C/C++ :: Find The Common Characters Between Two String Characters
Jul 6, 2014Im supposed to find the common characters between two string characters, assuming that the user wont input duplicate letters like ddog. When I run my code I get an output of a question mark upside down. Here is my code with comments on what each part is supposed to do
#include <stdio.h>
#include <stdlib.h>

C :: Comparing Of Characters In Given String From Input String?
Feb 7, 2013I am stuck in this program, Be given a string of chars, where each single char belongs to the following alphabet: a..zA..Z0..9 (So, in the string there are only lowercases, uppercases and digits. No blank, no comma, ...). For every char of the given alphabet, count how many times in the string
1-- the char belong to a sequence of identical chars whose length is at least three (i.e.: in the string cc74uyrpfccc348fhsjcccc3848djccccc484jd for three times the character 'c' satisfies this condition)
Code:
#include<stdio.h>
#include<conio.h>
#include<string.h>

2-what is the longest substring of characters strictly rising interm of ASCII code(the following is greater (>) of the previous)
3- what is the longest substring of successive characters interm of given string rannge (i.e.: fhkjshdfruytyzABCDEfglsj => 7)
C++ :: Delete Words From A String?
Feb 3, 2015"Type a function that take in a string containing numbers and others characters and print on stdout all the numbers contained into the string, where for number is mean every maximal numerical sequence, of numbers not separed by spaces. Numbers printed on exit must be separated by commas. For example, if i put in the function the string "paje27hg78 2k f562" my function must print:
27, 78, 2, 562 "
So i started my code like so: (I WANT TO NOTICE THAT WE HAVE ONLY USED IOSTREAM AND FSTREAM LIBRARY FOR NOW, SO DON'T USE OTHERS LIBRARY ELSE MY TEACHER WON'T CORRECT MY HOMEWORK!)

C :: How To Delete All Occurrences Of A Char In A String
May 17, 2014I want do delete all occurrences of a char in a given string, but I really don't see my error in the code. Here is how I did it:
Code:
char *input = "example_string";
int len = strlen(input);
char *new_line[len];
char bad = 'e'; //the one to delete
int i;
int j = 0;

I get segmentation or bus errors.. And I also don#t understand the warning I get. new_line is an array of chars, and I am trying to assign to it a certain char.

View 3 Replies View RelatedC++ :: Removing Characters From A String
Nov 1, 2013I want to remove a particular character from a string. Say '.'. I've tried the following:
void removeDots(std::string &x)
{
std::remove_if(x.begin(),x.end(),[](char c){return (c == '.');});
}
This has the effect of removing the dots but keeping the length of the string the same, so old characters are left over at the end. Is there an extra action to do to x to make it the right size or is there a better way of doing it?

C/C++ :: How To Uppercase All Characters Of A String

C/C++ :: How To Cout The String Characters Themselves
May 11, 2014Iam working with arrays and i cant get to the write solution to cout the characters.
the Question is : Write a program that inputs a character string from the user as an input (using cin.get())and store it in myStr[ ] array.Assume that the length of the input string is less than 100 characters and the string may contain lower case, upper case, and/or symbols.The program should then print the number of lower case, upper case, digits, and symbols along with the characters themselves.
my code :
#include <iostream>
#include <string>
#include<iomanip>
using namespace std;
int main() {
int ctr1=0, ctr2=0, i=0, ctr3=0;
[Code] ...
What i have now, how can i cout the uppercase characters and the lower case characters and the symbol characters !
C/C++ :: How To Ignore Certain Characters In A String
Sep 18, 2014I am trying to cout just the first 5 characters the user enters into a string. I'm not sure how I can discard or not show the rest of the characters they try to enter after 5.
#include <iostream>

C :: Entering Characters Into A String Pointer
Feb 8, 20131. The debugger shows that the characters are entered into the word pointer, and when a punctuation or space character is encountered, I terminate the string with a ''. But when I use puts to print the string, garbage is printed. Why is this?
2. Also, if I don't allocate memory for word the compiler gives a warning about it being used uninitialised. But I didn't allocate memory for the array of pointers(words), and the compiler didn't give any warnings. Whats the difference between a pointer and an array of pointers?
Code:
// wordcount.c - count words.

#include <ctype.h>

C :: Copying Characters From One String To Another With Pointers?
Apr 14, 2013So I'm writing a function isPalindrome() that can accept a string as an argument, and copy from it only the alphabetic characters in the argument (original) string to another string named alpha_array which contains only the alphabetic characters. Then the function should be able to call the isPurePalindrome function to determine if alpha_array is an ordinary palindrome.
The problem is that when I call isPalindrome in main, the program crashes.
Here's the code I have for isPurePalindrome and isPalindrome:
Code:
/* 1 */
int isPurePalindrome( const char * sentence ) // Can accept strings, array and pointer arguments
{
// Declarations

View 6 Replies View RelatedC :: Print String With Escape Characters
Mar 7, 2013is there any function to print a string with all the escape characters in it?
For example, instead of printing:
This is a string.
It would print:
This is a string.
Or in Windows:
This is a string.
I know that you can debug the code to find the variable contents, but is there any way to accomplish this with some standard library function?

This program is suppose to read a matrix file , and the first getline is suppose to get the file header but it appears that 'line' doesn't take in any value other than empty thus causing all the problem , I tried to put cin.getline() in front of it to take away the /n created by the cin before it , but it doesn't work . When I debug the program when the arrow points to the string line , this error appears
line<Error reading characters of string.>std::basic_string<char,std::char_traits<char>,std::allocator<char> >
I tried to initialize string line=NULL too , doesn't work either.

C++ :: Finding If String Has Unique Characters
Mar 28, 2013bool isUnique(string _str)

bool char_set[256];
int len = _str.length();
memset(char_set, '/0', 256);
for(int i = 0; i < len; ++i)
[Code] .....
I came across this code to find if string has unique characters...i didnt understand why they subracted ascii value of character '0' in the statement int val = _str[i]- '0' and what is happening with the statements...
if(char_set[val])
{
return false;
}
char_set[val] = true;
I take each character in the sting and traverse the whole string .and if count is 2 i use break and conclude that its not unique and not otherwise...can i use this method or this is not efficient????
C/C++ :: Counting Characters In A String / File
Jan 19, 2015I have the following program
#include "stdafx.h"
#include "string.h"
#include "ctype.h"
/*selection sort*/
void swap(int A[], int j, int k) {
int p = A[k];
[Code] ....
Theoretically it should cound the number of apperances of each character in a string, but:
1) It is counting characters from letter "j" upwards thus all asci characters below "j" are not counted, why is that?
2) I want also to make this code calculate the number of apperances of each character in a txt file. How to do that, i know i have to open a file in read mode, that's all (I am new to c programming)?
C++ :: Decoding Unicode Characters To String
Jan 6, 2013I'm having some problems in receiving fileNames from Server to Client(C++) in Mac OS X. I send a serialized object , which has a char pointer with the fileName or sometimes a string object, when i receive it in the client, it seems to be having %F6 or %E9 ,etc . This issue don't arise in Windows OS though, even thought it's the same code. Is there anyway decoding these '%' characters back to their original form in Mac OS & Linux ..?
Fex characters i got into problems with : ǡ ȅ ȉ
It would be difficult to change the code in server, so if there's a way decoding the characters back to its original form, it would be easier.I'm using Boost Library for Serialization and i'm just looking for ways to decode %F6 back to ȅ in C++, like if some library is available ..?
