C++ :: Ignoring Comment Line Beginning With Hash Sign
May 16, 2013
My program had a requirement to ignore an input beginning with a # sign. The input is entered by user from keyboard. I wanted to know how to use cin.ignore to achieve this.
#include <iostream>
#include <algorithm>
#include <string>
#include <iomanip>
#include <limits>
#include <stdio.h>
using namespace std;
[Code] ....
The output:
Enter the string
# Comment
This is the # comment string.
Answer:
This is the string.

I am building a template for CodeBlocks, which pre-write some includes, the main skull and a header.
This header looks like that :
/**
* @Author Me
* @Description Brief description
* @Date ??
*/
I would like to put the current Date, just after the line @Date, is-it possible ? And if yes, it-is possible to put a field @FileName which copy the filename into the comment ?

''' <VariableName> loadApp </VariableName>
''' <VariableDiscription> loads the Application </VariableDiscription>
''' <Author> Author Name </Author>
''' <LastModifiedOn> 01/09/2012 </LastModifiedOn>
[Code] .....
Now I would like to extract the data inside these comment tags and insert into excel sheet. Need to extract the comments in the xml tags shown in the able format? For example I want the value inside the <Autor> tag.

I am a math teacher who is taking a programming class. My district wants to incorporate some programming tasks into the high school math curricula. I am working on a project to calculate a final grade and output this along with a comment to a text file. The following data is the input that I created:
3 300 100 100 100 .15
4 400 100 98 94 92 .45
3 300 98 100 92 .40
The final grade output results in gibberish.

I'm using a Windows.System.Forms.Webbrowser and the document text contains
...<style type="text/css">
Table {
page-break-after: always;
}
table:last-of-type {
page-break-after: auto
}
</style>...
As soon as call ShowPrintPreviewDialog() to show the print preview dialog, it appears to be ignoring
table:table:last-of-type
because the last page in the document is blank.

How I can manipulate certain strings. This program here is supposed to randomly scramble any word/sentence input. However, I notice that even the empty spaces get moved; is there any way to stop that from happening? I would want the empty spaces to stay in their input positions.
#include <iostream>
#include <string.h>
#include <ctime>
#include <cstdlib>
#include <fstream>
#include <string>
using namespace std;

Now, I have an assignment in which I am to accept arguments from the command line and copy them into a cstring and display said cstring unmolested. Then I should store it into another cstring but ignore all punctuation, spaces and capital letters. Like this:
./a5 Marge lets Norah see Sharon's telegram
As is: Marge lets Norah see Sharon's telegram
---->: margeletsnorahseesharonstelegram
<----: margeletsnorahseesharonstelegram
Sequence entered is a palindrome
=======================================================
Finally I am to chaeck to see if it is a palindrome. Most of it works and if no spaces are entered nor punctuation it works. However, punctuation causes it to malfunction.
char *FormSeqProc (int argc, char *argv[], char seqAsIs[]) {
int len = 0,
n = 0;
for (int p = 1; p < argc; ++p) {
len += strlen(argv[p]);

I need to ignore negative values in an array, but not exit the function.
For example if the user enters:
1,2,3,4,-1,-2,0
the array would be
[1,2,3,4]
Is there a way to ignore these values?

My random number generator isn't working properly. It seems to be ignoring my conditions when it compiles and I enter the input. The program is supposed to accomplish the following.
1. Let the user input how many digits he or she would like to have in the random numbers.
2. Let the user type in how many of the numbers that he or she wants.
3. It will then generate the numbers.
4. It will display the minimum or maximum number it can be with the number of digits the user entered. And display the number of numbers that the user wanted. It also is supposed to check and output only up to the max of that digit range.
so if someone entered they wanted a digit of 1(1-9) but said they wanted 300 numbers it would only output 9
Example:
the user says that she would like 3 digits to be in the numbers generated. So it will output numbers between 100 and 999. then the user says that they would like only 3 random numbers. So it will output three random numbers in between 100 and 999. Also all of the numbers need to be unique so they can't output more then one of the same number.
I am not sure why but it ignores my conditions. Ill type that I want 7 but it just outputs a bunch of random numbers. it dosen't stay in the ranges.
Class file.
Code:
#include "stdafx.h"
#include <fstream>
#include <iomanip>
#include <iostream>
#include <string>
#include <conio.h>
#include "TargetGen.h"
using namespace std;

