C/C++ :: Program That Can Read And Edit Structure Arrays
Feb 5, 2015
writing this program where you can search a structure array for existing elements, add new elements to the structure array, and find and display entire elements of the array structure and all.
Right now I am stuck on adding new elements to the structure array.
I am working on a program that will do several mathematical calculation and will store the data into a csv file.The one below is just a prototype version of this.In my program,I will store my csv file as (current-date).csv using time.
With this in mind,I want my program to first check does (current-date).csv already exists.If not,the program runs normally and output all the data into the csv file.
However if (current-date).csv already exists,I want my program to read and edit that particular csv file,by skipping part1 in my code(name,id N etc.) and start with prompting the user for numbers straight-away.
In other words, if (current-date).csv already exists,the user should continue outputting the numbers from where the user last left before last termination instead of outputting the name,date & etc into the csv file again.
Eg: if no=22, continue inputting values from no=23 till terminating the program again and storing the values correctly into the csv file.
I define "Comwords" as a string, but apparently it takes the members as chars, then I can't set strings in a structure equal to the chars.
I see to also be having unknown problems with the ComMAL array and loading it values into another element of the same structure.
How to correct this? I was thinking of casting char elements as strings, but could find no reference in my library book regarding how to do that (lots on casting int's a doubles...)
Code:
int _tmain(int argc, _TCHAR* argv[]) { int comm = 10; int targ = 5; int death; struct AI_WORDS
This is a small program that reads a line from the screen, takes the ASCII values from the entered text, and edits it. Next, the ASCII values are reinterpreted (am i misspelling?) as text, and displayed. However, my final output has (allways?) at least 7 characters, even if you enter only one. I'm also trying to accomplish, that the part of the string which isn't filled, will be printed empty. In spaces.
compiled with -std=c99.
Code: #include <stdio.h> int main(){ int maxsize; printf("How long is your message?
Description: Use functions and structures to simulate storage in a warehouse
*/ #include <cstdlib> #include<iostream> #include<cmath> #include<iomanip> #include<string> using namespace std; struct Bin {std::string name; int Quantity;}; //create a structure for "Bin"

I keep getting a linker error on every function. what am I doing wrong?
There are 7 candidates and 365 votes in total. I need to do this using an array of structures. I need to read from a text file each of the names of the candidate and the number of votes they get. At the end i need to output the winner of the election.
Each candidate gets +1 vote for their number electionCandidate[0] for each one he gets one vote and so on for the rest. 365 voters in total.
I was able to input the name for each Candidate from the text file. Now the problem is putting each vote to the corresponding candidate. Also any vote that is above 7 is a spoilt vote which i am trying to count in the above code. The code compiles but it crashes.
I am using while(!feof) but it seems that its not working or this is not the correct way.
I am trying to use arithmetic on structure members read from separate text files into separate functions. I'm trying to do the math in the main function after calling the other two functions. I'm trying to divide nato_attack by pact_defence.
The warning I'm getting is: both are being used uninitialized in this function.
The goal is to read/write the info in the text files and to use them as any other variable, i.e. add, subtract, etc. in other locations in my code, i.e. functions, modules.
I "borrowed" most of this code from a youtube lesson and modified it for my needs.
Below is the contents of the two text files and my code.
This is for NATO 6 12 4th_mech_div mech div 14 16 7 12 5th_mech_div mech div 10 8 7 12 3rd_mech_div mech div 5 6 6 12 1st_mech_div mech div 4 6 7 12 2nd_mech_div mech div 12 14 7 12 6th_mech_div mech div 8 12 6
This is for Pact 3 10 1st_Guards armor div 12 8 6 10 2nd_Guards armor div 12 9 6 10 3rd_Guards mechanized div 10 9 6
My program is designed to read input from the user and then store that input in a structure variable. Whenever i use the cin.getline() function, it comes up with a semantic issue. Here is the code:
I tried to make the program read from a file text the first name or last name but o cant seem to get it. i tried alot of different ways. how can i get the array of structure code to read form a file?
#include <iostream> #include <fstream> #include <string> #include <cstdlib> using namespace std; const int NUM_STUDENTS = 17; const int NUM_QUIZZES = 10; const int NUM_EXAMS = 5;
I would like to write a complete structure array to a file and read it back, recovering all the data. I have tried the following:
Code:
#include <stdio.h> #include <string.h> #define NUM 256 const char *fname="binary.bin"; typedef struct foo_s { int intA; int intB; char string[20];

//---------------------------------------------------- but the mac field is reading back some random value repeatedly. Why is that? And how do I fix this?
reading and writing 2D arrays I've been trying out a few tutorials using FileStream but I couldn't get any of them to work.
Anyway what I'm trying to do is save the playerArray to a .txt file and then read from that .txt into the fields within the GUI. This is supposed to act as a database.

