I have a program that gives the user the option to create an employee ID, name, address and so on. It also has the option to search employee by employee ID.
What I want to know is how to add and replace employee info. For example employee changes address. Also how to delete employee information from text file.
Here's my code:
//This program uses file input and output for an employee information system.
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
int main(){
ifstream inFile; //declare ifstream as inFile and ofstream as outFile
ofstream outFile;
How to search for a word in a text file and replace it with a new one. Such as employee address, or first name, etc.
Here's my code:
#include <iostream> #include <string> #include <fstream> using namespace std; int main(){ ifstream inFile; //declare ifstream as inFile and ofstream as outFile
[Code] ....
It is under choice 3, most of my program runs correctly but I am just stuck at this part.
I'm trying to make a program that you input your login info and it writes that info to a text file. Then, later on once I get my problem fixed, the program will read the info to the user. my code is as follows(the input part is a bit lengthy):
I'm building a find and replace function for my text editor I'm building the function without support from the algorithm header.
The function is written like: doc.find_replace("Word_to_be_replaced", "The_word_that_is_replacing"); I find this very easy to understand replace this, with this.
find_replace will both have char * as their arguments.
The problem I'm having right now if I replace a bigger word for a smaller word how do I delete the extra characters from memory.
So if I replace "Goodbye" with "Hello" how do I delete the last two characters? So I don't print garbage code.
I'm undertaking a project at the moment which requires me to hook into a custom c++ application from a Java applet via JNI. The c++ application needs to communicate with MS Word and potentially other office programmes in order to highlight text and offer find/replace functionality programatically. The idea is that when the applet is launched, it will communicate with the C++ methods to hook into an open MS Word document and highlight all words that start with the letter 't' for example.
I'm concentrating on the C++ side of things first . Even some basic access to an open word document would give me a great start!
I'm a beginner at programming and I'm not sure how to read in information from a text file. What I want to do is take a text file which contains around 20 rows and 3 columns of numbers, and put these into an array which can then be used for performing calculations. How do I do this? Would I need to declare the size of the array beforehand? When accessing my file, do I include the full address?
The relevant part is lines 29-33:
Code: #include <stdio.h> #include <stdlib.h> #include <math.h> /* this is a simpllified code using BEM equations */ main()
My text file have 220 663 lines and 858 995 characters (I used Linux commands : wc to count them. If I use array to store data, I think it's too large array. But if use fstream, I dont know to access each element in stream to compare and replace. I dont know How many labels such as: A1, C- A1, AM- MNR... which I have to replace.
I'm having trouble in getting my program to read from a file and put all the proper data into its proper class variables. I have a class (called Champion) that has string variable for a name and a vector of strings for items. I also have a vector of Champion that holds multiple champions. Here's my code:
I have to develop a C program that reads a very complex txt file (output of a calculation code, so full of mixed text and numerical tables), search for a specific table in it and individuate/print or replace a specific value with assigned position in the table.
I have to create a small data base for a shop. One of the functions i am creating is taking a customers ID and scanning that through a text file and to print out the info about that customer. What i am having trouble with is where do i insert the string compare in my program?
//declaring array for input of customer ID int customer_ID [20]; printf("Please enter the customer ID:"); gets( customer_ID ); //users input stored in the array
I'm creating simple console application using Code::Blocks to allow me to pass parameters from other application to replace string within text/registry file before execute the registry merge. Passing parameters to console already success. Now I only have problem with reading file. Example of first line in the registry file is as below.
Windows Registry Editor Version 5.00
However when read into string and output to console using 'cout', it will be show as below with spaces in between.
W i n d o w s R e g i s t r y E d i t o r V e r s i o n 5 . 0 0
The first loop will print out all of numbers in the velocity column. The second while loop is looking for the maximum value in that column. It is supposed to print out the max velocity in the end of the second loop. However, when I build and run the program, it's crashed. I run debugger and received "Segmentation fault" error. When I eliminate the second loop, it run just fine I use Code::Block for text editor.
I've written a function that has to receive a word as parameter, and then has to find the amount of times that word (uppercase & lowercase) occurs in a text file:
For example, if the word "the" is sent as a parameter, the total amount of times the words "the" and "THE" occurs in the text file, has to be calculated.
However, my function is not displaying the correct amount, what is wrong with my function:
int WordCount :: countWords(string wrd) { int counter=0; string temp = "";
I'm trying to make a program that will search for a line in a text file using a non default delimitor at the start of the line. An example line in the text file would be as follows:
F Mary Smyth, 19, United Kingdom
I have been able to use the find function to search for and return the 'F' character but would like it to then display the whole corresponding line. Is this possible with the find function?
I am trying to print a specific line from a textfile
e.g I have a text file called info.txt and inside it contains the id,item name, price, quantity
Code: 1,shirt,100,10 2,pants,50,9 3,pen,20,8
I know how to find a specific word at the line in the file but how do I find and print out the specific line e.g(print out just the entire contents of line 2)?
Code: string temDescription; ofstream fout; int curLine = 0;
I need to transfer the content from the file text.txt to file sort.txt . The data in the text.txt is "struct" (info about people)but the same data needs to be sorted by the name and sent to sort.txt by using a function .
I am looking for a way that I could check the information of a folder and a drive, to show the data size and storage amount (KB, MB, GB). This is so that I can compare the size of a folder to the storage capacity of a disk drive.
I'm trying to open a text file with the name "text.txt", for the purpose of only displaying in the console an specific part of the text file. For example, if I got "This is a test [TEXT] This is the message that should display [/TEXT] this is the end of the file", I want only "This is the message that should display" to be the output, the thing is that I can't imagine anyway of doing that. what I should do?
Your goal is to open this struct of students (the binary file). Once open, the first job is to print out each student. Afterwards, display all students with a gpa of 3.5 and higher. Finally, display all students with the major of Computer Science or Game Programming. Be sure to title each category of items.
He gave us a .cpp file and a .h file that we're suppose to use to run the program. He doesn't want us to change his original code, except we can add the needed code to run his code (i.e. Struct & Main).
My problem is that I get an Abort() crash message in VS2013 when I try to run it. Now, in line 95 of the cpp file if I replace the char* with "", it runs fine showing the GPA with blank entries for the other print parameters. I've read the Binary Files chapter of the Pearson textbook several times and it doesn't have anything to say about working with char pointers.
