C++ :: Voter Program - Input Names And Votes / Output Who Won The Vote

Apr 27, 2013

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 did this then while i was reading the assignment from the instructor I noticed he wanted the information inputted from a TXT file instead of manually inputting it. I cannot seem to get it to work....

#include <iostream>
#include <iomanip>
#include <string>
#include <fstream>
using namespace std;
#define N 5
char names[N][20];
float votes[N];

[Code] ....

here is the txt file

Johnson 5000
Miller 4000
Duffy 6000
Robinson 2500
Ashtony 1800

C++ :: Input And Output Files - Names Should Be Read From Command Line

C++ :: Write A Program That Will Read Names From Input File

Apr 24, 2014

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;

[Code]...

Feb 29, 2012

im trying to write a program that prompts the user to enter three numbers and then prints them vertically (each on one line), first forward and then reversed. this is how the design should look:

enter three numbers: 1 43 54

your numbers fowards:

1
43
54

your numbers backwards:

54
43
1

this is what i have thus far when it comes to code....

The problem that I am having is that , the program outputs numbers that are perfect numbers and im not sure where i can add a statement to make it so that if it isn't a perfect number it doesn't output...

#include<iostream>// allows user input/output
#include<conio.h>
#include<fstream>//data file / result file
#include<iomanip>
#include<cmath> // math function
#define in_file "data.txt"
#define out_file "result.txt"

C++ :: Program Will Echo Letter (User Input) And Output Name Of The Day Of Week

Oct 21, 2012

Write a C++ program that does the following:

Prompt the user to enter a day of the week as M (or m), T, W, R, F, S, and U for Monday through Sunday respectively. The user may enter an upper or lower case letter.

When the user enters a character, the program will echo the letter and output the name of the day of the week.

Provide an error trap that reads something like "you have entered an invalid letter; program aborting." Suggestion: use a switch statement with the error trap as the default condition. it is not necessary to prompt for multiple inputs.

So I know how to get the program to echo back the letter and everything. What I am a little confused about is: will I have to define all the letters as their respective day? eg. make M== Monday. And if I do have to do that how would I get it to accept Upper and Lower case letters and recognize that that letter is == monday ect. ect.

Also my main problem is the switch statement as the error trap. I have never used the switch statement, but I know what they do. I just don't really understand how I would use it for an error trap. Am I suppose to just make a case for every other letter in the alphabet other then M T W R F S and U? Even if I do that then what if the user enters a number instead of a letter?

C :: Count Lines In Input And Display Output In Terminal When Program Executed After Compilation

Feb 4, 2013

Code:

#include <stdio.h>
main() {
int c, n1;
n1 = 0;
while ((c = getchar()) != EOF)
if (c == '')
++n1;
printf("%d", n1);
}

I have a more complicated program I'm wishing to have display the output, however, to save some time I'm using an example of a shorter version. count the lines in input and display the output in terminal when ./program is executed after compilation. To count and compute lines, words and within arrays.

C++ :: Command Prompt Will Not Disappear After Input Names?

Nov 12, 2014

Here is a code snippet which is a bit annoying.

Code:
cout << "Put in the names of people, press q to exit" << '
';
while((cin >> people_inp) && (people_inp != "q")){
Person *p = newPerson(people_inp);

[Code] ....

The problem of this code is when you put in the names(via cin) and press enter command prompt will disappear. What should I do so that Command prompt will not disappear after I input some names? I mean it disappears without you pressing a key.

C :: Program To Calculate Students Grades From Input File And Write To Output File

Aug 29, 2014

One of my class assignments is to create a program that receive a .txt file containing a students name and their grades as follows:

John K. 99, 87, 57, 89, 90, 95
Amanda B. Jones 100, 88, 76, 99, 86, 92
etc..

The number of students is unknown until run time. You have to take those grades and average them weighing the first (4) at 10% a piece and the last (2) at 30% each.

