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++ :: 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++ :: Program That Counts Number Of Occurrence Of A Letter In A File

Feb 3, 2013

I need to create a program that asks the user for the filename, then counts the number of occurrence of each letter in that file.

Ex. if the file contains
Absacsac
asdasda

Output will be

a = 6
b = 1
c = 2
.

.
z = 0

This has been my program so far:

#include <iostream>

C++ :: Crypt Arithmetic Puzzle - Replace Each Letter As S Number

Oct 28, 2013

Dont know how to replace each letter as s number ... this is the question i was given ...

In cryptarithmetic puzzles, mathematical equations are written using letters. Each letter can be a digit from 0 to 9, but no two letters can be the same. Here is a sample problem:

SEND + MORE = MONEY

A solution to the puzzle is S = 9, R = 8, O = 0, M = 1, Y = 2, E = 5, N = 6, D = 7.

Write a program that finds a solution to the cryptarithmetic puzzle of the following:

TOO + TOO + TOO + TOO = GOOD

The simplest technique is to use a nested loop for each unique letter (in this case T, O, G, D). The loops would systematically assign the digits from 0 to 9 to each letter. For example, it might first try T=0,O=0,G=0,D=0, thenT=0,O=0, G = 0, D = 1, then T = 0, O = 0, G = 0, D = 2, etc., up to T = 9, O = 9, G = 9, D = 9. In the loop body, test that each variable is unique and that the equation is satisfied. Output the values for the letters that satisfy the equation.

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 :: Program That Will Repeat K Times Each Single Occurrence Of A Vowel?

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.

Code:

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

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.

C :: Replace Tabs With Spaces

Jul 14, 2013

Basically, the task is to replace tabs with spaces, ensuring that the number of spaces is appropriate to get you to the next tab stop (i.e. if you were only 4 spaces away from a tab stop, don't replace the tab with 8 spaces).i've seen have included character arrays, and many have included multiple functions. I realize the text says "these exercises suggest programs of somewhat greater complexity than the ones earlie in this chapter," but it seemed like a very straightfortward task.Have i oversimplified or something?

Code:

#include <stdio.h>
#define TAB_STOP 8
int main()
{
int c, i;
}
