Visual C++ :: Create A File That Ask The User To Enter His Info
Nov 9, 2014
What I want to do is create a file that will ask the user to enter his info,n then store it in a text file The screen will ask the user if he wants to update his info. if he says yes then the screen will be cleared and the old info will be printed on the screen. The user will enter his new info that will be stored in a new file. My problem is that once the user finishes entering his input the program just closes D: and the rest of the program won't run.
Code:
int main()
{
string ans;
ofstream Xfile("original.txt");
cout <<"Enter your name and address please"<<endl;
cout<<"Press Ctrl+Z+Enter when you are done"<<endl;
string name_and_street;
[Code]...

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):
// Password Log
#include <iostream.h>
#include <fstream.h>
#include <string>
#include <time.h>
using namespace std;
ofstream login;
[Code] ....
What my problem is when I choose "Input new login info" it automatically inputs I have no clue, and calls next program.

I have a program that uses class functions to enter and print out info. The problem is with the second function answers(). Here is the whole cpp file. In the answer function I need to use an exception to exit when its the end of an array. I could just be doing it wrong. I used try/catch originally but when I used it, it caught the exception but ended the whole program.
#include <iostream>
#include <cstdlib>
#include "answering_machine.h"
using namespace std;
void AnsweringMachine::init(){
numMessages = 0;

My program was to allow the user to enter a value as a C string in the form: xxx,xxx,xxx,xxx,xxx.xx, where x can be any digit. Well, so far here is my attempt. I think the question is, would I have to implement a switch statement for the digits, the comma, and the decimal, so that when a user inputs, let say 52,000.00 the switch statements would read the 1st digit, checks for decimals/commas and if not, proceed to read 2nd digit, and repeat?
Code:
#include <iostream>
#include <string>
int main() {
using namespace std;
char buffer[256];
char tempBuff[256] = {'

How can I create in my C++ program so a user can paste a text and then choose a character on specific line and place?. The above thing isn't that important. I just want to place a character on a specific line and place.
I mean something like this:
Enter a character:
You choosed " / "
On which line do want the character?
You choosed "Line 1 and 2"
Where do you want the the to appear on the line? (left or right)
You choose left.
Results:
Line 1. / hello
Line 2. / hello

I'm expected to write a c program for this question :
Using these header files
#include <stdio.h>
#include <conio.h>
Question : Write a program that will prompt the user to enter an integer value and a character code to indicate whether they want to do a Kilogram to Pounds conversion (A) or a Pounds to Kilogram (B) conversion. Note that 1 kg = 2.2 pounds. The program should then do the necessary conversion indicated by the code and display the newly converted value to the screen.

I am trying to write a program that ask the user to enter a sentence and then a word to be searched for in the sentence. The program must then search for the word in the sentence in a loop and continue to output each place the word is found. For example if the sentence is : I like pickles, pickles, pickles
and you searched for pickles it would return pickles found at 7, pickles found at 16, pickles found at 25.
I am having trouble writing the equation to make the find keep searching after each occurrence of the word being searched. Here is the code I have so far
HTML Code:
#include <iostream>
#include <string>
using namespace std;
int main() {
string paragraph;

Actually the below program is for Dispersal Algorithm called Rabin-IDA; this algorithm divided the data into N pieces and then recombine it from M pieces (such that M<N).
Thus, the below program needs command line arguments,which entering by Project properties/Debugging. this argument is file name, where the program performing spitted the file into N files, and then recombine it from M divided files, and put it on another file which should also passing its name as argument .
Now my question is, How can i make this program enter the file name by keyboard??(i mean enter the files name by user from screen not as command line arguments) ... In another word, How I can exchange ?
Code:
argc == 3
and
Code:
argc == 2
To enter file name ? i mean what i should do to in
Code:
rabin.split(argv[1])
To pass my file name by use keyboard not Project properties/Debugging?)
the below code is just the main function of program, and the whole of it in this link [URL] .... Information Dispersal Algorithms Rabin-IDA.
Code:
#include "include.h"
void __cdecl _tmain(int argc, TCHAR *argv[]) {
DWORD ini=GetTickCount();
try {
if( argc == 3 ) //recombine
[Code] ....
I know I should use getline() function but how exchange argv[] ?

