The problem here is that after taking the mobile number it doesn't give me a prompt for email id or taking input for any other fields.It just gives me the output.And even in the output the mobile no. is turned into some garbage value not the original no. I entered.I really don't know whats going on.Can someone help me!
I have run the code on ubuntu and c++ shell online and they both seem to give me same results.
I don't know what this problem is called so don't get angry at me for asking this question!
You are storing the mobile number as an int, which has a max size of 32767 http://www.cplusplus.com/reference/climits/
8552004340 is too big!
Better to store it as a string.

I am to create an application that takes at least 5 employees i.d, names, pay rate, and hours. And then I am to add the pay rate and the hours together to show the gross pay for each employee at the end of the initial inquiries. I am stuck on how to add it in the vector please help!
** Here is the assignment that our instructor gave us **
http://itweb.fvtc.edu/ag/?u=3&f=cpp-assignment4
I've added a vector and added all the essential information for the employee

//This is what i got so far. But if I want to make the application ask the user to input how many employee they want to enter into the database how do i do that? would it be like this?
int EMPLOYEE_NUM[][] // ??
So the purpose of the program is to Create an array of 3 people, allow the user to populate the data in a for loop, ensure that the results are capitalized, and output the results.
These new projects instructions were to
1. Rewrite capitalize() as a method within the structure.
2. Rewrite printPerson() as a method within the structure
The program itself works just fine, it's just not in the format that my professor wanted. He said the point of it is to not use any arguments but again, I don't know what he means. I just started programming a few months ago and even though I'm trying I don't have a strong knowledge of the terminology.
#include <iostream>
#include <string>
#include <algorithm>
using namespace std;
struct Person {
string firstName;
string middleName;
string lastName;
int age;
string gender;
void capitalize(Person &arg);
void printPerson(Person arg);
};
Pretty sure these are the methods right here, but I'm not sure if the (person &arg) and (person arg) are the arguments itself or if they are parameters. I thought it was the "arg" part but I can't find a way to get the program to run without them as I'm pretty sure I need the & of operator to modify the information.
int main(void) {
Person myPerson;
Person a[3];
const int size = 5;
for (int i = 0; i <= 2; i++) {
cout << "What is First Name #" << i + 1 << "? ";
getline(cin, a[i].firstName);
cout << "What is Middle Name #" << i + 1 << "? ";
getline(cin, a[i].middleName);
cout << "What is Last Name #" << i + 1 << "? ";
getline(cin, a[i].lastName);
cout << "Age #" << i + 1 << "? ";
cin >> a[i].age;
cin.ignore();
cout << "Male or Female #" << i + 1 << "? ";
getline(cin, a[i].gender);
cout << endl;
}
for (int i = 0; i <= 2; i++) {
myPerson.capitalize(a[i]);
cout << "PERSON #" << i + 1 << endl;
cout << "~~~~~~~~~~~~~~~" << endl;
myPerson.printPerson(a[i]);
}
system("pause");
return 0;
}
Along with that, I don't know how to manipulate the functions to work without the "parameters/arguments" (I'm not sure the difference at this point) or without the "arg"
void Person::capitalize(Person &arg) {
transform(arg.firstName.begin(), arg.firstName.end(), arg.firstName.begin(), ::toupper);
transform(arg.middleName.begin(), arg.middleName.end(), arg.middleName.begin(), ::toupper);
transform(arg.lastName.begin(), arg.lastName.end(), arg.lastName.begin(), ::toupper);
}
void Person::printPerson(Person arg) {
cout << "\nFirst Name: " << arg.firstName << endl;
cout << "\nMiddle Name: " << arg.middleName << endl;
cout << "\nLast Name: " << arg.lastName << endl;
cout << "\nAge: " << arg.age << endl;
cout << "\nGender: " << arg.gender << endl;
cout << "\n\n";
}
The capitalize and the printPerson are now members (usually called methods) of the struct Person. This means that they operate on the member variables of an Person instance. Like this, you can just access all the classes members in these methods. See the following code. I also completed it with a constructor and made it slightly more readable.
#include <iostream>
#include <string>
#include <algorithm>
using namespace std;
struct Person {
public:
Person();
void readFromUserInput();
void capitalize();
void print();
public:
string firstName;
string middleName;
string lastName;
int age;
string gender;
};
Person::Person() :
firstName(""),
middleName(""),
lastName(""),
age(0),
gender("")
{
}
void Person::readFromUserInput()
{
cout << "What is the First Name ? ";
getline(cin, firstName);
cout << "What is Middle Name ? ";
getline(cin, middleName);
cout << "What is Last Name ? ";
getline(cin, lastName);
cout << "Age ? ";
cin >> age;
cin.ignore();
cout << "Male or Female ? ";
getline(cin, gender);
}
void Person::capitalize()
{
transform(firstName.begin(), firstName.end(), firstName.begin(), ::toupper);
transform(middleName.begin(), middleName.end(), middleName.begin(), ::toupper);
transform(lastName.begin(), lastName.end(), lastName.begin(), ::toupper);
}
void Person::print()
{
cout << "\nFirst Name: " << firstName << endl;
cout << "\nMiddle Name: " << middleName << endl;
cout << "\nLast Name: " << lastName << endl;
cout << "\nAge: " << age << endl;
cout << "\nGender: " << gender << endl;
cout << "\n\n";
}
int main(void)
{
const int NUM_PERSONS = 3;
Person a[NUM_PERSONS];
for (int i = 0; i < NUM_PERSONS; i++)
{
cout << "### " << (i + 1) << ". User:" << endl;
a[i].readFromUserInput();
cout << endl;
}
for (int i = 0; i < NUM_PERSONS; i++)
{
a[i].capitalize();
cout << "PERSON #" << i + 1 << endl;
cout << "~~~~~~~~~~~~~~~" << endl;
a[i].print();
}
system("pause");
return 0;

