I would like to insert some character after each number of my string .. I found how to insert before each character, but what I want is :
string str = "12 + 5"
insert ^ after each number
Output = "12^ + 5^"
Let's say i have a string "file.txt" and i want to insert "_out" to make it look like "file_out.txt"
I don't know how to do this ....
I'm trying to determine the number of times I have to change each specific character in a string to make it a palindrome. You can only change a character one at a time from the end.
Example: "abc" -> "abb" -> "aba" should print 2. "aba" will print 0 because it's already a palindrome. "abcd" -> "abcc" -> "abcb" -> "abca" -> "abba" will print 4 because it took 4 changes to make a palindrome.
I'm not too sure how to approach this - I figured out the case where if it's a palindrome (if reversed string is the same) then it'll print out a 0.
int main() {
int number;
cin >> number; //expecting a number for first line user input
for (int i = 0; i < number; i++) {
string str;

I'm new to strings. I want to know how to insert a string right in the middle of another string.Is it possible to do that? for example my first random word is 12345678 and the 2nd random word is jimmy I would have to write .
This in my code uno.insert(4,dos); for jimmy to be printed in the middle of the first string,but what if my 1st random word is has more than 8 characters what would I do in that case?
Code:
cout << "type random word" << endl;
getline (cin , uno);
//greatavenue
cout <<"enter random word#2"<<endl;
getline (cin , dos);
//_coconut_
uno.insert(5,dos);
cout<<uno<<endl;
//great_coconut_avenue
So I'm trying to create a function that replaces any instance of a character in a string with another. So first I tried the replace() string member function:
In my implementation file
void NewString::ReplaceChar(const char& target,const char& entry)
{
this->replace(this->begin(),this->end(), target, entry);
};
Main program
#include "NewString.h"
using namespace ...;
int main()
[Code].....
Instead of replacing the the l's with y's it outputted a long string of y's. Also, NewString is derived from the string class (it's for the assignment). the header and whole implementation file, already tested.
I've also tried, instead, to use a for loop in ReplaceChar() but I need to overload the == operator and I don't know how I should exactly:
bool NewString::operator ==(const char& target)const {
if(*this == target)
return true;
[Code]....
I want the == operator to test if the value in the char array is equal to target but I'm not sure how to pass in the position. I'm guessing the this pointer in ReplaceChar() is not the same as the one dereferenced in ==() because target is never replaced by entry in the string.
I think std::copy appears to do what I'm looking for.
I'm in need of a vector member function that would allow me to "insert" a number of elements from one vector into another vector without resizing or destroying either.
An example of what I'm wanting to do is assign the contents of two[3-5][50-54] to one[7-9][2-6]. Other than looping through both vectors using .at(), is there a way to copy this?
This would be continuous within a user controlled loop with differing elements being exchanged.
typedef vector<vector<unsigned char> > vec;
vec one(10, vector<unsigned char>(10, '1')),
two(90, vector<unsigned char>(90, '2'));
I'm trying to make a function that lets me pass an index and a string and will insert the string at that index in the linkedlist... here is so function i have so far:
Code:
typedef struct node {
char* value;
struct node* next;
} LinkedList;
void llAddAtIndex(LinkedList** ll, char* value, int index) {

how to insert a variable for the size of array and prompt user to insert the elements for the array?
View 13 Replies View RelatedAny way to do it...its only works with the first letter. So i have a txt file with information such as de3 dn5 dn7 dw9 ds1 and how to get the letters and then the number.
example:
if de print this is de; and print the number that follow de
Code:
#include <stdlib.h>
int main ()
{
FILE * pFile;
int c;
pFile=fopen ("de3.txt","r");
if (pFile==NULL) perror ("Error opening file");

I created a function to check whether the first character of a string is a number or not by comparing it to every base 10 digit using a for loop. If it is, the string is valid, if it is not, the string is not valid
Code:
//ensure the first character is not a number
int ValidFirstChar(char FirstChar) {
int IsChar = TRUE, DigitCount = 0; /*boolean value indicating whether the first character is a number or not.*/
//check through all base 10 digits
for (DigitCount = 0; DigitCount <= 9; DigitCount++) {
if ((int)FirstChar == DigitCount)
[Code] ....
I have checked for the case where the first character is a number but it is displaying the error message for it. I have tried typecasting the char variable but that has not worked.
how can i display the number of variables or character that the user input?
View 4 Replies View RelatedI'm trying to get the int value of each character in a string and then add them all together so I can do a 1's complement of the total value. I'm trying to do simple checkum kinda of thing for verification of data.
For example: string DPacket = "Hello World!";
I would like to have each character added and do the ones complement. Will it be easier to convert first to int and then add or any other easier way? So my result should be the decimal value addition of each character and then do the ones complement to that.
Im programming a roguelike game using visual c++ Microsoft express 2010 and i made a multidimensional array for my first map. I have the walls as # and was wondering how i could turn those into ascii symbol 219. Also i need to know how to turn specific text certain colors.
View 5 Replies View RelatedI know how to remove certain characters from a string by using something like this:
Code: string str ("Hello world!");
erase (0, 6);
That's great if I want to do that manually, but say if someone entered a string, how would I automatically remove every other character they entered?

