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);

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 am trying to take a string that is within the main function, and write a void function that gives me the most common alpha character used inside the string. How to mix a string and an array together like that as I am not too familiar with arrays yet.
View 8 Replies View RelatedI'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);

Am I on my right way using if/else?
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.

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 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;

My professor said we only needed 1 for loop as you only need to read the data from one column in each?
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.
So I'm trying to create a function that replaces any instance of a character in a string with another. So first I tried the replace() string member function:
In my implementation file
void NewString::ReplaceChar(const char& target,const char& entry)
{
this->replace(this->begin(),this->end(), target, entry);
};
Main program
#include "NewString.h"
using namespace ...;
int main()
[Code].....
Instead of replacing the the l's with y's it outputted a long string of y's. Also, NewString is derived from the string class (it's for the assignment). the header and whole implementation file, already tested.
I've also tried, instead, to use a for loop in ReplaceChar() but I need to overload the == operator and I don't know how I should exactly:
bool NewString::operator ==(const char& target)const {
if(*this == target)
return true;
[Code]....
I want the == operator to test if the value in the char array is equal to target but I'm not sure how to pass in the position. I'm guessing the this pointer in ReplaceChar() is not the same as the one dereferenced in ==() because target is never replaced by entry in the string.
I can't find the highest digit within c-string. Ithe user was to enter 1234. the highest shall be 4 but can't get that number.
int Hnum(char* str) {
//int size = 0;
int H = 0, remainder, div =0;
int intstr = atoi(str);
[Code] ....
I need to find a string with leading spaces like " target sting" inside another sting.
And I need to find something like "target sting" inside another sting.
I used .IndexOf() but noticed it ignores leading spaces.
So then I went with .Substring() but that doesn't seem like that's the best solution either.
I have a question about this function.
Code:
char a[4] = {"aaa"};
strstr(a, "bb");
When I do this after function copies bb to the array it puts '' ? I mean last for array would be 'b' 'b' 'a' '' or 'b' 'b' '' ''. I am trying to learn the basics of searching a string, finding and changing them with another string.
i just want to check to see if one word (string) or one sentance is equal to any others within an array. My code
so basically i want to check if a is equal to either "sleep", "in", or "bed". Or even if the string within a is equal to "sleep in bed" as one string.
I have used the following but even if i get it correct and it says correct it says incorrect another 2 times because it is saying yeah you have gotten one right out of the possible 3. Even if I type "sleep in bed" it still does it (prints out incorrect another 2 times. Also are there any good books to start off with c++?
string a;
string aa[3] = {"sleep", "in", "bed"};
for(int i = 0; i < 3; i++) {
if(a == aa[i]) {
cout << "CORRECT!" << endl;
} else {
cout << "INCORRECT!" << endl;
}
}
I'm trying to get the int value of each character in a string and then add them all together so I can do a 1's complement of the total value. I'm trying to do simple checkum kinda of thing for verification of data.
For example: string DPacket = "Hello World!";
I would like to have each character added and do the ones complement. Will it be easier to convert first to int and then add or any other easier way? So my result should be the decimal value addition of each character and then do the ones complement to that.
#include <iostream>
#include <string>
#include <iomanip>
using namespace std;
int main()
{
//Program Goal
//Have 3 Strings to represent 3 categories
//Have the user type in their name
//Have the user type in a full sentence how they are feeling
//Program should find the word in the user inputted sentence and display an appropriate response

I want to find that whether the 2d Vector table having duplicate or not. I can see lot of programs for removing duplicates by using unique STL algorithm. Which is the best way to find " is Duplicate or not " for 100,000 Records.
View 1 Replies View RelatedI know how to find the occurrences of a character in a string, but I have a more specific problem.
For example, consider the string:
" C 1.3825 4.0000 12.0000 1.9133 0.1853 0.9000 -1.1359 4.0000 "
I want to extract a vector that contains the positions of every first character for each number.
For the example above, the output should be a vector with elements [6 15 23 33 etc...]. These are the positions of the first character for every number.
I need to be able to do this for any arbitrary string with any arbitrary amount of numbers and characters in it (I also need to account for negative numbers).
i couldnt solve the algorithm exactly. The program asks the user for a string. "Bugun h@v@ cok g'uzel" for example. then the program asks for another string. If that string doesnt exists in the main string program should say there isnt any substring. If it exist then the program should print the remaining part of main string. For example:
Write the first string: Tod@y weather is be'@utiful
write the substring : ug
>>ugun h@v@ cok guzel
write the substring :wldnqwbdbj
>>there isnt any substring
Here where i came so far
#include <stdio.h>
int main()
{
char mainstr[50],substr[50];
[Code]....
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 know how to remove certain characters from a string by using something like this:
Code: string str ("Hello world!");
erase (0, 6);
That's great if I want to do that manually, but say if someone entered a string, how would I automatically remove every other character they entered?
I want to check whether a certain character is in a string or not but my code is not working

#include<stdio.h>

Let's say i have a string "file.txt" and i want to insert "_out" to make it look like "file_out.txt"
I don't know how to do this ....
Copy some characters from char * arg to char * first using a loop with specific conditions.
Code:
char * arg;
// set arg some string...
char first_[25];
char * first;
int length;
length=strlen(arg);
for (n++; arg[n] != '}' || n>=length-1; n++)
strcpy(first,arg[n]); // first += arg[n]; I have strcpy(first,arg[n]); but arg[n] is char and strcpy expects char * ;
how to solve this?
It's been about two years since I last program c, now I need to do it for a basic project. How would I print out one letter in a string?
For example lets say I have a string called str=[Hello]. I want to display the third letter so just the "l". Here's what I have so far:
Code:
#include<stdio.h>
int main() {
char str[50] = "Hello";
printf("The third letter is : %s
",str[3]);
return 0;
}
