C++ :: Program To Check Whether Or Not A String Is Palindrome
May 20, 2013So I've been tasked with creating a program that checks to see whether or not a string is a palindrome. It has to remove whitespace, punctuation, and capitalization for obvious reasons. Getting some errors which I'm not sure how to correct.
On an unrelated note, while programming in the console, my cursor has turned into a gray box and replaces characters when typing, instead of pushing them forward, etc. How do I return it to normal?
#include <iostream>
#include <string>
#include <iomanip>
using namespace std;

C :: Check To See If String From Standard Input Is Alphanumeric Or Not?
Dec 25, 2014I'm trying to check to see if a string from standard input is alphanumeric or not. I feel as though there may be a function for this but...
Code:
for(test_pass = i; test_pass < i; i++){
if(test_pass[i] == ('1', '2', '3', '4', '5', '6', '7', '8', '9', '0'))
printf("Your password is alphanumeric!
");
}
The compiler wasn't too happy with this.
C/C++ :: String Variable - How To Check If Email Is Not Fake
Jun 4, 2014Ii made one string variable and called it email_confirm. I used cin to get the users email but i don't know to check if the email is real.(without being connected to the internet).
For example,in PHP you can use ereg() or eregi() to see if the email is real, I mean you can see how many characters the email_confirm is made off or how many characters is used after the @ or . is used. is there any functions for this?

C :: Code To Hit Database And Check File Size
Jan 13, 2015I have been given a task of checking the size of file in Linux machine using C Program. Below is what I came up with
Code:
#include <stdio.h>
void main(int argc, char **argv) {
FILE *fp;
char ch;
int size = 0;
[Code] .....
But Now I have been asked to modify this code in a way that instead of passing the file name as parameter, I have to make a database connection and fetch the value of the filename and location from the database table and check the size . My program has to repeat this process every ten minutes, which means every ten minutes my program has to hit the database, fetch the value and check the size in the file system.
I heard like I Have to create a Fork Call, and have the child instance run every ten minutes.

Visual C++ :: Check For File Existence - Function Will Fail Or Return Non-zero Value
Sep 21, 2013Just wonder is it possible that if the file exist, this function below will fail by returning non-zero value?
_access( INIFilename, 00 )
00 - check for Existence only
I noticed that sometimes if even the file exist, the function will fail or return non-zero value. So trying to find out and duplicate this error. It tends to happen intermittently. How can I find out what causing this error?
Code:
char INIFilename[256]="C: emp est.ini";
unsigned long Error = 0;
if( _access( INIFilename, 00 ) != 0 ) {
Error= GetLastError();
printf ("Failed to access INI file %s (%ul)", INIFilename, Error);

C++ :: Spell Checker - Check If Inputted Word Is In Dictionary File On Computer
Jul 31, 2013Over the last few days, I've been trying to implement a spell checker in c++ that checks if the inputted word is in the dictionary file on my computer. However, as I'm nearing completion of the project, I keep running into more and more errors, some of which I do not understand. My program is complete, albeit, with some minor bad practices (I hard coded a few things just to get the program up and running.For some reason, everything works well until I output spelling suggestions. I type in "mses" (attempting to spell mess) and it returns some strange characters. It does definitely recognize that there are two permutations that match words in the dictionary (however they are both mess due to the algorithm implemented), and I don't understand why? I will work on removing the duplicates after.

View 3 Replies View RelatedC :: Reading From A File And Skipping Lines To Find String In File
Nov 26, 2013Program background: Ticket Sales Details You will sell tickets in advance and at the door. Prices for buying in advance and at the door will be given. Also, the total number of tickets sold in advance will be given. Each guest will have a unique number. If there are n tickets sold in advance, then these guests will be numbered 0 through n-1. As the event starts, requests to buy tickets at the door may be made and these guests will be numbered sequentially, starting at the lowest unassigned number. The maximum number of guests will be 1000. The first line of the file contains the following three values, separated by spaces: Cost of the presales tickets (in dollars), Cost of the tickets at the door (in dollars), and the number of presale tickets. The first two values will be positive real numbers to two decimal places and the last will be a positive integer.
The second line of the file will contain one positive integer representing the number of auction items followed by a positive real value to two decimal places (at most) representing the minimum bid increment, in dollars. The first value is guaranteed to be 1000 or less and the second will be in between 1 and 50, inclusive.
The third line of the file will contain all the prices of the auction items, in dollars, separated by spaces, in order. Thus, the first price is the price of item 0, the next price is the price of item 1, and so on. These values will be real numbers represented to up to 2 decimal places.
The fourth line of the file will contain the three following positive integers pertaining to the raffle: the number of raffle tickets available, the cost of a raffle ticket in dollars, and the number of raffle prizes. (It's strange to have raffle tickets that don't cost a whole number of dollars.)
The fifth line of the file will contain each of the values of the raffle items, in dollars, separated by spaces, in order. Thus, the first price is the price if item 0, the next price is the price of item 1, and so on. These values will be real numbers with upto 2 decimal places.
The sixth line of the file will contain ten positive integers representing the number of each of the drinks 0 through 9, in order, that are in stock.
The seventh line of the file will contain ten positive real numbers with upto 2 decimal places representing the price of each of the drinks 0 through 9, in order.
The eighth line of the file will contain a single positive integer, numEvents, representing the number of events that occur at the charity ball. These events are split into two groups: actions by guests at the ball and awards given (raffle, auction, person, totalrevenue). All of the actions precede all of the awards. You will produce exactly one line of output for each event described. Here are the formats of each event that could occur:
If a patron buys a ticket at the door, a command will be on a line by itself:
BUY TICKET k
where k is a positive integer indicating the number of tickets bought at the door. These guests will be numbered as previously mentioned. You are guaranteed that the total number of tickets bought, including presales, will not exceed 1000. This is what I have so far and I cannot figure out why it wont calculate the total revenue. I am not completely sure if it is even accessing the if statement in main.
Code:
#include <stdio.h> #include <stdlib.h>
#include <string.h>
#define N 1000

C++ :: UTF-8 File To String

So, string szq is fine, except, that it contains a at the beginning of the string. How is that, and, what can I do to get rid of it?

C :: Search File For String
Aug 22, 2014I should state that I am recently new to C programming. I have dabbled with Python in the past, but nothing formal. I am taking a C programming class, but it is an introductory course. As such, the instructor is moving extremely slow through the material.
With this program, I am trying to search a given text file (line-by-line) for user-submitted data. I then want to be able to store which line that data was found on. The program runs, but it always results in "Sorry, couldn't find a match." Even if it shouldn't.
Code:
#include <stdio.h>
#include <conio.h>
#include <string.h>
#include <stdlib.h>
}
[code]...
I should probably explain my overall goal with this program.I would like to write a program that will calculate the molecular weight of a compound. I expect the user entered molecular compound to be something like this: CH3COOH (An equivalent entry could be C2H4O2)Also, it needs to be case sensitive because the chemical formulas are case sensitive.
The output will be "The molecular weight of CH3COOH is xxx.xxxxx grams".I have two text files as well. One contains a list of all chemical symbols, and the second is a list of all atomic weights in the same order as the first. I want to place the user inputted data into an array, then search for each element of that array in the chemical symbol text file. It will show which line it was found on, then I can use that line to grab the atomic weight from the second text file.
