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 :: 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++ :: 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++ :: 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++ :: Bubble Sorting Vectors - Display Highest Temperature And Occurrence Time

Feb 12, 2013

I'm doing a project where I have to store information gathered (temperature and the time it was taken in seconds) in two separate vectors. After an unknown amount of data has been entered, and the end-of-file has been reached, I have to display the highest temperature and the time(s) it occured (bear in mind that the highest temperature may be recorded more than once). The output of that part should be as follows:

Highest temperature: 51
Recorded at time(s):
22:45
2:27

Something like that. The time should also be converted to hours and minutes. To the point: I've done some research on bubble sorting, but they only use it for arrays.

Visual C++ :: Retrieving Size Of Each String In Order To Produce A New Buffer For Concatenated String

Feb 25, 2013

What is the efficiency of the two assignments (line 1 and 2), i.e. (function calls, number of copies made, etc), also the Big O notation. I know there are function calls for retrieving the size of each string in order to produce a new buffer for the concatenated string...any difference between line 1 and 2 in terms of efficiency?

String s("Hello");
String t("There");
1. s = s + t;
2. s += t;

C :: Program Where User Inputs A String And Prints Out Length Of String

Jan 29, 2014

I would like to understand a function on strings. Below is a code that I took from my teacher where the user inputs a string and prints out the length of the string.

Code:
#include <stdio.h>
#include <string.h>
int main() {
char str[100];
int i = 0;

[Code] ....

Now I understand that it returns the count in "int" so my question is:

Let's say i declared

Code: int count = 0;
at the beginning of the code and then made
Code: count = strlen(str);
why wouldn't i have the same result? Is there a way to do it also?

C++ :: Eliminate Comma And Split String Into Individual String Variables

Nov 15, 2013

I have this string d ="3 J JD, K" and i want to split the string to individual string. I have this code which eliminates the comma but doesn't split the string into individual string.

#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main() {
string str = "3 J JD,K";
stringstream ss(str);

[Code] ....

Output of the code is
3 J JD
k

but I want
3
J
JD
K

Also after I split the string is there any way to put the split string into individual string variables.

C/C++ :: Comparing Input String To Type String Vector

May 29, 2014

I wrote a program that reads a list from a file and stores it in a string type vector. Now, I want the user to input a word so that the program can search the vector to see if that word already exists. I have used every possible way of reading input from the console and storing it in order to compare with the vector but it never results in a match. When I print the input string and the vector string they are exactly the same thing (or at least print to the console as if they were). I've tried using getline; using cin direct to a string var; using cin to a char array and then casting to string using string str(arr); I even added a newline at the end just in case and STILL I cannot get a match.

vector <string> currentSet; //read a list in from a file and has 9 items in it
cin.ignore();
string line;
getline(cin, line);
if(line == vector[0]){//if printed to console line is HEAT and vector[0] is HEAT
cout<<"match"<<endl;
}
