C++ :: Program To Generate Calendar For A Year

Oct 15, 2013

Problem: Write a program to generate a calendar for a year. The program should accept the year and the day of the week for January 1 of that year (0 = Sunday, 1 = Monday, etc.). The calendar should be printed in the following form:

January
1
2 3 4 5 6 7 8
9 10 11 12 13 14 15
16 17 18 19 20 21 22
23 24 25 26 27 28 29
30 31
February
1 2 3 4 5

I have wrote code that has three functions, one to print the month, one to print the days in month, and one to find if it is a leap year or not. I have gotten up to the point where I can print the 12 months with a for loop, but how to print out the days in the format above.

This is my code.

#include <iostream>
using namespace std;
void printOneMonth(int month, int& dow, int year);
void daysInMonth(int month, int year, int& dim);
bool isLeapYear(int year);
int main(){
int year=0, dow, count;

[Code]...

I have this project, The problem is I have most of the code written, I am just having trouble setting it up correctly and placing it correctly. My code is rather long but as I said I know this is the longer and harder way to go about this.

//This program will be used to find out the day of the year
#include <iostream>
int month, day, year;
bool isALeapYear(int year) {
//Check if the year is divisible by 4 or is divisible by 400

C :: Program That Determine Day Number In A Year For A Date?

Oct 21, 2013

Write a program that determines the day number (1 to 366) in a year for a date that is provided as input data. As an example, January 1st, 1994, is day 1. December 31, 1993, is day 365. December 31, 1996 is day 366, since 1996 is a leap year. A year is a leap year if it is divisible by four, except that any year divisible by 100 is a leap year only if it is divisible by 40. Your program should accept the month, day, and year as integers. Include a function leap that returns 1 if called with a leap year, 0 otherwise. Extend the requested solution so that your program continues to prompt the user for new dates until a negative year is entered. This is what I have so far.

Code:
#include <stdio.h>
#include <stdbool.h>
int main(void) {

int d,m,y;
int days=0;
int k;

[Code] .....

I am unsure how to make this a loop so that it keeps asking for dates?

C :: Program To Calculate Business Days In A Year

Nov 11, 2014

I need to make a program to calculate the business days (Monday-Friday) in a year in C. As example:

Input
2026
Output
261

I need to consider that the year could be a leap year and that every year can start with a different day. My Problem is that i dont know how to implement the right number of business days in C. I wrote down the business days in Excel for 2010-2040. I cant see any system behind it, some years have 261 business days, some have 260 or 262 but in no order.

My program asks me to write a C++ program that generates a random number between 1-100, and lets the user guess the number until he/she guesses correctly.

I have every thing done but my loop will not end. I know I have to "update" the loop to end it but I don't know what that means.

C :: Program That Will Generate But Not Display Three-digit Target Number

Oct 6, 2014

Write a program that will generate, but not display, a three-digit "target" number that has three distinct digits. (Hint: use random number generator.) Then, input a maximum of ten user guesses and for each guess, output the number of hits and matches in the guess. Stop when the user guesses the number or runs out of guesses. For example, if the target is 427, the guess 207 has one hit (7) and one match (2).

C :: Program To Generate A List Of Powers Of 3 - Decimal Places?

Sep 23, 2014

So my assignment requires us to write a C program to generate a list of powers of 3 where each output line lists three numbers: k 3k 3‐k

It should look like this (just pretend all the numbers are lined up in their respective columns)

1 0 1.0
3 1 0.333333343
9 2 0.111111112
27 3 0.037037037
81 4 0.012345679
243 5 0.004115226
729 6 0.001371742
2187 7 0.000457247
6561 8 0.000152416
19683 9 0.000050805

This is what I keep getting:

1 0 1.000000000
3 1 0.333333343
9 2 0.111111112
27 3 0.037037037
81 4 0.012345679
243 5 0.004115226
729 6 0.001371742
2187 7 0.000457247
6561 8 0.000152416
19683 9 0.000050805

My input:

Code:
#include <stdio.h>
#include <stdlib.h>
void powers(void) {
int i=0;
int n=9;
int x=1;
float h=1;

[Code] .....

Notice how I'm getting 1.000000000 for my first h value in my output whereas I should be getting 1.0. What am I doing wrong?

C++ :: Program To Generate Pairs Of RSA Keys Using Small Prime Numbers

May 21, 2012

I have been writing a program to generate pairs of RSA keys using small prime numbers. I have been using mpz_invert() to get a value for d for the private key. On small prime numbers it calculates the correct value, but on larger primes it calculates incorrect values.

I'm assuming there must be an upper limit to the values the mpz_invert() function can handle? If so, what is this limit to avoid erroneous values?