Assuming that we have the string :
Code:
***HELLO&SIR. & and * is the delimiters.
My question is how strtok will work in the beginning?
According to this to determine the beginning and the end of a token, the function first scans from the starting location for the first character not contained in delimiters (which becomes the beginning of the token). And then scans starting from this beginning of the token for the first character contained in delimiters, which becomes the end of the token. The scan also stops if the terminating null character is found.
This end of the token is automatically replaced by a null-character, and the beginning of the token is returned by the function. strtok will replace the first * with '' and the next call will start from the second * puts '' there and again the same with the third * ?

So I have to make a program that allows the user to enter both positive and negative numbers and the program is suppose to calculate the sum of only the positive values while ignoring the negative values. Also it is to be a sentinel-controlled loop with a number ending the set of values.

I am writing another program and I cannot find for the life of me how to loop the program back to the start of a function.
Code:
#include <stdio.h>
#include <stdlib.h>
int main(void) {
int choice;
char band1, band2, band3, band4;
printf ("This program calculates the resistor value based on the colours of the wire.
(enter the integer near the command)
");
printf ("What would you like to do?
[Code].....
This is my current iteration of the program. Obviously, I haven't finished writing the case 1 of the first switch, but for the other ones. I thought that return main would cause the program to loop back to the beginning after executing the case, but I see that it is not the case (pun not intended). Anyways, what would I have to insert to cause the program to loop again (other than for case 3)? And another question, why is it that in scanf in the first case, the program only accepts two characters before finishing?

I'm writing a program that converts hex to letters and writes the letters to a file.To write I'm currently using ofstream("output.txt" ios::app)But the issue with this is, is that everytime I run the program, it appends and doesn't write from the beginning of the text file.So what I want to know is, how do I clear the contents of a text file, before writing to it?

So I'm making my first program w/ C++ and its a game guessing game. I've learned how to use booleans, chars, strings, if/else, loops, and input. Anything past that I dont know. I've gotten my game to work properly except for the fact that when you guess incorrectly, the program closes. I want the program to go to the beginning of the program again so the user can restart. So far i've gotten the loop to beginning thing to work but not well. It'll only repeat twice before closing again and it'll say the user got the wrong answer even if it was correct. Here's my code
#include <iostream>
#include <string>
#include <random>
#include<ctime>
using namespace std;
int game(){
string playerName;
int guess;

I am currently having problems creating a loop that will allow my user to choose to return to the beginning of the program or quit.
#include <iostream>
using namespace std;
int main() {
int j;
do {float a;
cout << "+----Welcome to Basic Operations----+
| Select Your Operation |
[Code] .....
I have not yet finished designing the interface for a couple of the operations, but right now i am hung up on trying to return to the beginning. I believe it is because the j was defined inside do and isn't carried out of the do statement for while.

I have a problem with this function that adds a new value to the hash table or updates its data if the value already exists:
Code:
int tab_add(tab_disp *td, const object *value) the function should return:
TABDISP_OK if the value is correctly added, or TABDISP_ERROR if memory error, or TABDISP_INVALID if pointer td = NULL
The type of structure I am using is the following:
Code:
typedef struct {
char key[25];
char value[100];
} object;

Code: I have these two columns.
ID Group
0 2
1 2
2 3
3 4
4 4
5 4
6 4
7 4 Code: I want to store ID values on the bases of same Group, like we do in Hash table (key, value) .
Group ID
2 0,1
3 2
4 3,4,5,6,7
so when i said key 2 it will give me 0,1. how can i do it. As first i thought that i can use array of array but then how i can store the value of key. Now I am thinking of hash but i don't know how I will store and retrieve these values.