Copy some characters from char * arg to char * first using a loop with specific conditions.
Code:
char * arg;
// set arg some string...
char first_[25];
char * first;
int length;
length=strlen(arg);
for (n++; arg[n] != '}' || n>=length-1; n++)
strcpy(first,arg[n]); // first += arg[n]; I have strcpy(first,arg[n]); but arg[n] is char and strcpy expects char * ;
how to solve this?
It's been about two years since I last program c, now I need to do it for a basic project. How would I print out one letter in a string?
For example lets say I have a string called str=[Hello]. I want to display the third letter so just the "l". Here's what I have so far:
Code:
#include<stdio.h>
int main() {
char str[50] = "Hello";
printf("The third letter is : %s
",str[3]);
return 0;
}
I'm trying to find a < character in a document, get it's position. Then find > and get it's position. Then i want to delete all things between that but runtime is terminating my process so i don't know what to do.
The code:
#include <iostream>
#include <conio.h>
#include <stdio.h>

I want to input a string, say: abcdaa so, the program should output:
a
b
c
d
In other words, the program will display each character for only ONCE!!!! And display their frequency. Here is my idea: user will input a string and such string will be copied into another string variable called "checker".There will be a loop and each character will be printed, BUT, first, the program will check if the character to be printed is not equals to all elements of the checker string.
I already have the function to count the frequency of each character
GOAL: to make a program that will accept a string and use the HUFFMAN CODING to compress it.
for(x=0; x<string_in.size(); x++) {
cout<<" "<<string_in[x]<<endl;
for(y=0; y<string_in.size(); y++) {
if(checker[y]==string_in[x])
break;
else
checker[x]=string_in[x];
}
}
I have an open file dialog that opend the xml file and store the path to the textbox, it returns the path correctly but when i need to store that xml file into the database it tells me that there is an error next to '' because when i try to debug it it gives me "C:\Student Results\FC2015.xml" this results then it breaks. here is my code:
This code returns xml path to textbox
OpenFileDialog ofd = new OpenFileDialog();
ofd.Filter = "XML Files (*.xml)|*.xml";
ofd.FilterIndex = 0;

I need to make a function that removes a function in a c-string. This is what I have:
#include <iostream>
using namespace std;
char removeCharacter (char *str, char c)
{
[Code].....
I keep getting this error after I input:
Code:
Unhandled exception at 0x54AE350B (msvcp110d.dll) in Random.exe: 0xC0000005: Access violation writing location 0x0131CA21.
Code:
#include <iostream>
#include <cstring>
//Prototypes
void lastChar(char *);
int main() {
const int LENGTH = 21;
[Code] ....
It builds without any errors. I am just trying to output the last character in the C-string. Am I doing this all wrong?
Everytime I type a character, the number 1 appears in the next line. And i just keep getting the message "Wrong! I have more than that." even when I type a number bigger than 1023
Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main(void) {
srand(time(NULL));
[Code] ....
The function uses a "for" loop to print the given character the number of times specified by the integer.
How can I make a for loop to do that?
So.. my code looks like this:
// cpp : Defines the entry point for the console application
//
#include "stdafx.h"
#include <iostream>
using namespace std;
void printMyInteger(int myInteger, char myChar) {
[Code] ....
So.. here is my error:

I wish to convert a character directly to a string for a top-secret project I'm working on. It needs to be portable across various machines with different sized Indians.
Code:
#include <stdio.h>
int main(void)
{
const int i = 0x0041;
const char *str_p = (char *) &i;
}
[code]....
I want this to output an 'A', but I'm not sure this code will work on my friend's mom's S/360.
I am still working on my project which will be reading some old data from some old DOS files. The data stored there is naturally, char*. Once I read in my character array, how do I assign this to a wstring since my application is UNICODE?
Here is my current solution:
wchar_t* Class::Function(char *pName) {
//I verify the pointer and such first, then do the below
this->_Name.assign(pName, (pName + strlen(pName));
return this->_Name.c_str();
}
Am I on the right track here?
