C :: Write A Program To Display Class Schedule To User
Apr 20, 2014
I'm new to coding, and I have to write a program to display a class schedule to the user (the classes are entered into the program in strings like this:
Code:
course Calculus3 = {80934,"MATH",11,"Calculus 3","Edward Turner","M,W",950,1100}; )
in the format of an excel file (the user picks the classes they want to have) that then displays the course title and professor in the correct cell corresponding to the day/time the class meets. I've been googling it, and from what I've read, I think I need to use a csv file, but I don't know how to input the data into the file. I know the general format for how data is entered, but I don't know how to write it into a specific file or if I even have to (we covered txt files very briefly in my class, but never touched csv files).

SO Im supposed to write a program that uses arrays to calculate the sum and display it. I keep getting the error that says the sum has to be initialized.
#include <iostream>
using namespace std;
//Function prototype
int sumArray(int);
const int NUM_ELEMENTS = 5;

I am trying to make a program with a Cartesian class that allows the user to enter 2 coordinates and displays these coordinates. When I try to compile it, I get a message saying the x and y in x=c and y=d don't name a type. How can I fix this? Also, how would I go about inserting an assignment function that assigns the values of coord1 to coord2?
Code:
#include <iostream>
#include <istream>
#include <ostream>
using namespace std;
class Cartesian {
private:
double x;
double y;

So I am trying to write a program that asks the user for a name. If the user enter the right name the program ends but if the user were to enter the wrong name the program would enter a loop prompting the user to re-enter the name. However I am not able to get the program to work!

So I'm trying to create a program that allows one to read/write on to output.txt. I though I had everything set up right, but its only writing one word to the text file. Heres the code.
#include "stdafx.h"
#include <iostream> //Needed for User Input
#include <fstream> //needed for ofstream
#include <string> // needed for strings
#include <windows.h> //needed for Sleep
#include <cstdlib> //Needed for return EXIT_SUCCESS;
using namespace std;
int main() {
ofstream outputfile; //allows to read and write to files

If I type Puppies Are Cute and go to output.txt, the only thing written in the text file is Puppies.

I'm trying to write a program where it asks the user for a file name.
If that file exists, the it will open the file and then read it and print the information in the file.
However, if the user enters a file name that does not exist, the user will have 2 more tries (for a total of 3 tries) to get the correct name of the file.
I am close to getting it. What I have now just won't go through the loop to validate if the input matches an existing file. It goes straight to the printing of what is in the file. If the file doesn't exist, it prints: "Found your file..Opening..processing...Total keys found = 0."
So, my question, what am I doing wrong that it won't go through the loop properly?
#include<iostream>
#include<iomanip>
#include<fstream>
#include<string>
using namespace std;
int main() {
bool fileFound = false;

I need to write a program to make the user input some text, and the first letter of each word has to be uppercase. (have to use while loops)
So for example lets say the user inputs:
i lOvE pRoGrAmMiNg
The output needs to be:
I Love Programming
Code: int main()
{
char c, lower_c;
printf("Enter Text");
while (c != '' && c >= 0)
{
if (c >= 'A' && c <= 'Z')
lower_c = c + 32;
else
lower_c = c;
[Code]...
I have started this code by making the letters lowercase (I don't know if this was the right way to approach this, ). I am not sure how proceed after this step, the step of making the first letter uppercase. (PS for the program, loops should be while loops)

Write a program that prompts the user to enter an integer and then displays that integer as a product of its primes and if it is a prime then it should say so? Above is the question I have been given
#include <iostream>
#include <vector>
using namespace std;
int main () {
int num, result;
cout << "Enter A Number " << endl;
system ("pause");
return 0;
}
This is what I have so far, do I have to use a for loop, a while loop or a do loop,

Write a program that asks the user to enter a student’s grades on four exams. The program should display the four grades and the average of the four grades,rounded to the nearest tenth. To add the grades, use a variable called total_grade, which you should initialize to zero.As the program prompts for and obtains each grade, add the grade to total_grade using the += operator.

So I need to write a program which tells the user if the number they input is prime or not. I have done so and included the code below. My problem is that I need to allow the user to input if they want to enter another number after the first one using y or n and I am having trouble figure it out.
#include <cstdlib>
#include <iostream>
using namespace std;

Write a program that prompts the user to enter an item#, the program should determine if the item is in the file and print the price of the corresponding item. If the item is not in the file an error message should be printed.
All I have so far is
string item_no=0;
cout<<"Enter a item#";
getline(cin,item_no);
if stream openData;
I need to finish the rest in pseudo code

I'm trying to write a program where the user will keep entering data until pressing control + D. Then the it will display the mean, smallest number, and largest number.
Here are three samples of my program running.
Sample 1
Enter the price for stock 1: $ 10
Enter the price for stock 2: $ 1.555
Enter the price for stock 3: $ 3.648
[Code].....
As you can see in Sample 1, the program runs correctly. The largest number was 20 and the lowest number was 1.555. But in Sample 2, the program shows min as 15.500, where it should be showing 15.000 and Sample 3, the program shows min as 110.000 when it should be showing 55.564.
Here's the code.
#include <iostream>
#include <iomanip>
using namespace std;
[Code].....

