C :: Euler Project - Number Letter Counts
Apr 30, 2013
I am working on Euler Project exercise number 17. Here is the problem from the website.
"If the numbers 1 to 5 are written out in words: one, two, three, four, five, then there are 3 + 3 + 5 + 4 + 4 = 19 letters used in total.If all the numbers from 1 to 1000 (one thousand) inclusive were written out in words, how many letters would be used?"
Code:
#include <stdio.h>
#include <string.h>
#define LENGTHOFHUNDRED 7
#define LENGTHOFONETHOUSAND 11
#define NUMSTART 1
#define NUMEND 1000

I need to create a program that asks the user for the filename, then counts the number of occurrence of each letter in that file.
Ex. if the file contains
Absacsac
asdasda
Output will be
a = 6
b = 1
c = 2
.
.
.
z = 0
This has been my program so far:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
#include <cstdlib>
void countingFunction(string sentence) {

I am supposed to have a loop that terminates when the difference between two successive values of 'e' differ by less than 0.0000001 (6 zeroes). So far I have written this much of the code:
#include <stdio.h>
double eCalc(int terms, double e);
int main() {
int dummy;
int terms;
double e;
[Code] ...
It will not even run. Compiler code errors are as such:
error C4700: uninitialized local variable 'e' used

I started to learn programming through this site two weeks or so ago. I've got a book with exercices and so on, and one of them involves calculating e within a tolerance given by the user.
The formula for calculating e is the summation of 1+(1/i!), where i -> n.
So, here's the code and I'll explain the problem below:
Code:
#include <stdio.h>
int main()
{
float error;
float terme;
float sumatori = 0;
int cicle_euler = 1;
int factorial;
[Code]...
For some reason, when I set factorial to cicle_factorial, factorial remains 0, which I find puzzling; the program always halts when 1 + sumatori is 2.0 no matter what error is.
This must be a common problem and I suspect it has to do with some distinction between variables inside a loop and variables outside it, but as I lack technical vocabulary I can't seem to find anything on Google.

I am trying to write a code that counts the number of words in a string that end with ng.
I started with this but this just checks the end of the string. I need it to check everyword in the string and also count them up.
int main() {
string s;
cout << " enter string ";
getline(cin, s);
string end;
end = s.substr(s.length()-2, 2);
cout << end;
cout << endl;
return 0;
}

So I need to make a program that counts the number of words, lines, and vowels in a program. Punctuation and white spaces are not counted in any of the counts. I have this so far and the words, and lines work and are correct but I can't seem to get the vowel count to work.
#include <iostream>
#include <fstream>
#include <cmath>
#include <cstdlib>
#include <string>
[Code]....

I have an issue with a database call. I've got a database call that counts the number of entries in the database:
private static Int32 dbCount() {
SqlCommand cmd = new SqlCommand("SELECT COUNT (*) FROM Employees", conn);
conn.Open();
Int32 count = (Int32)cmd.ExecuteScalar();
conn.Close();
return count;
}
Afterwards I'm using this as a check throughout my application:
if (dbCount > 0) {
// do something
}
When I execute this code I'm getting the following error: "Operator '>' cannot be applied to operands of type 'method group' and 'int'"
So I'm guessing it has something to do with the cast of the dbCount-object but I don't understand why as I already stated that the count-object to be an Int32.

In C how can I initialize a variable that is not a letter or number? For example with a number I can :
Code:
int i = 5;
for ( i = 0; i <=5; i++ );
printf( "%d", i ) This would display a row of 5's
but what if I wanted to display a row of -----? What I am trying to do is read in a simple txt file, around the file I want ----1----2-----3 ect ect on the top ----a----b-----c down the side Then I want to be able to change the file at lets say position c2 and save it. This is the early stages of my attempt to set up a editable table.

For example if I have typed 0xFF (a literal hex number that represents the value 255 for Unsigned Char or -1 for Signed Char) in part of my program. That 0xFF is treated as a Char not an Int, because the value is within the range supported by Char, the C compiler always tries to use the smallest datatype possible for the number that is needed for a literal value like this.
Unfortunately because Signed Char is the default Char type, 0xFF is translated into -1. I am wanting to use it to represent 255. So I'm trying to tell the compiler that 0xFF should be interpreted as either an Int or an Unsigned Char. How do I do this?
I already tried typing it with the magic letter "I", like this: 0xFFI
But that didn't work. What is the correct way to do this?

I have one string from user. Let say,
"The deviceId is 2"....but user also can give input like this..
"The deviceId is a".
I just need to know how to differentiate a word/letter and number in the string.

So I have to write a program to calculate a grade letter into a number.
Letter grades are A, B, C, D, and F, possibly followed by + or –. Their numeric values are 4, 3, 2, 1, and 0. There is no F+ or F–. A + increases the numeric value by 0.3, a – decreases it by 0.3. If the letter grade is illegal (such as "Z"), then your output should be "INVALID LETTER GRADE"; If the combination is illegal (such as "A+" or "F-") then your output should be "INVALID GRADE COMBINATION"
Also the code should look like this
Enter your letter grade: C+
Grade value is [2.3]
// Input
cout << "Enter your letter grade: ";
string s;
cin >> s;
[Code].....