i'm trying to load the file into an array when the program starts so i can
modify or search in it i don't know if my code works or not ( it's not reading the file )i have the file
and there's two books in
i have tried to debug it but couldn't find the problem the code works
but it think there's a problem with the load() function i don't know what
my code :
#include <iostream>
#include <string>
#include <fstream>
#include <iomanip>
using namespace std;
struct books{
//identfying books with all needed things
int id, status;
string title, p_name, p_address;
string date;
string aut_name, aut_nationality;
}newbook[10000], aut[10000];
int i = 0;
void load(){
ifstream myfile("books.txt", ios::in);
while (myfile >> newbook[i].id >> newbook[i].title >> newbook[i].p_name >> newbook[i].p_address >> aut[i].aut_name >> aut[i].aut_nationality >> newbook[i].date >> newbook[i].status)
i++;
}
void search_for_book(){
int temp = 0;
int idx;
cout << "enter the ID of the book you're looking for : ";
cin >> idx;
for (int srh = 0; srh < i; srh++){
if (newbook[srh].id == idx){
cout << setw(10) << "book found :" << endl;
cout << "title :" << newbook[srh].title << endl;
cout << "publisher name : " << newbook[srh].p_name << endl;

cout << "author Nationality :" << aut[srh].aut_nationality << endl;
cout << "publish Date :" << newbook[srh].date << endl;
cout << "status :" << newbook[srh].status << endl;
temp++;
break;
}
else
srh++;
}
if (temp == 0){
cout << "couldn't find book" << endl << endl;
}
}
int main(){
load();
char choice;
cout << "enter your choice (3)";
cin >> choice;
if (choice == '3'){
search_for_book();
}
}
note :*( there are other functions like adding new book but not necessary to write )
*(i'm new to c++ don't really know how to read file into memory but i'm trying)
this is the code to save data into file :
void add_new_book_5(){
int booksnumber;
books newbook[1000], aut[100];
cout << "how many books you want to add ? ";
cin >> booksnumber;
cout << "what books you want to add :" << endl;
d_base.open(path, ios::out | ios::app);
for (int i = 0; i < booksnumber; i++){
cout << "id please : "; cin >> newbook[i].id;
cout << "title : "; cin.ignore(); getline(cin, newbook[i].title);
cout << "publisher name :"; getline(cin, newbook[i].p_name);
cout << "publisher address : "; getline(cin, newbook[i].p_address);
cout << "author" << " name : "; cin.ignore(); getline(cin, newbook[i].aut_name);
cout << "Nationality : "; getline(cin, newbook[i].aut_nationality);
cout << "Publish date :"; getline(cin, newbook[i].date);
cout << "How many copies of " << newbook[i].title << " "; cin >> newbook[i].status;
system("cls");
d_base << newbook[i].id << "\ " << newbook[i].title << "\ ";
d_base << newbook[i].p_name << "\ " << newbook[i].p_address << "\ ";
d_base << newbook[i].aut_name << "\ " << newbook[i].aut_nationality << "\ ";
d_base << newbook[i].date << "\ " << newbook[i].status << endl;
}
d_base.close();
cout << setw(76) << "Books Have Been Saved Sucessfully" << endl;
}
I need help understanding the [Error] id return 1 exit status due to 2 undefined references: getGrades() and getAverage(). I was issued DEV C++ and knocked out the syntax errors with mild frustration but these "linking" errors are still giving me a hard time. This is the most recent update of the code, if anyone could help me understand these linking errors that would be great.

my program seems to want to enter two inputs for name variable instead of just entering one thing and moving on to phone number?
i'm sure its simple but can someone help me fix this please? is it something it do with the getline?
#include <iostream>

#include <vector>

thespeaker = *getSpeaker();
cout << "The speaker entered is!" << endl;
cout << thespeaker.name << endl;
cout << "phone number: " << thespeaker.phoneNumber << endl;

There's no need for cin.ignore();
Simply write it as:
Speaker *getSpeaker()

theSpeaker = new Speaker;
cout << "Please enter Speakers information" << endl;
cout << "name: " ;
getline(cin, theSpeaker->name);
