C Sharp :: Remove Specific Char In String
Jul 5, 2013int index = -1;
string NewStr = null;
char[] lower = {'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'};
char[] upper = {'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'};
foreach (char c in str)
[Code]....
The code above loops through a string and for each character checks to see if it is a lower case character, then checks to see if it an upper case. It then removes it if it is. Leaving only the numbers.
However, it reuses the same string the entire time, never updating the string so it always finds the same (first) character.
C :: Best Way To Store Input String Into Char
Sep 16, 2013I'm extremely rusty at C but is this the best way to store an input string into a char*?
Code:
int length = 100; //initial size Code: char * name = malloc(length * sizeof(char)); //allocate mem for 100 chars
int count = 0; //to keep track of how many chars have been used
char c; // to store the current char
while((c = getchar()) != '
'){ //keep reading until a newline
if(count >= length)
name = realloc(name, (length += 10) * sizeof(char)); //add room for 10 more chars
name[count++] = c
}
Is this a good way and what could be better?
C++ :: Converting A String Input To Char?
Feb 8, 2015I am writing a program that asks the user for their gender. I know that atoi converts arrays into integers, but I need the input from the user in the form of F or M into a char, and return it to the main function to be displayed at the end of the program.
string Employee::getgender(char gen)
{
cout << "Please enter your Gender: " << endl;
//atoi function would go here, what for char?
getline(cin,gen)
return gen;
}

C++ :: Char Array To String - String Becomes Garbage
Apr 20, 2013I'm trying to "tokenize" a string using std::string functions, but I stored the text in a char array. When I try to convert it to a string, the string has the first character right but the rest is garbage.
// Get value from ListBox.
char selectedValue[256];
memset(selectedValue, NULL, 256);
SendMessage(GetDlgItem(hWnd, IDC_LB_CURRENTSCRIPT), LB_GETTEXT, selectedIndex, (LPARAM)selectedValue);
// Convert to string.
string val(selectedValue);

C/C++ :: Flip Char Array Input And Output It?
Nov 13, 2014So my question was:
Write a program to read in a sequence of characters one by one. Print out the characters in reverse. You should use a char[]. (Remember single quotes are used for char)
For example:
Please enter characters one by one: (Enter 0 to exit)
h
e
l
l
o
0
You entered: hello.
The reverse of that is olleh.
and this is currently my code
#include <iostream>
#include <cstdlib>
#include <cstdio>
#include <ctime>
#include <cmath>
using namespace std;
int main() {
char entry[20];
[code]....
im just not sure how to set that value and still make the for loops work
C++ :: Char Array Size - Undefined Until User Input
Apr 27, 2014So I'm trying to make a program, Which has nothing to do with the topic. But I ran into a problem.
I need to get a char array size of 6 doing:
char myChar[6];
but the size (6) is undefined until user input.
So I need to do char myChar[var]; (Var being 6 for now).
When I do:
char myChar[6];
It works!!!
But when I do:
int val = 6;
char myChar[val];
It doesn't work.
C++ :: Char Array To String
Oct 19, 2013I have some code:
char cHomeTeamFaceOffsPercentageWon[100];
memcpy(cHomeTeamFaceOffsPercentageWon,cSqlHomeTeamFaceOffsPercentageWon,100);
After this, for example, cHomeTeamFaceOffsPercentageWon is, "29%".
Then, I use
std::string szwPercentageWon = std::string(cHomeTeamFaceOffsPercentageWon);
szwPercentageWon is then, "2". Shouldn't this convert correctly, to "29%" as well.
Or is there something I'm missing? Maybe the termination character, or something.
C/C++ :: Taking String As Input And Making It As Whole Array (string Literal)

Mar 30, 2014In this program, I have to ask the user for an employee, then the program will check to see if the file for that employee exist, if it doesnt then it will automatically create the file.
ReadNew function reads the file....check to see if it exist
CreateNew function creates a new file.
In my code I have no problem with the first part of reading file.. and my createnew function works in other programs where I am asking for input of file name to create the file name. However in this code I cannot figure how to automatically pass the input filename from the ReadNew function to the CreateNew function. I can't ask the user to enter the name a second time, so I have to pass the input filename into both functions. Here is my code.
Code:
//Create a file, append to it, and read it.
#include <iostream>
#include <fstream>
#include <string.h>
#include <stdio.h>
using namespace std;
char filename[256];
string n;
string filelist;
void CreateNew(ofstream & FileNew);

Apr 3, 2013I have a text file with state names, and state abbreviations, thusly:

..and so on.
I have to load the abbreviations ONLY from the file into an array of char[ - (already done and tested).
I have to get a 2 char abbreviation as a string,then test it against the state array to make sure it is a valid abbreviation. As it stands, my test is never finding an invalid abbreviation..
Here is where I get the input:

C# :: Store Each Char Of A String Into Byte-array?
Apr 25, 2014I am trying to store each char of a string(string a ="1100") into a byteArray ( byte[] byteArray = new byte[4]. its not showing any error but its storing like below:
byteArray[0] = 49
byteArray[1] = 49
byteArray[2] = 48
byteArray[3] = 48
and what i want is
byteArray[0] = 1
byteArray[1] = 1
byteArray[2] = 0
byteArray[3] = 0
I don't know why but its replacing 1 with 49 and 0 with 48.what am I doing wrong or how to do this?
my code is as below
byte[] byteArray = new byte[4];)/>
int binArrayAdd = 0;
string a ="1100";
foreach (char Character in a)
{
byteArray [binArrayAdd] = Convert.ToByte(Character);
binArrayAdd++;

C/C++ :: Passing String Variable To Char Array?
Mar 30, 2014I have program where i have to check to see if file exist, if it does not then it needs to be created. SO I have a read file that works fine, if th efile exist it reads whats in it, if it does it says the file does not exist. Now Im trying to creata function that creates the file if it doesnt exist. so in my read function when the person enters the name of the file to be checked for..I pass that name to a variable called name..Hoping that I could then pass it into my create file function if it does not exist..and use that variable to pass the name they entered into the createfile array..called filename.. but I am having trouble because i get error when i try to pass from a string name to char array.. even when I change the varialbe name to char, or char [256] it will not work.. I try to fing a way to convert th string to a char using the strncopy function but still no dice..here the code i have for the createfile funciton
void CreateNew(ofstream & FileNew)//Create file
{
char filename[256];
string name;
[Code].....
How can i do this without having to ask the person to enter the file name twice..
