I need to create a function that performs the addition of x days at a time, taking two integer values, the first being a date (yyyymmdd format) and a number of days to add / subtract that date.
How can I perform validation if the entire amount received is a valid date and how can I add x days of that date?
I have to write a c++ program with my own function which consists of two parameters (day, month). Function have to return number of days since the begining of this year. Using this function i have to find out how many days are left till birthday (or how many days have passed since last birthday)
This is how far i am:
Code:
#include <iostream>
using namespace std;
int cikDienu(int diena, int menesis);
int main()

For class I need to write a program that inputs a file (the dividend), performs binary division on the file (using 0x12 as the divisor), and outputs the remainder(checksum).
I have researched binary division algorithms and I get the general gist, but I'm still unsure where to start. How would I store the dividend and divisor? As two arrays of bits?
Then, I need to figure out how to perform shifts and XORs on the the binary numbers. Maybe I should use bitwise operations?
I would like to have a program with a 5 mb string embedded in it kind of like this:
Code:
const char *c;
c = (const char*)"BEGIN_STRING_HERE, (5 MB of arbitrary values here)";
Is it possible to generate this string at compile time? Maybe with a macro? I'm trying to avoid a source file with a 5 mb string in it.
I am trying to create a program that calculates fraction of time remaining when a student leaves during the middle of the semester. I have to use function files here. I am having trouble with the division in function long double tuitionfrac(int, int, int). No matter what numbers are entered, fractime gives an output of 0. I don't understand that.
long double tuitionfrac(int opening, int leaving, int semend)
{
int lefttime = semend - leaving;
cout << "Left time " << lefttime << endl; //for error checking
int tottime = semend - opening + 1;
cout << "Total time " << tottime << endl;
long double fractime = lefttime/tottime;
cout << "fractional time " << fractime << endl; //always returns as 0.
return fractime;
}
I am trying to create two classes: a Date class and a Time class. The Date class has to have three private data members: day, month and year. The Time class should have two private data members:hour and minute. Each class should have two member functions: a constructor and display. I am lost and my code won't run ....
class Date {
private:
int month, day, year;
public:
Date(int m, int d, int y){
month = m;
day = d;
year = y;

I'm trying to create a program to calculate the flight time and fuel burn of an airplane. However when I repeated the whole calculation, it did not show any data or result like the previous calculation. In addition, the "If" statement that I used to test the "fuelRemain" doesn't work properly. I can't figure out why.
Here are the outputs [URL]

I have a struct called Array and I'm to create a function to create a dynamic array that's fill with randomly generated integers from 0 to 50 (inclusive) and a function to destroy the array for freeing its memory. Below the code that I have written so far.

typedef struct {int *pArray; //the dynamic array
int length; //the size of the dynamic array}Array;
/* Function to create a dynamic array */
Array *initializeArray (int length) {int i;

What my ultimate goal here is to make a program that asks the user how many numbers they would like to add followed by asking the user what numbers they want to add. I want the amount of numbers they can add to be infinite and have the loop continue adding the numbers until it reaches the final number. I just need to know how to do this.
Here's my code:
#include <iostream>
#include <string>
using namespace std;
int main() {
//variables
int amount;
float num;
float sum;

I have created this code with the classes for time and message. Basically the point of this code is to give the information of the sender, recipient, time, and message and im having issues with the time part.
#include <iostream>
#include <string>

so when you run this you can see i left a spot for the time but I just cant figure out how to figure out the Time part of this.
I am in a computer science class at LSU and i can not figure out how to writhe this program. The program must let the user input (MM/DD/YYYY) and then output what day that date was on and also if it was a leap year or not.

I'm working on a matrix class and I've hit a few snags. Here's what I've got so far:
Matrix.h
#include <iostream>
#include <conio.h>
using namespace std;
class Matrix {
private:
int matrix[50][50];
[Code] ....
Where I have questions is in implementing the addition and subtraction bits into the class itself. I understand that I'm going to have to do a copy operation (this from reading in C++ Primer Plus 5th Edition). Right now I'm just after adding/subtracting as the rest will be variations on the same theme.
So, here it goes:
As I understand the problem, I need to pass my two matrices as arguments to an addition function. This is going to involve having to copy the values of the two existing matrices into temporary matrices within the addition function, then I'll add them, and store them in a new matrix which will be my return value. So...something like this:
int Matrix::matrixAdd(int R, int C, const Matrix & matrix1, const Matrix & matrix2) {
int sum;
Matrix matrix;
for (int i = 0; i < R; i++)
[Code] ....
I do end up with errors there...C2240, and C2662. Again, I'm new to working through this, but that's what I've got. My idea is that I'm passing the maximum size of the array as defined by the user, in this case a 2x2 array, it'll cycle through and add up to that imposed limit...I went 2x2 because it's small enough that testing doesn't drive me up a wall.
How exactly did u accept it as a string? i mean did u use ascii values or anything? and what was your code for keeping track of carry?

If you don't introduce a value in 3 seconds the program will go further.

I'm writing an addition and subtraction calculator that takes input as: 5+6-3+2. You should be able to add or sub as many numbers as you want. I want the while loop to stop when the user hits enter. I put the getchar() function to catch the and break the loop but it is also swallowing the '-' sign, which I want to use to subtract and is instead adding the numbers with "sum+=number". How can I get around that?
Code:
#include <stdio.h>
int main(int argc, char *argv[]){
int number, sum = 0;

I have to write a code in which the addition of prime number gives the number user input..
for example if user enters 10 then
7+3 = 10
2+3+5 = 10
I have two questions that are related to each other. The first one is about overloading the addition operator.
I have defined a struct as the following:
Code:
#include <iostream>
#include <string>
struct Sales_data {
[Code] ....
I then overloaded the I/O operators so I could print to the screen information related Sales_data.
Code:
// overload ostream in order for cout to work
std::ostream& operator << (std::ostream & out,
const Sales_data & cSales_data) {
out << cSales_data.bookNo << ", " << cSales_data.units_sold << ", "
[Code] ....
My first issue is with overloading the addition operator. Everyone works correctly except for std::cout << item << std:endl; will no not output the ISBN number only the units_sold and revenue when added together.
Code:
// addition operator rules
Sales_data Sales_data::operator + (const Sales_data & data2) {
units_sold += data2.units_sold;
revenue += data2.revenue;
return *this;
}
Now here is the code in its entirety
Code:
#include <iostream>
#include <string>
// Sales_data structure
struct Sales_data {
std:: string bookNo;
unsigned units_sold = 0;
[code] .....
After total = total + item;, I would like to print the total for this particular ISBN. However, I only get: blank, total units, total revenue where blank is where the ISBN would go but doesn't print after addition. My second question has to do with comparing the ISBN's of the books entered during the while loop. I would like to do something like
Code:
if (item_i.bookNo == item_i+1.bookNo) {
total = total + item;
} else {
std::cerr << "Books entered must have the same ISBNs" << std::endl;
}
Unfortunately, I cannot figure out how to set up a comparison of the bookNos. If I used #include <casset> in the overload + rule, it will immediately exit since I have no way to compare the ISBNs.
