C :: How To Write A Program That Gives Few Default Values
Oct 11, 2014
I would like to write a program that gives you a few default values. Now you can keep these values by pressing the enter key or you can change them by just typing in new ones and confirm the new values by pressing the enter key again.
Thats as far as i got on my own but it doesn't really work. what i can do to fix this.
Code:
#include<stdio.h>
#include <conio.h>
int getInt(int min, int max);
int main () {
int a[3] = {3,4};
int b;
int code;
[Code]...

How do you write a default constructor?I need to use a default constructor that will initialize the data members:
- salesPerson to “Unknown”
- noOfWeek to 13
- amount to point to an array of thirteen 0.00s.
This is my weeklysales class
class WeeklySales {
char* salesPerson;
double* amount; // Pointer to an array
int noOfWeek; // Size of the array
};
Here's my attempted code:
//default constructor
WeeklySales (){
salesPerson="Unknown";
noOfWeek = 13;
amount = 0.00;
}

Same solution that I was having compiler errors on yesterday. We're working with inheritance and the program is supposed to be to create and display information for default Employee objects, Hourly Employee objects and Salaried Employee objects. Everything compiles as is, but I'm running into two issues that I can't figure out.
1) In both the hourly and salaried objects, the wage, hours, and management level attributes all displaying their default values. I'm almost positive that this has something to do with the str to int and str to double conversions that I'm using (currently have atoi and atof in the file, but I've also tried stringstream, but still had to same problem). Any thoughts as to what I'm missing?
2) the assignment calls for the Benefit benefit member in Employee.h to be protected. However this makes the member unaccessible when I try to use it in the EmployeeMain.cpp in order to set the input for the Benefit class members. I had to make the Benefit benefit member public again to get it to compile. How would I set the input for the Benefit class members while the Benefit benefit member is protected?
Solution files follow:
EmployeeMain.cpp
Code:
#include "Hourly.h"
#include "Salaried.h"
void DisplayApplicationInformation();
void DisplayDivider(string);
string GetInput(string);
[Code]....

#include <iostream>
#include <vector>
void f(std::vector<int> const &v, std::vector<int>::const_iterator it = v.end()) {
} int main() {
f({}); }
prog.cpp:4:73: error: local variable ‘v’ may not appear in this context
void f(std::vector<int> const &v, std::vector<int>::const_iterator it = v.end())
Why is this not allowed? (I mean, what is the reasoning for defining the standard this way?)
In C++14/C++17 we will have a unified way to represent end iterators without an instance of the container, but currently I just have to hope my implementation accepts a default-constructed iterator as an end iterator.

Is it possible with C# to get the default program for an extension? I've already done some research for it, but the only thing I've found out is a way to make my program the default program for an extension. So I my question is, is it possible to use anything similar to check if there is already an default program for an specific extension and which program is it?

So I have a function like the one below
bool get_array( float input_param, vector<int>& output_param ){
// some code that handles output_param output
if( error ) return false;
}
So basiclly this function must return 2 value well one of the value is just a bool returning whether the procedure doesn't fail at some point or not.
is there any better way to write this function ?

correct the below code:
file already contains entries : 1st row username; 2nd row password.
check status required to write at third line and need to read or alter the check status value.
Currently this code is working if already there is a value for check status, then it is overwriting else UI hanging.
Code:
WriteCheckStatusToFile(BOOL& locVar) {
FILE *l_pFile = NULL;
CString l_strRememberCheck;
l_strRememberCheck = GetExePath() + _T("password");
CString sVar;
sVar.Format(_T("%d"),locVar);

I have a batch of .pdf files (~1000) with names 001.pdf 002.pdf ...etc. Still pretty new to C, but would it be possible to write a program that would open a PDF, prompt a new name from user, and when entered, close the .pdf and open the next one in the list?

Here I was trying to write a program to copy one file to another.
Code:
#include <stdio.h>#include <stdlib.h>
int main(int argc, char *argv[])
{
FILE *fp , *ft;
[Code]....
So it should copy test1 to test2. Now I created test1 in gedit. I just put one character "c" in it and closed it. And I ran the program. When I check sizes of test1 and test2 , using
ls -l
command, I see that test2 has 4 bytes and test1 has 2 bytes. So something strange is happening here. I just put a single character in test1, so shouldn't it show 1 byte ? And why test2 is showing 4 bytes ? I have Win XP on my laptop. And I use Ubuntu 12 inside VirtualBox. So this is Linux environment...

-Create three files namely all_numbers, odd_number and even_number.
-Get the number of records and the numbers to store from the user.
-Save all the numbers in "all_numbers" file.
-Read each number and check whether it is odd or even.
-Store the odd numbers in odd_number file and even numbers in even_number file.
-Finally, print the numbers stored in odd_number and even_number files.
The output of the program will look like this.
How many records that you want to store :41
2
3
4
The data are written too the respective files.
The even numbers are 2 4
The odd numbers are 1 3

I assume floating point numbers in C++ have a default maximum of 5 decimal places. You can use setprecision() but is this limitless?
So how would find say write a program to calculate Pi to N number of places?

Write a program that reads data from a file (use the attached data file). These data are a student name and 3 test scores. The program should calculate the average of the 3 test scores, and display the name, 3 test scores, and the average to the monitor.
Useful tips:
a) Include the following header files: iostream, fstream, iomanip, and string
b) The name of the data file is “datafile.txt”, you need to save the file in the same folder of the source file.
c) use the manipulators (setw, setprecision, setfill, showpoint, fixed) to format the average with 1 digits after decimal point as following.
d) Use character ‘ ’ for tab.
