I just recently started looking into C++ programming so I don't know much.
I was wondering is it possible to write a program to pick a random name from a list of names, which are in a .txt file? or if I could ask the user to input the list of names and then let the program pick a random name?
I got this code here id like for it to pick up a random word from a text file and use it as the nick in this line
Code:
SetNick(GetRandomString(10));
how could i do it heres the full code for the client
Code: using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using FluorineFx;
using FluorineFx.Messaging.Adapter;

What I'm trying to do is to have the program pick random people for different jobs. The user enters the number of people, then, enters both jobs and the people's names. I need the program to pick random people, but randomly pick again if the person has already been picked, so, no repeats. I have the program picking random people, but I can't get it to not pick the person again. I'll run it and there will be no errors, but it's almost like Xcode completely bi-passes the for/if to check if it's picked the person already.
Below is the code.
#include <iostream>
#include <math.h>
using namespace std;
int main() {
int runagain=0, correctnames=0, versiondesciosion=0, correctjobs=0;//vars that make descisions for running again

Dont look at the "fun" version for the switch statement. It's not ready yet, I'm just having trouble with the random thing.
Basically we have this 7 bit binary code, and i would like to pick out 3 numbers randomly from it, how do we do that ?
for example 1011101
int Num[7];
for(int i=6; i>=0 ; i--)
{Num[i] = binary % 2;
binary = binary/10;}
I have almost a hundred names in a text file that I want to convert to email addresses and save to another file. I seem to have it working, but it doesn't print the full names in the email prefix. The output I'm looking for is Doe_John@livebrandm, but I'm only getting D_J@livebrandm. I'm not sure what I should specifically be reading up on that applies to this directly.
Code:
#include <stdio.h>
#include <stdlib.h>
int main(void)
{
FILE *fpin=fopen("namesIN.txt", "r");
FILE *fpout=fopen("emailOUT.txt", "a");
char first[20],last[20],inbuff[1500];

i have a vector of stores. i would like to delete the specified choice(store) from the list. Here is what i have but my erase statement is wrong and wont compile.
void Store::deleteSpecifiedStoreFromList(string choice) {
for (int i = 0; i < this->stores.size(); i++) {
if(this->stores[i].getStoreNames() == choice) {
this->stores.erase( std::remove_if( this->stores.begin(), this->stores.end(), choice ), this->stores.end() );
}
}
}
Creating a C program that can pick words in a string or array and save it in different location, later combine everything in one string or array. It will be using simple programming C code. For example (arrays, pointer) but not interrupts or other string functions.
In a sentence like this:
Size= 70
$--GSV,x,x,x,x,x,x,x,...*hh $--GGA,hhmmss.ss,llll.ll,a,yyyyy.yy,b,x,xx,x.x,x.x,M,x.x,M,x.x,xxxx*hh $--GLC,xxxx,x.x,a,x.x,a,x.x,a.x,x,a,x.x,a,x.x,a*hh $--GSA,a,a,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x.x,x.x,x.x*hh
The program must capture the $--GGA string then extract from this string:
1) hhmmss.ss
2) IIII.II
3) a (if a = to N or S replace N or S with + or - respectively )
4) yyyyy.yy 5) b (if b = to E or W replace E or W with + or - respectively )
Save them in an array and display as well. After all the saving, the program should combine them to one string. That the final output.
I have a lab with the following instructions:
Manually create an input text file called Lab22BInput.txt with the following data:
Dove
Doe
Alston
Zebra
Egg
Write a program that will read the names from the input file. Print out each of the names read to the screen. The program should go through the list of names and determine which comes 1st in the alphabet. The program should determine how many letters are in this name. Print out the name that comes first in the alphabet and the length of the name.
I have created the input file, and the data correctly outputs to the screen when I run the program. However, I do not know what kind of logic to use to sort them alphabetically and determine the amounts of characters.
So far I have the following:
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
int main()
{
string str1, str2, str3, str4, str5;

I want to print different color names for "nb " times . I get the number " nb " from the user or from text file . if " nb = 3 " then I want to print any 3 different color names which means that I may print ( red , green , blue ) for example . and if " nb=5 " then I have to print any five different color names ( pink , blue , black , red ,white ) fore example .
Note : " nb " may be a large number ( 17 for example ). How can I do this ?
I need a code for renaming multiple(bulk or all ) files in a folder.
I found one batch file script but it renaming with numbers only. But i want differntly.
[URL] .....
Example:
In a folder there are 100 images and all numbered with some digits or names.
assume that all images are belongs to "john" , so i want to rename all images with "john+ a random string".
here a random string means -> it has an array with 3000 english words, (you can predefine them by downloading from dictonary).
In the script the 3000 names are fixed, but the 1st name will be changed by my wish. that my be john, mary, sai, pavan etc...
Suggestion: you do not need to enter all 3000 words in array manually. some javscript codes are there to read input of each and evey line and them into an array.

