C/C++ :: Given Person Birth-date Or Any Other Date Will Display Day Of Week
Oct 11, 2012i'm making a program that, given a person's birthdate or any other date, will display the day of the week of the person was born.
There is this part where it says "use a switch statement to make this calculation, If desired month is 12, add the number of days for November, if desired month is 11 add the number of days for october....
So it's suppose to start with "case 12 :...

C++ :: Validate Unsigned Operations?
Oct 12, 2012I've sometimes encountered unexpected runtime issues caused by unsigned values being decremented below zero.
Example 1: "unsigned_value += negative_integer_value;"
Example 2: "for( size_t i = size - 1; i >= 0; --i )"
My compiler doesn't provide any compile-time or run-time warnings.
As far as I know, it's not possible to overload operators of primitive data types to check if the unsigned value is decremented below zero.
Any clever strategy to trace such cases at debug runtime, without having to add asserts all over the code? It's important that it does not affect performance in release mode.

C++ :: Using While Loops To Validate String Input
Jul 2, 2013Im having trouble with the while loop, this program should ask the user for their name, if incorrect it should send an error msg and ask for input again...after the correct name is entered the program should prompt the user to enter a password, again if incorrect it should send an error msg and ask for input again.
the code below does what it should when asking for a name..HOWEVER it does not allow the user to enter a password and instead jumps straight to the error msg..
#include<iostream>
#include<string>
#include<iomanip>
using namespace std;
int main() {
// Variables
string username;
string password;
[Code] .....
After the correct name is entered, the program displays this:
"Welcome, Sadia Rajput."
"To continue, enter your password: That is incorrect, enter password: "
I would prefer to do this using the while loops and not bool statements
C/C++ :: How To Validate Data Stored In A File
Jun 21, 2014I am trying to build a employee management system using C, and I have done alot so far. Everything seems to work fine, but then I thought that I should let the user store the data of their employees permanently, therefore I created a file and then I store the user's given data in the txt file.
Here is the code:
#include<stdio.h>
#include<conio.h>
#include<string.h>
[Code].....
But there is some problem, and I don't seem to understand what is the problem in the code, it's just that whenever the user enters any id to search, and presses any key then nothing appears just a blank screen! I wanted to know that how can I check the ID from the text file and then display the details of the employee of that id!

View 1 Replies View RelatedC++ :: Getting User Input In Date Format
Oct 26, 2014So I have a programming assignment which is for getting a user input in the format of m/d/yyyy. This is stored as d/m/yyyy. I have been able to code all the rest of the requirements of the program but the thing that is giving me trouble is this. The year is allowed to go from 1-3000. The format of the displayed date is:
a zero-filled, two-digit day number, a dash, full name of month, a dash, zero-filled, four-digit year.
I am able to use a switch statement in order to get my name of the month. What I am struggling to figure out is the whole zero filled two digit day and zero filled four digit year. From the way the input is store it appears to me that it will be stored as yyyy which means if you were to enter 0001 for year 1 then it should output it as that (this is an assumption based on format). What I don't get is that the day is entered and stored as d which means if you put in 12 how would it be stored. However if you put in 6 to print the output I would need to add a zero and I dont know how to do that either.
Here is the code for getting the input. The function must stay formated this way as per the instructor. The / is stored but ignored hence the char for second and fourth since / is a char
Code:
void getDate (int& day, int& month, int& year){
char second;
char fourth;
cout << "Please enter a date in the format of m/d/yyyy" << endl;
cin >> month >> second >> day >>fourth >> year;
}
C :: Date Math Using Standard Libraries?
Dec 22, 2013Is there any way to do date math using standard C libraries? I looked around in the time.h but didn't see what I needed.
What I need to do is be able to add a certain number of minutes to a date and have it give the current date/time. For example, add 15918765 minutes to 01/01/1980 00:00 and have it tell me 04/07/2010 4:45PM. I really don't want to write this myself or go platform-specific.
Does this exist somewhere or am I SOL?
