not be omitted.
2)Convert the net pay to a text string for each check printed.
3)Print a reference code on each check. The reference code is obtained by combining the first letter of the lastname with all the consonants remaining after removing all vowels (a,e,i,o,u).
4)Use the same employee data found in assignment 2. Use the following company data, obtained from a text file,
Output I'm expecting: Program to display totals and averages (worked before I turned everything into an array), now exits with error before totals/averages are displayed. Program also writes up a report.txt file that also writes this information into it, as well as using a quicksort to organize the names alphabetically, and print paychecks (all of the #BORDER, #HEADER1-8, #STUB, etc). In that check a reference code is also generated (teacher gave us code, we just had to modify for our final program as seen here)
Flow of the program: Print headings to label all of the input data we will enter soon under the categories as listed in the heading. Initialize all of our totals (in our array) to value of 0. These will be added in a loop "AddAccumulators" which takes our value for the hours, payrate, and taxes from each employee array structure and adds it to the total array. Program will write this information into the report.txt file with the HEADER line for totals, and should be displaying it in that picture. (Same for averages). After all of the data is calculated, the Reference code, Totals, Averages, and individual employee data is taken and put into printing out a Check Header and Stub.
Write a C++ program to output information for three students. The information stored in your program contains student’s first name, middle name, last name, and test score. The following shows the information for the three students, where test score is in the int type.
John Jacob Smith 78 Mary Jane Weems 82 Dave Joe Dale 61
Your program should declare three named string constants for the three students. Each constant contains the student’s first name, middle name, and last name. You may use three int variables to hold values for the three test scores. The first name, middle name, and last name of a student are then extracted using the substr() function shown in class. Your program should also compute the average (in floating-point number format) for the three test scores. The average score computed should be printed to the screen with 2 digits displayed after the decimal point.
The following shows the output from the program. Note that all the output is left-justified with 15 character positions reserved for each.
first name middlename lastname testscore average John Jacob Smith 78 73.67 Mary Jane Weems 82 73.67 Dave Joe Dale 61 73.67
I have a project that I am working on and I have gotten stuck. I am getting a couple errors and would like to see how I can complete the program. Not very long of a program at that. My instructions are:
Write a program to calculate averages. Create a method named ReadData that will load a two dimensional array, named scoresArray, with the following data from a file:
Create a method named DisplayAverages that will display the emplyee number (number starting 1324, 4356 etc) and the average of the three test grades. DisplayAverages will have one argument, the scoresArray. Your output should closely resemble the following.
Round averages to one decimal place. Passing arguments is important for this program. No global variables are allowed, except for the streamReader and the streamWriter. The scoresArray must be declared in Main and passed as an argument to the methods ReadData and DisplayAverages.
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using LibUtil; using System.IO; using System.Text.RegularExpressions;
[Code] ....
When I run the following just to see where I am getting I get the following error:
UsersJoeDocumentsVisual Studio 2013ProjectsCIS110Program12Program12Prog ram12Dat.txt was opened Unhandled Exception: System.IndexOutOfRangeException: Index was outside the boun ds of the array. at Program12.Program.ReadData(Double[,] scoresArray) in c:UsersJoeDocument sVisual Studio 2013ProjectsCIS110Program12Program12Program.cs:line 66 at Program12.Program.Main() in c:UsersJoeDocumentsVisual Studio 2013Proj ectsCIS110Program12Program12Program.cs:line 24 Press any key to continue . . .
What am I missing here? I believe I have passed the arguments properly, but I am unable to declair the array within the bounds of the array?
I was required to write a program that takes a baseball players statistics and displays there averages. I was required to make 3 function in the file to perform this tasks. my problem I am having a division problem in the SLG function. My compiler does not require the system ("PAUSE"); command.
OUTPUT The player's batting average is: 0.347 The player's on-base percentage is: 0.375 The player's slugging percentage is: (test)AB = 101 (test)Tot Base = 58 0.000
Code: /* Batting Average Program file: batavg1CPP.cpp Glossary of abbreviations: BA = batting average PA = plate appearances H = hits BB = bases on balls (walks)
how to make the it all work later...but in the mean time how can i get this to display this? Note it has to be made using as a console program. The "Description" and "Cost/ib" collums will be referenced through use of a header file. all else is done by user input and calculations.
I'm having trouble trying to get my loop program to display multiples of 4 in rows and columns. My objective is to print multiples of 4 that are less than 100 in a 4 by 4 format.
So far when I write the code I get 4 8 12 16 20 .... 96 all on the same line.
This is what I expect the code to look like if done correctly.
I want to swap the value of two rows in matrix among themselves, the index of rows are user defined.
void swapRows(int matrix[M][N], int m, int n, unsigned short R1, unsigned short R2) { for (int i=0; i<m; i++) { for (int j=0; j<n; j++) { //dunno what to put in here
Code: int a[6]={1,3,5,8,10,12}; int b[3]={3,5,9}; int c[6]={0}; if a is equal to ANY of the data in b, then c= a*2 if a isn't equal to any of the data in b, then c=a.
Here is the answer I want
Code: c[6]={1,6,10,8,10,12}
I tried using two for loop, but it isn't correct.....
Code: int a[6]={1,3,5,8,10,12}; int b[3]={3,5,9}; int c[6]={0};
i want to print Largest number from any 5 rows.Th number printed should be any one of the largest in the five rows of 2d arrays.I have created code for largest number in each row but how to pick and print them randomly?.
Code:
#include<conio.h> main( ) { int a,b,c,d,e,x; int arr[] = {a,b,c,d,e}; int Matrix[5][5] ={ /*Initializing array*/ 2,4,3,5,9, 6,8,2,2,10,
I am trying to write a program that prints a 2d array to the screen and then compares each row and column to see if there is any pairs of letters. basically something that looks like this:
--------------------------- V T A Y U C B D F W Q Q C R D A L Y M F G O A S S D T I
Number of horizontal pairs: 2 Number of vertical pairs: 3 ---------------------------
so far this is my code below, but i dont know how to approach the comparisons
Code:
#include<stdio.h> #include<stdlib.h> #include<time.h> int main( void )
How i draw such a thing in .TXT file using file handling. This output must be in columns and rows and in well arranged form.
No. Name Roll No. Physic Math Compuer Science Islamiyat Pak Studies Average Grade 1 Student Name 12345 50 60 70 76 90 81 A 2 Student Name 12345 55 52 50 80 58 55 C 3 Student Name 12345 85 66 90 88 77 75 B 4 Student Name 12345 40 70 91 45 56 85 A 5 Student Name 12345 30 80 80 55 93 45 D
Here's my code for adding the rows and columns. My problem is that my program displays an incorrect output.
main() { int a[20][20],r,c,y,x,sum=0,rn,cn,cs=0,rs=0; cout<<"Enter number of columns : "; cin>>cn;
[Code] .....
This should be the output Enter number of columns: 4 Enter number of rows: 3 Enter twelve numbers: 9 2 3 4 2 3 1 2 5 6 7 8
The numbers are: 9234 2312 5678 Sum of number 1 column is: 16 Sum of number 2 column is: 11 Sum of number 3 column is: 11 Sum of number 4 column is: 14 Sum of number 1 row is: 18 Sum of number 2 row is: 8 Sum of number 3 row is: 26