The program needs to be able to read the middle names within the text file named Info2.txt
Simply adding the Mname or any related value where the other to name values doesn't do anything and only the 1st line appears on the output.

That is the correct way it appears in the text file. Also I know it's commented out, but that just to keep the program from crashing.

I need my program to read a list of numbers from and input file, random.txt, and calculate the following statistics on those numbers:
A. The number of numbers in the file.
B. The sum of all the numbers in the file.
C. The average of all the numbers in the file.
D. The largest number in the file.
E. The smallest number in the file.

This is what I have so far but I'm not sure if it is right. I can't get the input file to open.
I am at a lost of how to sort names in alphabetical order after having the user input them into a linked list. I manage to create a program that did have the person input names into the linked list and when it is printed it displays the names in the order of how the user inputted the names.

" Write a program that reads into a string object a name with three blanks between the first and last names. Then extract the first and last names and store them in separate string objects. Write a function subprogram that displays its string argument two times. Call this function display the first name for times and then to display the last name six times."
I completed coding the first part of this task with the strings and combining strings together. However, i have having trouble with the other half of this task. It begins from "Write a function subprogram to display the last name six times." This is where i have so far --

The program that I have written below is working. It calculates a number of payroll type variables and most recently the net pay average (All this is working 100%).
My problem is that I need to add first and last employee names to the program but every time I do this I end up ruining the working program. I've successfully added first and last names to similar programs in the past(ones that make use of an array and while loop) but never to a program that uses functions (I always have problems doing this).
My question is what codes do I use to add a first and last name variable and where do I put those codes within my program so it runs/displays correctly.
I think the coding must be similar to what I've used in the past charr and of course firstname[i] and lastname[i] lines.

I have written an program to emulate a shopping list. Everything works fine, until I try to read in from a file. Here is my read and write code (the write code looks like it is working ok, but I figured I would include it just in case), and an example of what happens to a list that has been written, then read back in.
I took this list, and wrote it to a file, then read that file back in. The .txt file looks like everything was written out properly, but when I try to read that exact same list back in, this is what I get:
In my class we were supposed to write a program from the book that inputted the names and votes and the program is supposed to spit out who won the vote.

I cannot seem to get it to work....

I am trying to create an array of file names such that when I want to open one of the files, who's name is given in the array, I can call that element of the array. My code for making the array is the following,
Code:
char file_name[40];
char *file_locations[N]; // array of N names (*)
for(ii=0; ii<=N-1; ii++){ // printing the names of all the files P1_8mag_1.txt - P1_8mag_N.txt
sprintf(file_name, "P1_8mag_%i.txt", ii+1);
[Code]....
The problem with this is that in the first step: all elements of the array "file_locations" are the name of the last file in the loop (in this case "P1_8mag_N.txt")What is wrong with this?
I have .db3 file, and he has 14 tables,and every table has certain number of columns. Example i have table called "BASIC_INFO" and that table has columns "First Name", "Last Name" and "Age".
How can i get name of table and name of every column,so if i some day add column "Male" i get name of this column too. I need first to calculate number of columns,put that in some integer, and then for example create string array which will contain : array[0] = "First Name" ,array[1] = "Last Name"...

I tried this too:

+ "where TABLE_Name='BASIC_INFO'"
+ "order by ORDINAL_POSITION;";
string query = "SELECT TOP 0 * FROM BASIC_INFO";

I'm trying to arrange names alphabetically from a text file. Inside my textfile, it's like : "John", "Edward", "Peaches", "Anna"... etc.(It has thousand more names, all with quotations, separated by comma and I think it's not typed line by line... but using only one line). How can I read each name separately?
this code, it works if the text file contains names separated by lines and without commas and quotations. I do not know with the case I've stated above.
string numbers[1000];
string line;
string number;
string y;
string x;
int z = 1;
ifstream myfile;
myfile.open("names.txt");

This only shows the data inside text file. I'm new in c++.
A teacher has asked all her students to line up single file according to their first name. For example, in one class Amy will be in front of the line and Yolanda will be at the end.
Write a program that will read in a file of names. Names should be read until there are no more names to be read. Use LineUp.txt as a test file for your program.
Once all the names have been read in display which student will be at the front of the line and which one would be at the end of the line. You may assume that no two students have the same name.
These are the name in the LineUp.txt file if needed:
Cooper
Gavin
Joseph
Sierra
Kacie
Dylan
Kaylee
Will
and so on .....
