I am trying to print out the letter frequency of a vector that the user inputs and what number that letter is in the ASCII. I am supposed to say, for example: "w" which is ASCII 119 occurs 2 times. How to do this?
View 1 RepliesI am new to c++. I am writing a program that reads in a text file and gives a count of how many times each letter appeared in the file. I got it to read the text file and do the letter count. B
X = 102
Y = 126
Z = 165
etc...
THAT IS WORNG
The sample output should be
E = 165
T = 126
A = 102
O = 93
etc...
I got it to sort from lowest to highest for the frequency, but cant seem to get the appropriate letter assigned to it.

I am working on my second c++ project that is a statistical analysis of a vector data set of integers. I created a struct called range with a maximum value, minimum value and count for occurrence. The frequencies are stored in a vector<range>.
I have tried messing around with the increment to get the high range test above the maximum element, though my ranges cumulatively increase by 9.9. I'm not sure how the professor's program has the distance between high and low ranges as 10 instead of 9.9, which is the increment. I'm also unsure why half way through his buckets, the ranges appear as 9.99 briefly and then return to 10 after (40.00 - 49.99 then 49.99 - 59.99). I feel like I am missing something very obvious on line 04 or 10 in my code.
Here is the code for the frequency that accepts a vector reference for my data set of integers.
void frequency(vector<int>& data_set){
double max = findMax(data_set);
double min = findMin(data_set);
double increment = (max - min) / 10;
double percentage = 0.0;

I have taken a keen interest in writing trading programs. I have some Python background, a little C# but no C++.
The example below was provided in a book on HFT and I would love to see how the results look. I was hoping that I would just compile it and away you go!
That didn't happen. To start with the author listed this as a function, so I converted it to a main program. Still having issues with my path and where to see the output. Here it is..
Code
void HFT_AvellanedaStoikov() {
FILE* fin, *fout;
double lambda_a, lambda_b, d_lambda_a, d_lambda_b;
int hh = 0, mm = 0, ss, nb = 0, na = 0, prevnb = 0, prevna = 0, prevm = 0;
double bid, ask, prevbid = 0, prevask = 0;
char * p1, *p2, buffer[1024], fname[512];

The code shows all characters frequency, however i want to find which one has highest frequency
For example cprogrammmmming cboard
highest frequency: m

printf("Enter a string
");
gets(string);

I'm trying to figure out the word frequency of a user inserted string. I've tried doing it via getline of the struct array and via the getline of the string word but neither either the former crashes or the latter just prints out the whole string.
Here is the latter.

#include <iostream>
#include <string>

How to handle the array of structs.
I have been working on a project that deals with an array of characters and finding there frequencies. I was able to determine the frequencies that where greater than 1, but I need to find the HIGHEST frequency.
Here is my full code:
#include <iostream>
using namespace std;
void input(char unlisted[80], int& n);
void bubblesort(char unlisted[80], char sortedlist[80], int n);
[Code].....
As you can see this will print out all frequencies that are bigger than 1, but I only want the highest frequency. Basically I want to print out all frequencies when count is greater than 1 less than count, but because its in a loop count will always be greater than count-1 so it prints out all frequencies.
I designed one mfc vc++application in which data received from udp is stored in file as well as in stack.I used stl for stack; it stored elements as per receiving order,but i want to return repetitive number from stack,how to use stack as function parameter & retrieve elements of stack as an array? I write code for push elements in stack given below.
<template< typename T > void pushElements( T &stackRef,int value) {
stackRef.push( value);
}/>
the code shows all characters frequency, however i want to find which one has highest frequency for example cprogrammmmming cboard highest frequency: m
char string[100], ch;int c =0, count[26]={0};
printf("Enter a string");