Then return an output file with the students name and their letter grade A,B,C,D,F based on their computed score. In addition, on screen it needs to display the average scores for each Q1, Q2, etc. as well as the minimum and maximum for each test on the screen. I am having a hard time in assigning the scores to a variable so that they can then be computed as an average and then used to determine a letter grade. I have begun to write the code and am a bit stuck..here's what I have so far:

Code:

#include <stdio.h>
#include <stdlib.h>
#include <math.h>

[Code]....

C++ ::  program That Reads Into String Object A Name With Three Blanks Between First And Last Names

Oct 4, 2014

" 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 --

#include <iostream>
#include <string>
using namespace std;
int main()
{
// Defining the strings

string firstname, lastname;
string wholename;
string greet = " Hi ";

C++ :: Adding Employee Names In Function Arranged Program

May 13, 2014

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.

Current Input File:
16454025.00
89324020.00
71044012.50
28164026.00
53874021.00
67804013.50
56414011.25

90006025.00
90015020.00
90025523.00

Ideal input file (would include names) Example.
1645 Bob Smith 40 25.00

Syntax:

#include <iostream>
#include <iomanip>
#include<fstream>
using namespace std;
//function prototypes
int readalldata(long int[], int[], float[], const int);
void findovertimehours(int[], int[], int);

C++ :: Program To Pick A Random Name From A File With List Of Names

Oct 28, 2013

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?

C++ :: Program To Read Middle Names Within Text File - Full String Not Appearing

Oct 24, 2014

I've a problem here...

#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <conio.h>
#include <string>
#include <iomanip>
using namespace std;
int _tmain(int argc, _TCHAR* argv[])

[Code] ....

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.

Don Jon111012
Jack Bo Todd151015
Jill Jo Jane161011
Bob Jack Chuck 131513
Da Fu111012

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.

current output

Survey Results:

Name Results
Don Jon 33.00

This is the Info1.txt file info by the way.

Ken A202017
Gus B151015
Bill C151512
Jara C151720
Lu E101510
Chow B171015

And the output

Survey Results:

Name Results
Ken A 57.00
Gus B40.00
Bill C42.00
Jara C52.00
Lu E35.00
Chow B 42.00

Which when ran with Info1 selected, it is the correct output I'm looking for. I've tried getline and other solutions and they didn't work.

C :: Redirecting Input And Output

Sep 14, 2013

I have this code:

Code:

#include <stdio.h> //printf
#include <stdlib.h> //exit
#include <unistd.h> //fork
#include <sys/types.h> //pid_t
#include <sys/wait.h> //waitpid
}

[code]....

I would like to, when running cat, send in some data like "testing" to its stdin, and then catch the output of stdout, and put it into a character array variable.Currently the parent stalls till the child is done.I imagine the parent has to some how detect that the child executed 'cat', and then send in input to stdin?Then somehow detect that 'cat' is done executing, and read the output from stdout? I have looked around and found "dup2", but I don't understand how to send in and get data to the child from the parent, especially since the "file descriptors" is not pointing to any files in the first place..

C++ :: Zero And Output The Input With A Setprecision Of 2

Mar 31, 2013

I have a program that needs to output the input with a setprecision of 2 but when it outputs 0, it has to be "0", not "0.00"

How will I go about that?

Here is my code:

void PrintAllSales(double sales[][SLSPRDT]) {
cout << fixed << showpoint << setprecision(2) << endl;
cout << "ALL SALES
";
WriteLine('=', 63);

[Code] .....

And here is how it comes out:

1234
ALL SALES
===============================================================
Product # | 1 | 2 | 3 |
Salesperson 1 | 2000.00 | 0.00 | 299.00 |
Salesperson 2 | 0.00 | 2543.98 | 95.99 |
Salesperson 3 | 0.00 | 0.00 | 19.99 |
Salesperson 4 | 0.00 | 3854.75 | 0.00 |

But it should be like this:

1234
ALL SALES
===============================================================
Product # | 1 | 2 | 3 |
Salesperson 1 | 2000.00 | 0 | 299.00 |
Salesperson 2 | 0 | 2543.98 | 95.99 |
Salesperson 3 | 0 | 0 | 19.99 |
Salesperson 4 | 0 | 3854.75 | 0 |