Dont know how to replace each letter as s number ... this is the question i was given ...
In cryptarithmetic puzzles, mathematical equations are written using letters. Each letter can be a digit from 0 to 9, but no two letters can be the same. Here is a sample problem:
SEND + MORE = MONEY
A solution to the puzzle is S = 9, R = 8, O = 0, M = 1, Y = 2, E = 5, N = 6, D = 7.
Write a program that finds a solution to the cryptarithmetic puzzle of the following:
TOO + TOO + TOO + TOO = GOOD
The simplest technique is to use a nested loop for each unique letter (in this case T, O, G, D). The loops would systematically assign the digits from 0 to 9 to each letter. For example, it might first try T=0,O=0,G=0,D=0, thenT=0,O=0, G = 0, D = 1, then T = 0, O = 0, G = 0, D = 2, etc., up to T = 9, O = 9, G = 9, D = 9. In the loop body, test that each variable is unique and that the equation is satisfied. Output the values for the letters that satisfy the equation.

I am trying to fill an array with blank spaces and instead i get the number 32 over and over, i think this is the ANSI code for that character. how do i get the character itself?
char values[max];
for(o=0;o<=max;o++)
{
values[o]=' ';
printf("%2d ", values[o]);
}
printf("
");

I have a string - a whole sentence that I want to assign a number to each letter, space, comma and period etc. So all "A's" will have the same number, all "B's" will have another number etc. I don't want to use the ASCII numbers because they all need to be sequential and some of the punctuation isn't. I have put the string into a char array to separate each character out and was thinking about running it through a loop with if statements for each letter and assigning numbers there and then saving the numbers in the order they appear into a list as a string but I keep coming up with errors so I don't know how to do it or if there is a better way to accomplish what I'm trying to do.

I have been given to do a simple ATM project which is containing of getting a number of notes in the ATM (100, 500, 1000). Get the withdrawal of money and show the number of note. Here what i got so far. I may need to use a loop but I am not sure how to put it into this.
#include <stdio.h>
#include <conio.h>
int main() {
int a=10, b=10, c=10;
int q;
[Code] ....
But the problem is i don't know how to make the code continue with the process with the amount of notes that is left from the previous input. The program will just stop but i really want it to be able to input new withdrawal amount so that it can decrease the note each time i withdrawal the money.

I am having one issue with my project. We are making a game of Nim code.I'm 99% done with it, i worked hard on it and i feel like i did a good job, however my project is not displaying the matches i want. For example, it display's the inital number of them 23. But once the first player subtracts a number, it doesn't display matches for player 2, just the number of matches remaining. Then as i keep running the program the same thing happens. This is what it's supposed to
output:
"Input/Output sample
WELCOME TO NIM
------- -- ---
Enter the starting player's name (no spaces)-->John
Enter the second player's name (no spaces)-->Mary
There are 23 matches.
ooooooooooooooooooooooo
|||||||||||||||||||||||
Player John please enter the number of matches to remove-->2
There are 21 matches.
ooooooooooooooooooooo
|||||||||||||||||||||
Player Mary please enter the number of matches to remove-->3
There are 18 matches.
oooooooooooooooooo
||||||||||||||||||
Player John please enter the number of matches to remove-->1 "
This is entire code.
#include <iostream>
#include <string>
using namespace std;
int main() {
// Holds variables.
[Code] ....
I will attach my code as well.ProjectNim.cpp

i'm having trouble with my c programming assignment. i'm trying to convert a number grade to a letter grade. I'm trying to Write a function (called: numToLetter) that takes as input a number from 0 to 100 and returns a character ( a single character ), based on the following: if the number is between 60 and 70 return Dif the number is greater than 90 return Aif the number is between 70 and 80 return Cif the number is between 0 and 60 return Fif the number is between 80 and 90, return B and i need to use the return statements to call the function like for example:
if (a > 90) return ('A');
elseif (a > 80)
return ('B');
elseif (a > 70)
return ('C'); else
return ('F');
how do if write my code with this function?

I have a project which does a specific thing, like an open file dialog.
I would like to open it in a different project on a click of a button.
Also, It has a different namespace.
I'm guessing that it would involve a "using" statement to add the namespace And I will have to add reference to an *.exe or *.dll -> I'll have to look up how to make a *.dll, I know where the *.exe file is.
I have searched for a different things on Google, but I don't think that I am looking for the correct phrase (which is always frustrating...)

I have a very simple application that I want to display counts on a textbox. The problem is that the counter freezes the entire program and it only shows the last count. So I want to count from 0 to 100 incrementally with a delay of 250ms per count and display as it counts on the text box. 0...1...2...3......100 etc
Code:
private void count() {
for (int i = 0; i < 101; i++) {
textBox3.Text = i.ToString();
Thread.Sleep(50);
} }

After the data is in the array, prompt the user to modify the array by inputting a species name and a count. If the species is not in the array, print a message indicating this and add the species to the end of the array. If the species is in the array, change the count in the array to the new count. Allow the user to input any number of changes.
This is what I have so far:
//Description of program:Manages a list of bird species and counts stored in an array of structs.

#include <algorithm>
#include <stdio.h>
#include <string>
#include <string.h>

So I am writing a program that counts the letters of 3 lines of input from the user. I am using a 3 x 80 character array as the "notepad". Upper and lower case characters are incremented on the same counter array.
Code:
/*Letters in a string*/
#include <stdio.h>

#include <ctype.h>
void countAlphabet(char *);
/*Character counting array*/
int alphabet[26] = {0};

Question is : Write a program that opens a file and counts the whitespace-separated words in that file.?
my answer is :
#include <iostream>
using namespace std;
#include <iostream>
#include <string>
#include <fstream>
int main() {
string filename = "Question 1.cpp"; // File name goes in here
[Code] ....
Now I am not sure if im suppose to get a msg saying : The file "Question 1.cpp" has 0 words.
im wondering is the question that im being asked, asking me to input a string of words and then the compiler when it builds and runs the program counts the word spaces.?
