C/C++ :: Finding Highest Frequency From Array Of Characters
Jan 27, 2015
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.

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");
gets(string);
[Code].....

after staring at this for awhile, I can't figure out why it won't work. It prints out numbers from 0 to 100, but will print out an absurdly high number as the highest number, like 790 or 640. I can't see why.
Code:
#include <cstdlib>
#include <ctime>
#include <iostream>
using namespace std;
int find_highest(int array[]);
int find_highest (int array[], int size) {
int highest_num;
for (int i = 1; i < size; ++i) {
if (array[i] > array[i-1]) {

I keep getting an unresolved external symbol error in the double GetHighest function. Ive looked over the code many times and can figure out why its giving me this error.
//Question 1
// Copy source code below and save to a .cpp file (say lab11_01.cpp) and write statements to print what is indicated in the source code.
//In this question, you will implement code for finding the highest value in an array, and you do this in a function.
//This program gets a series of test scores and calculates and display the highest score.
#include <iostream>
#include <iostream>
#include <iomanip>
using namespace std;
// Function prototypes
void getTestScores(double[], int);
double getHighest(const double[], int);

I have this multi-dimensional array. There are 12 rows, each represents the months, and 2 columns, the 1st column represents the lowest temperature and the 2nd column represents the highest temperature.
I need to find the lowest temperature in only the first column and the highest in only the 2nd column.
This takes in the temperatures. LOHI = 2, MONTHS = 12, LOW = 0, HIGH = 1
void PopulateTemp(int temp[][LOHI])
{
for(int month = 0; month < MONTHS; month++)
{
cout << "Month " << month+1 << endl;
[Code]......
My professor said we only needed 1 for loop as you only need to read the data from one column in each?

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.

We're writing a program in class using data structures and arrays and I'm stuck on writing a loop to find the students' highest test score. I only return the first student's ID, test score, and grade. For some reason unknown to me I'm not actually looping through all 12 or so records.
Code:
#include <stdio.h>
#define MAX_ENTRIES 50
struct records
{ //declare my student records structure
int ID; //the student's ID number
int test_score; //the student's test score
char grade; //the student's letter grade of aforementioned test score
};

I've recently been reading tutorials on arrays and their aquaintance with memory addresses. So, I completely understand how an array's name, when defined, is a constant pointer to its first element's address.
My problem, however, lies with characters, and how they are basically arrays except with a null terminator for the last index. What I've come to undestand, is that, when defining a character variable, each 'character' has a memory address it is associated with.
For example:
char name[] = {"Hello"}; // | 'H' | 'e' | 'l' | 'l' | 'o' | '/0' |
An address holds the value of 'H'.
An address holds the value of 'e'.
An address holds the value of 'l' and so on.
I have come to believe this is false, however. Mainly from a simple std::cout command.
std::cout << &name << std::endl; // attempt 1
std::cout << &name[0] << std::endl; // attempt 2
The first attempt, as I assumed, should print the address of the first element.
The second attempt, as I assumed, did not. I figured, &names[0] would print the address of the first element, which should have been the same as &names.
So, this brings me to my question, are characters formed of constant addresses, or are the address of individual characters not reachable?

I am looking for a way to correctly count the lines between two specified characters/strings in a file. Here's the part I need work on:
getline( file, lines );
do {
if(lines.find("character")
{
++counter;
}
} while( !lines.find("story") );
I want the code to search for the first occurence of the word "character," and start counting the lines from that line until it hit the first occurrence of the word "story."
Right now, I am only getting a counter value of 1.

bool 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????

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 "stdafx.h"
#include <iostream>
#include <string>
#define MAX_WORDS 200
using namespace std;

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...
#include <iostream>
using namespace std;
void enternumber(long[], int);
int main() {
int size;
int numbers5=0;

so my question is i want to print characters,no string just an array of characters,i do this but it s not working,maybe i have to put the '' at the end?
Code:
int main() {
int i;
char ch[5];
for(i = 0; i < 5; i++) {
scanf("%c",&ch[i]);

I have an array of characters. I am trying to find "houston". The only way I can think of to do this is to use a for loop and check each individual character. Is there an easier way to do this?
char string[] = "Fishing tourism miami atlanta dallas houston";

I am currently trying to make a simple method for an array that would find the highest value. here is currently what i got, but do not know what to change to make it correct.
double FindMax(double stock[], int size){
int size = stock.length();
int max = stock[0];
for(int i = 1; i < size; i++){
if (stock[i] > max)
{max = stock{i};}
}
return max;

I have everything down except for the highest # and lowest number being displayed.
The arrays are 23, 4, 76, 89, 12, 43, 37, 67, 21, 14.
I have the average which is 38.6 but i stuck getting highest number and lowest.

Here is my code and everything works except i can not get the highest array number to be output. it always says 10.
My instructions are:
(1) Create a 10-integer array called data
(2) Set a pointer ptr to point to array data
(3) Output the elements in array data using pointer ptr
(4) Find the largest element in the array data using pointer ptr
#include <iostream>
#include <cstdlib>
using namespace std;

I am doing a modification to a school project call rainfall statistics. I have that written, but need to sort the array and list rainfall totals from highest to lowest. I thought I knew what I was doing but I am having some difficulty locating all my errors, the error I keep getting now is:

it compiles and runs, it gives me the average and the highest score but says lowest is 0 even though 0 is never entered.
Write a program which uses an array of 5 scores and calculates the average score, the highest score and the lowest score.
#include <iostream>
using namespace std;
int getHighest(int [], int);
int getSmallest(int [], int);
double getAverage(int [], int);
int count;
int numbers;

I am writing a function called swap that sorts the elements of an array in order from highest to lowest values where they descend and ascend. A particular thing about this function is that swap does NOT re-arrange elements in the array so it just uses a second array of indexes for the elements in the original array and then swap sorts the second array based on the values in the original array. A sorted version of the original array can then be produced with these sorted indexes. You can declare and initialize the original array without any user input.
For example, int arr[10] = {1, 5, 22, 14, 6, -5, 7, 9, 12, 15 };
Header of the function swap must be as shown below: void swap(int array[],int swapedIndexes [], int size, char mode) When mode is 'a', the function sorts the array in the ascending order, and when mode is 'd', the function sorts it in the descending order. int swappedIndexes[5];swap(array,swappedInde… 5, 'a');
So far I have this code that randomly generates arrays of 10 elements and I found the max and min, but I am confused on what to do about the swapping part? Also, how to make the numbers ascend or descend in numerical order?? Here is what i have done so far:
#include<ctime>
#include <iostream>
using namespace std;
int min(int [],int);
void max(int [],int , int &);
void main()
{ srand(time(0));
//1-declare

Using the array to accept 10 testscore. Calculate and print the highest, lowest, fifth test score entered and all the test score entered in reverse order.
How i would get it to print the highest,and lowest and in reverse order. I'm confused as to what to do...

Assume you want to use a loop to process an array of characters starting from the beginning of the array. You want the loop to stop when you read the null terminator character from the array. Fill in the loop test condition that will make this work correctly.
index = 0;
ch = array[index];
while ( _____________________________)
{
// process the character
index++;
ch = array[index];
}