So I have an array of my own class, "Restaurant," but I'm having a hard time figuring out how to store the info entered by the user into the array.
In total, I have two classes. I will show you all I have, it's a lot but I know it will be easier to understand.
My problem is in the AddRestaurant(), since that is where I should ask the user for all the information and store it in the array.
Also consider that I have to use the FTime class as well to handle the time. Basically I want to do something like this:
info[count].SetRating();
which will put the rating part of the class Restaurant into the array[count]
Also, my program doesn't compile because of the AddRestaurant and PrintAll functions since what I am showing is what I want to do, not what works.
//main.cpp
#include <iostream>
#include <iomanip>
#include <string>
#include "Restaurant.h"
#include "FTime.h"
int ReadMenuChoice();

I am a beginner with C++, taking a class right now. The lab this week is to create a user defined class and have it accesses in a separate .h header file from the main.
I think I'm finding my way through it, but I'm getting a complie error that makes no sense to me:

I am trying to make a program that will allow a user to enter their name, from this point, three options should be present for the user to choose, then from that point, two more options should be present. I have if else statements in a switch case and I get the "undeclared" error for the a in the first " if(specificage == a) ".
NOTE: I use Code::Blocks.
Here is the code:
Code:
#include <stdio.h>
#include <string.h>
int main(){
char name[50];
char ageclass[50];
char specificage[50];

I can tons of information by calling DeviceIoControl (such as device ID, device description, whether it's connected or not) since I couldn't do it all with WMI. But I haven't figured out how to get from DeviceIoControl the info that a call to WMI's Win32_PortConnector gets. Are there any calls, directly to DeviceIoControl or something else that for a given device ID or device description would get the PortConnector information?
I would have used a combination of Win32_PortConnector and DeviceIoControl calls but the trouble with PortConnector is that it doesn't provide any information that would allow one to figure out which device ID it belongs to. Why do I need to do this? Because I'd like to get a combination of all the information the two methods provide for a given device such as a USB port, and all I'm getting from Win32_PortConnector is these scant few fields with no other clue:
string Caption;
string ConnectorPinout;
uint16 ConnectorType[];
string CreationClassName;
string Description;
string ExternalReferenceDesignator;
datetime InstallDate;

I am trying to write up something to have a user to enter a four digit number. Only four digits, Ex: 0001, 0116, or 9999. There is no getting around the selection 0001 or 0002. I understand if not done correctly, the first three 0's will be ignored.
I've been just playing around with what I have below but I just don't remember how to do it nor can I find a good example online to figure it out. I know it is not correct just typing to try to remember. I am aware that it is gibberish right now, this is just me brainstorming.
int number;
cout<<("Please enter the four digit number(Ex: 0001):
");
cin>> setw(2) >> number;
cout<<)"Please enter four digit date. Two digits for month and two digits for year:
");
cin>> date;
if (number< || number > 30)
cout << "Invalid choice. Try again." << endl;
cin.clear();

For my code, I want the user to enter 4 integers, which get stored in an array. Here are the lines I wrote relevant to this part:
Code:
printf("Enter 4 integers:
");
scanf("%d %d %d %d," &a, &b, &c, &d);
z[4] = { a, b, c, d};
Would this be correct?

I'm trying to validate my input. I require for the user to enter six doubles and if they don't then I want them to re-enter the information. Here is my code:
Code:
while (1>0) {
printf("Please enter arguments in the order: negative mass, positive mass, initial x-position, initial y-position, initial x-velocity, initial y-velocity:
");
if ( scanf("%lf %lf %lf %lf %lf %lf",&MassMinus,&MassPlus,&Pos[0][0],&Pos[0][1],&Vel[0][0],&Vel[0][1]) != 6) {
printf("Not all numbers were assigned!
[Code] .....
At the moment it just waits if you enter less than six numbers and if you enter any more than 6 it just ignores anything after the sixth number (so pretty much does nothing). Also if I entered 1 2 a b 3 4 instead of entering six numbers it would register that as 1 2 0 0 3 4 but I want it to make the user input the numbers again. I'm also aware that "while (1>0)" isn't good programming form but I'm not really sure what to use instead?

When the user gives no input, they have to press enter twice before "Done." is printed.
cout << "What do you want the name of your page to be? ";
std::getline(cin, pageTitle);
if (cin.get() == '
')
pageTitle = "Welcome to Website.";
cout << "Done.
";
Is there a way to print "Done." after pressing enter once?

Write a C++ program that asks the user to enter an even number only. If the user enters an odd number the program should use input validation to ask the user to enter another number.
- The user can enter as many numbers as he wants
- The program should also keep a count of how many numbers entered and display how many odd and even numbers entered.

I'm doing an exercise which involves for the user to enter the size of the dynamic array and then enter the numbers, but then it needs to create another dynamic array with the same numbers expect if the number repeats it only has one of it. I've done the first part of the exercise but I'm having trouble with creating the new array.

example" ALEX
A=1
L=12
E=5
X=23
1+12+5+23= 41 //since its bigger than 20 you add 4 and 1 together so it will be 5. after that you print the 5th element of array

Enter as many numbers as you want as long as the user doesn't type 'e' to exit.
Problem: When I enter a number, it works fine, but if I enter e then it'll go in an infinite loop since the letter is being stored in an int variable. How can I (when I press 'e') make it convert to a char to make it end the program?
#include <iostream>
using namespace std;
int main() {
int num;
cout << "Enter a number or press e to exit:";
[Code] ....
Our class has just started c++ and we have not learned arrays and classes yet, so I'm guessing there is a way to do this without it? Or no?
