C++ :: How To Let The User To Modify The Counts
Apr 7, 2013
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 <fstream>
#include <algorithm>
#include <stdio.h>
#include <string>
#include <string.h>
#include <cmath>
#include <iomanip>
#include <iostream>
#include <cstdlib>
using namespace std;
#define ARRAY_SIZE 200

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

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);
} }

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;
}

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) {

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>

Write a program that opens a file and counts the whitespace-separated words in that file.?
My code that i wrote for this example is as follows...
#include <iostream>
using namespace std;
#include <iostream>
#include <string>
#include <fstream>
int main() {
string filename = "Question 1.cpp"; // File name goes in here
[Code] ....
Is this correct or am i missing something?

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.?

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.

I have a std::vector<int> and I want to modify subset of the elements. I thought I might be able to use:
std::vector<int> a = { 1,2,3,4,5,6,7,8,9 };
std::vector<int> b(&a[3],&a[7]);
for(auto& each : b) {
each++;
}
for(auto& each : a) {
std::cout << each << "
";
}
but that didn't work. The elements of 'a' retain their original values. Then, I thought, "Ooo, maybe I could make 'b' a reference." Nope. What approach would be to access a subset of a vector for potential alteration?

I'm trying to modify a library of a code and do not know exactly how to do it.I'm modifying the .cpp file and I know (as I have read on the internet) that I should compile it to obtain the .a file, because the main.cpp uses the .a file.I have written in the terminal the following command (founded on the internet):gcc -o analysis.hpp -c analysis.cpp but I still get an error.

My problem is that I have to modify only some specific details in a txt file (actually it is a wrl file but it can be considered as a txt file). There is a lot of text there but I just need to modify the point coordinates and leave the rest of the text as it is. Reading the "sample file" at some stage we will see some blocks that look like the below:
coord Coordinate {
point [
# bottom
-1.0 -1.0 1.0, #vertex 0
1.0 -1.0 1.0, #vertex 1
[Code] ....
where the numbers are (X,Y,Z) coordinates. What I have to do is to change those figures for (X,0,sqrt(X^2+Z^2)) points. Therefore the expected result (test file) will be as follows:
coord Coordinate {
point [
# bottom
-1.0 0.0 1.4142, #vertex 0
1.0 0.0 1.4142, #vertex 1
[Code] .....
So in my opinion it can be good to have two files: sample.txt and test.txt where the sample file will never be modified whereas the test.txt will be the same as sample.txt but including the modifications as explained above. The idea can be to read the sample.txt, store the info and then start copying each line in the test file until we get to the points coordinates (which needs to be modified) and continuying with this process until the next set of coordinates.
The problem is that I do not know how to change x,y,z coordinates from the sample.txt to (X,0,sqrt(X^2+Z^2)) and to copy them in the test.txt. Please see some code below and the sample.txt file attached.

I have made a Student record system in c++ using the concept of linked list. The program will take the student id, name and marks for 3 different exams. Then it will calculate the aggregate percentage based on those exams marks and display the relevant message according to the aggregate percentage. All is going well. But there is only one problem. When I modify the student record especially the marks, it doesn't change the aggregate percentage of that specific record. It shows the old one. Similarly the relevant message doesn't change too.
Code:
struct student{
int id;
char name[MAX];
string status;
double aggr;
int matric_marks, inter_marks, entryTest_marks;

class MyOwner {
...
int m_count;
bool b_locked;
};
[Code] ....
I am using an API where I create many MyObjects on the heap, and the API uses a separate thread to send messages to each object. Each MyObject contains a pointer to MyOwner.
Suppose I want to keep a count of all messages received in all MyObjects: How can I do this in a thread safe way?
I am assuming that the code I have written above will not be safe--at the very least it seems that it would potentially miss message counts when it was locked--not the worse case scenario for me. I am most concerned about not causing the application to crash.

void add(const string text, T value) {
cont.push_back(text, value);
} int ex = 1;
add("Example", ex);
ex = 12;
for(int i = 0; i < cont.count(); i++)

I have a N queens (actually 8 queens to be specific) program that accepts the numbers in order by row. I need to get it so it accepts the numbers in order by column. At first glance I thought it was just one space different, but it turned out not to be and how to get the one space difference in there. My current code (which I'm aware isn't doing the column accepting right) is:
Code:
#include <iostream>
using namespace std;
int main() {
int board[8];
cout << "Enter the columns containing queens, in order by column: ";
for(int i = 0; i < 8; ++i) {
cin >> board[i];
[Code]...
What the output should be:
Code:
Enter the rows containing queens, in order by column:
7
6
5
3
4
2
1
0
.......Q
......Q.
.....Q..
...Q....
....Q...
..Q.....

What it is:
Code:

I've initialized a character array in my main, and passed it onto one of my functions convertToPostfix(char infix[], char postfix[]). It isn't a constant read only array (constant char*) ive explicitly initialized it to char postfix[] = "";
Code:
if ((nextChar > 47) && (nextChar < 58)){ //if its a digit
postfix[++postfixIndex] = nextChar;
while (infix[i + 1] > 47 && infix[i + 1] < 58){
nextChar = infix[++i];
postfix[++postfixIndex]=nextChar;//segmentation fault when assigning from infix to postfix**

I derived a class from CRecentFileList in order to set the number of displayed chars for MRU.
The problem is that if I open the app with 256 set for this number (it is read from .ini file) the display is correct. But after I change it to 10 for e.g., File menu width remains unchanged altghough MRU are correctly displayed on 10 (or at least file name lenghts) chars.
how can I tell to the menu to shrink to actual width?