I have to write a program where the user will input integer numbers. How many numbers they enter is unknown, therefor you should use a repetition structure for the input. When the user is done, they will enter -1 to exit.
Create a dynamic array if the size=2( the initial size must be 2) Repeat until user enters -1.
I have to do this without using vectors.
This is what i have, I cannot figure out what to put in main. I was thinking of a do-while?
Code:
#include <iostream>
using namespace std;
void resize(int *[], int);
int main() {
int *listDyn;
int size=2;

I am writing a music program that will read (from a separate file) a guitar chord and display it to the the user. The format of the separate text file is as follows:
A
|--0--|
|--2--|
|--2--|
|--2--|
|--0--|
|--x--|
B
|--2--|
|--4--|
|--4--|
|--4--|
|--2--|
|--x--|
C
|--0--|
|--1--|
|--0--|
|--2--|
|--3--|
|--3--|
etc...
I want the user to be able to search for a specific chord in the file and how I can make that happen.
#include <iostream>
#include <fstream>
#include <string>
#include <cstdlib>
using namespace std;

I am trying to write a program for class that reads from an input file the month, year & total collected. I am using notepad for the input file.
This is what the notepad file looks like
-----------------------------------
March 2013 63924.62
Why does it give me random numbers in the output rather than what the notepad has?
Also, the outfile is completely blank.
#include <iostream>
#include <iomanip>
#include <fstream>

I am writing a program for a class where the user enters their age, how much money they have, and their full name. I know that I have to use the getline method to get the user's full name, and I know that I have to use cin.ignore() before that code, but i'm not sure why I have to use cin.ignore()?

I am new to this area and have the requirement like:
1) A running process wants to send message based on event arrival.
2)the process checks if event is critical
3)if critical then it has to send message immediately ,else send after time t.
4) The process is continuously process the events . so once it knows the event is not critical and has to send message later it has to proceed with its normal operation.. only when time 't" comes it has to come and send message.

Write a class definition for a Fraction class. Its member fields are num and den, both of type int. The constructor builds the default fraction 1/1. It has the following operations:
void plusEquals(Fraction second);
//Adds the second fraction to this fraction like the operator += void minusEquals (Fraction second);
//Subtracts the second fraction from this fraction void timesEquals (Fraction second);
//Divides this fraction by the second fraction void dividesEquals (Fraction second);
// Divides this fraction by the second fraction void reduce();
// Reduces this fraction to lowest terms double todecimal();
//returns the decimal value of this fraction void scan(istream&);
//scans a fraction written with a slash as in ¾ void print(ostream&);
//prints a fraction using a slash Fraction();
//constructs a default fraction with denominator 1, numerator 0 Fraction(int n, int d); //constructs a fraction given value for num and den
2. Write a menu-driven driver program designed to allow thorough testing of your Fraction class.

I'm trying to write this c++ programe:
Write a password prompt that gives a user only a certain number of password entry attempts, so that the user cannot easily write a password cracker.
Using FOR Loop. I know this can be easily done using while loop. But I want to know how to do it with for loop aswell.
Here is what I have so far:
Code:
#include <iostream>
#include <string>
using namespace std;
int main ()
[Code] ....
I don't see where the problem is.. The program just executes and does nothing.

So I've been turning my programs into classes and I run into errors.
So this program is supposed to allow the user to open the file and either read or write to it.
I've omitted the read part from it as I want to attempt that on my own .
I get these compile errors:
fileclass.cpp:13: error: ISO C++ forbids declaration of ‘choice’ with no type
fileclass.cpp:21: error: ISO C++ forbids declaration of ‘choice’ with no type
fileclass.cpp: In member function ‘int file::choice()’:

A problem that lets the user enter any positive integer, but you do not have to check for this, and then calculates the sum of the digits and displays this to user. For example, if user enters 14503, the outputted sum of the digits would be 13.
Here is my program
#include <iostream>
int main(void) {
int integer, sum=0;
while(integer) {
sum += integer % 10;
integer /= 10;
} cout << "The sum of the integers numbers is " <<sum;
return 0;
}