I'm making a Jeopardy game and when I read text from a file into arrays to set the categories, questions and answers a couple of the strings are not terminating and they are printing that junk box thing at the end.
When I use the debugger and print the problem strings they are showing up as "Thanksgiving21" or "Calvin Klein21" but all the other strings aren't having that problem.
Then for example I will change "line[strlen(line)-1] = '';" to "line[strlen(line)] = '';" and other strings will have that problem but not those stated ones. I'm using line[strlen(line) - 1] = '' to get rid of the newline fgets appends on the end of the strings.
Trying to do a homework assignment for a class and how to read a file into an array. I've looked in our book and on several other forums and cant seem to find any examples of this. Below is the assignment I'm working on. I have a shell of the program that I can get to run, but getting a .txt file to read into an array is something I cant seem to figure out how to do.
Write a program to read N data items into two arrays, X and Y, of size 20. Store the product of the corresponding pairs of elements of X and Y in a third array Z, also of size 20. Print a three column table that displays the arrays X, Y, and Z. Then compute and print the square root of the sum of the items in array Z. Compute and print the average of the values in array Z and print all values above the average of array Z. Determine the smallest value in each array using only one function.
Use the two data files named DATAX.TXT and DATAY.TXT.
You must use functions for the reading of the data, computing the average, printing the three column table and printing the values above average.
// declare child arrays public string[,] childcolor; public string[,] childgeneo; // create dictionaries public Dictionary<string, int> colors = new Dictionary<string, int>(); public string color; // name for dictionary public Dictionary<string, string> geneo = new Dictionary<string, string>();

I'm getting "field' is used like a 'type' error on jw.childcolor which causes other parts to error out.
How do I fix this & why am I getting the error?
I want to convert the dictionaries to arrays to read & write sequentially.

how I can read information from a text file into an array so afterwards I can display the array and it will show the contents of the text file?
the information inside my text files consist of names and numbers like so: "Collins,Bills 80" should I separate the numbers and names into two separate text files one for names and one for numbers?
A company uses two text files: one to store employees' details and another to log their sign in/out time.
The details file - called details.txt" has the following format: ID, Name, Date of Birth, SSN, Department, Position - separated by spaces.
An extract from the file looks like this:
10 alice 4/23/1972 123-45-6789 support assistant 3 bob 6/7/1980 111-12-1134 logistics manager 1 carol 10/2/1963 987-123-1143 admin ceo 2 dave 10/3/1974 902-22-8914 admin cfo 17 erin 6/13/1991 126-83-1942 technology supervisor 15 frank 2/22/1987 303-12-1122 logistics assistant
"timelog.txt" contains daily logs of when employees arrive and leave. It has the following format: ID, Date, Arrival Time, Departure Time - separated by spaces. An extract from the file looks like this:
I have to write a program that searches for specific records using some search parameter, and displays them. Ok first i have to read the data from the files and store them. this is what i have so far....
#include <iostream> //Accesses libaries for console input and output #include <fstream> //Needed to access the fstream object to read files #include <string> //Needed to access the string class #include <cstdlib>
[Code] ....
I know my class and array code is totally wrong i dont know how to store the data for the info is in integer and string form... do i use strings, arrays?
Given a set of different types of paired symbols; determine whether it is balanced or not (the opening and closing version of each type are paired correctly). Any other type of characters may appear in the input will be neglected.
For example: (**(*[*])****) is balanced, also [{}**[]**()]** is balanced. But ((*{*)*}) is unbalanced as well as [()***[]***{*(*)}.
Write a C++ program that requires a string containing and expression as an input from the user and check for balanced bracket pairs using stack data structure.
Here is my code which give me nothing when I run it.
#include <iostream> #include <string> using namespace std; class CustomStack {
Been given an assignment to create a predictive text program. What data structure I should use for this and the steps I should take when I make the program?