We have to make a code to detect the frequency of printable characters. But when I run the code, sometimes it can't detect the Uppercase Letters. But it can sometimes. It's a bit buggy, and it really can't get the frequency of the space character.
Does textcolor affect the outcome?
Code:
#include<stdio.h>#include<conio.h>
int main ()
{
clrscr();
char name[40],sentence[1000],ch;
int c=0,count[95]={0};
textcolor(LIGHTCYAN);
[Code] ....
I also noticed that it stops detecting the frequency when there is a space between character/s.
c++ program which reads an input stream from the keyboard that counts the frequency of occurrence of all the letters of the alphabet

Create a program that finds all numbers in an array that show up exactly 5 times. I am trying to solve this issue by making a frequency distribution via two loops and two arrays, but I am having trouble getting my loop to not recount a number it has already counted.
For example, if you enter ten 1's into the "entered Numbers" array I want it to store a count of 10 in frequencyarray[1]. Instead it is storing
frequencyarray[0]10
frequencyarray[1]9
frequencyarray[2]8
etc...

using namespace std;
void enternumber(long[], int);
int main() {
int size;

I'm new in programming, and trying to write a code in C. The requirement is following - to write a text, and to find frequency of 1 chosen character in it. The main thing is that program should check user input (for example, I want to check if user entered "char" --> then correct, or if entered "int" --> not correct). But the program still doesn't check. So I have:
Code:
#include <stdio.h>
int main(){
char c[1000], ch;
char i, count=0;
printf("Enter a text: ");
gets(c);

Can I capitalize first letter of each word without using arrays ? If yes, how can I ?
View 11 Replies View Relatedi`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))
{

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

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

How would I detect if any letter key is pressed. Would I have to use GetAsyncKeyState() for every letter key? Or could I have some kind of loop going through all the hexadecimal values for every letter? I don't know how I would go through hexadecimal values with a loop.
View 6 Replies View RelatedI need to count how many times letter appears in a text. I know that for default letters from 'a' to 'z' and from 'A' to 'Z' there is an interval. But I need also Lithuanian letters, such as ž,č,ę. I wrote this method: (it accepts char code and checks whether that char is a letter)

As you can see, a lot of checking in switch statement. I use 256 for this reason to have the same effect as unsigned char. But maybe there is a way to shrink down this method, or use some library?
I just would like to turn this into cpp:
string eg("azertyFTW");
if(eg[one of the letters contained in this string] == 'c') {
cout << "eg has the letter c in it";
} else {
cout << "not this time :(";
}
I wanna know why the program doesnt show "Invalid Letter Entered" when i enter any letter other than A S D or M
//Processing the data
if (letter== 'A'||'S'||'M'||'D')// checking Add, subtract, multiply or divide {
if (letter== 'A')//Adding the integers
cout<<"Adding two integers = "<<first + second<<endl;
else if (letter== 'S')//Subtracting the integers {

I am doing a homework assignment. I do not want the complete answer, just a hint. I have to load a file of names into an array, display the names, then sort the names alphabetically, display them again, then list how many names start with certain letters. I have everything done but how to display how many names start with a certain letter.
Here are the names:

Allen, Jim
Griffin, Jim
Stamey, Marty
Rose, Geri

I'm supposed to count the number of first capital letters in a string. I've written a code that counts every uppercase letter, and it turns out that this is not what the assignment is about. For example, the input "JAMES, How Are you?" should return an output of 3 (mine would return 7 in this case). Only J, H, A need to be counted.
Code:
#include <stdio.h>
#include <string.h>
#define MAX 100

FILE *f = fopen("text.txt", "w");
char c;

How do I fix this?
In C how can I initialize a variable that is not a letter or number? For example with a number I can :
Code:
int i = 5;
for ( i = 0; i <=5; i++ );
printf( "%d", i ) This would display a row of 5's
but what if I wanted to display a row of -----? What I am trying to do is read in a simple txt file, around the file I want ----1----2-----3 ect ect on the top ----a----b-----c down the side Then I want to be able to change the file at lets say position c2 and save it. This is the early stages of my attempt to set up a editable table.
