C++ :: Counting Occurrence Of Char In Array

Aug 25, 2013

I have

#define LessSymbol -1
#define MoreSymbol 1
#define NeitherSymbol 0
#define MAX_COLS 20
#define MAX_ROWS 20
#define MAX_CHAR 3

char averageMap[MAX_ROWS][MAX_COLS];
char rowCount[MAX_ROWS][MAX_CHAR];
char colCount[MAX_COLS][MAX_CHAR];

I have other stuff in the code, but basicly, at this stage i have a map of 1's,-1's and 0's in a 20 x 20 map. I just want to count the occurrences of each and basicly tally them in the 3 colums/rows at the end of the bloc. so far ive tried many different if statements, here is what i tried last.

for(row = 0; row < MAX_ROWS; row++){
rowCount[row][0]=0;
rowCount[row][1]=0;
rowCount[row][2]=0;
} for(col = 0; col < MAX_COLS; col++){

[Code] ....

Its outputting 20 as a result for each row. Its like its counting the symbol no matter what it is.

C/C++ :: Counting Letters In Char Array

Dec 7, 2014

Assume input is char array holding a C-string. Write code that counts the number of elements in the array that contain an alphabetic character.

counter = 0
for (i = 0; i < SIZE; i++) //size being whatever input's size is
{
if (isalpha(input[i]))
{
counter++;
}
}

Is there anything wrong with this method?

C :: Selecting The Highest Occurrence Char

Dec 14, 2014

it's not my primary language, so my code variables are in my language.

Code:

FILE *eng;
eng = fopen("eng.txt", "r");
if(eng == NULL){

[Code]....

fclose(eng); It's a piece of my code. Some explanation: From file, where is full of words under selves. I cut it on word and from word i'm printing:

1) word
2) how many letters in the word
3) word backwards and
4) viz. problem is down

For first: There i have warning: while(feof(eng) == NULL); like (comparison between pointer and integer) i don't get it. For second i have a big problem. I must from every word print the most recurring character.

For example: nondeterministically -> the most are N and I. And if, there is more then one most reccuring char, you choose one of them.

C/C++ :: Read Integers Into Array / Sort Numbers And Print Out Occurrence Of Each Number

Apr 6, 2014

My C programming class wants us to write a program to read integers into an array, sort the numbers and print out the occurrence of each number. I've tried everything that I can think of but the core dump is still occurring.

void countValues ( FILE *inf, int list[], int size ); /* Function prototypes. */
void printFrequencies( const int list[], int size );
int main (void) {
int status = EXIT_SUCCESS; /* defaulting status to success. */
FILE *inf = fopen( "numbers.txt", "r" ); /* input data file */

C++ :: Counting Integers With Array?

Mar 21, 2014

I now know how to count integers with while loop but I'm not sure how to count the integers with array.

So the question is:

1. program should keep reading integers as long as the integers are within [0,9999]
2. when user typed the integer not between 0 to 9999, the program print out the numbers of integers that were typed.

Sample
3
3
3
9999
9999
-1
You entered 3 3 times.
You entered 9999 2 times.

#include <iostream>
using namespace std;
int main() {
int i=-1;
int x;
int numbers[10000];

[Code] ....

I cannot use "do" ....

C++ :: Comparing Char Array To Char Always Returns True

Dec 23, 2014

I've made a code to check whether or not a save file has been created correctly, but for some reason it always returns this line: readdata[qa]=='1' as true. in which qa is the counter I use in a for loop and readdata is a character array consisting of 50 characters that are either 0, 1 or 2.

this is the entire code:

#include <iostream>
#include <fstream>
#include <string>
using namespace std;

[Code]....

at first is also went wrong at line 22 and also returned that as true, but then I added brackets and it worked.

C++ :: Concatenate Two Char Arrays Into Single Char Array?

Sep 29, 2014

I am trying to concatenate two words from a file together. ex: "joe" "bob" into "joe bob". I have provided my function(s) below. I am somehow obtaining the terminal readout below. I have initialized my memory (I have to use dynamic, dont suggest fixing that). I have set up my char arrays (I HAVE TO USE CHAR ARRAYS (c-style string) DONT SUGGEST STRINGS) I know this is a weird way to do this, but it is academic. I am currently stuck. My file will read in to my tempfName and templName and will concatenate correctly into my tempName, but I am unable to correctly get into my (*playerPtr).name.

/* this is my terminal readout
joe bob
<- nothing is put into (*playerPtr).name, why not?
joe bob joe bob
seg fault*/
/****************************************************************/
//This is here to show my struct/playerInit

[Code]....

C++ :: Counting Elements Of Constant Array?

Aug 21, 2014

This is going to seem like a stupid question but how can I count the elements of a const array. Surely c++ compilers provide a count for const arrays?

const wchar_t* ItemHandler::itemNames[] = {L"Coins", L"Matches"};
const wchar_t* ItemHandler::itemIconLocations[] = {L"./media/Items/coins.png" , L"./media/Items/matches.png"};
const bool ItemHandler::itemStackable[] = {1, 1};

I want to count the elements so if the server sends a bad item id it won't crash every client in range lol. I heard that the sizeof keyword returns the size of the array in bytes. I used to think the size of keyword would return the element count but found out it isn't.

C++ :: Replace 2nd Occurrence Of Letter?

Apr 27, 2013

i`m currently racking my brains out over this issue. How do i go about the x as the first occurrence of the letter?

lets say helxo , x is the 2nd occurrence of l. I will want to change back x into l

i have replaced it with x in the earlier step with this code...

string everySecondChar(const string &s,char source,char distance)
{
string t(s);
for(std::string::size_type even =0,pos=t.find(source,0);pos!=std::string::npos;pos=t.find(source,++pos))
{

[Code]....

i would like to reverse the process now, letting x becoming l again!

C++ :: How To Replace 2nd Occurrence Of A Letter With X

Apr 21, 2013

Supposed i have a word hammer.

how am i suppose to search for the 2nd occurrence of the letter and then replace it with x?

example hammer will become hamxer

I thought about using replace for it, however i`m lost on how to find 2 occurrences of the same letter in the word.

string formatEncrypt(string message) {
int msgLength=message.length();
for(int i=0;i<msgLength;i++) {
if(message[i] == 'j' {
message[i]='i';

[Code] .....

at line 31 i tried to put a z into the alphabet that occurs twice.

this is what i have done so far

example: hello world

It will turn out as helzlo world

However i want to make the output appear as helzo world

C :: Parsing Char Array To Array Of Struct To Process Packets

May 28, 2013

I wrote this simplified version of a program i am writing that parses data in UDP packets. In the process of doing so i pretty much answered all my questions and fix all the problems i was having.

decodeSystemMap function will be in loop, and will proccess packets that have mostly the same data, only a few items will be added or changed or deleted.

whats the best way to check if there are any new, deleted, or removed items in the packet and only modify those?
Is there anything unsafe / dangrous about the way the code is now?

Code:
/* * File: main.c
* Author: david

* Created on May 23, 2013, 11:57 AM
*/

#include <stdio.h>
#include <stdlib.h>

Jun 8, 2014

Repeat the vowel Problem 3 (0 / 0)Write a program that will repeat k times each single occurrence of a vowel in the input file "sp.txt" to a new file "output.txt". The first line of the input file contains only the parameter k. The first line (containing the parameter k) should not to be written in the output file.

I wrote the code but i cant figure out something. i read the file, i found the vowels but then i cant print them.
