Letter Frequency Write a function that will take a string and return a count of each letter in the string. For example, "my dog

ate my homework" contains 3 m's, 3 o's, 2 e's, 2 y's and one each of d, g, a, t, h, w, r and k. 2 Your function should take a single string argument and return a dynamically allocated array of 26 integers representing the count of each of the letters a . . z respectively. Your function should be case insensitive, i.e., count 'A' and 'a' as the occurrence of the letter a. [Hint: use the letter to integer conversion functions.] Do not count non-letter characters (i.e., spaces, punctuation, digits, etc.) Write a program that will solicit a string from the user using getline, call your letter frequency function and print out the frequency of each letter in the string. Do not list letters that do not occur at least once. Example: Enter a string: my dog at my homework Letter frequency a 1 d 1 e 1 g 1 h 1 k 1 m 3 o 3 r 1 t 1 w 1 y 2

Answer:

Check the explanation

Explanation:

Code to copy:

// ConsoleApplication7.cpp : Defines the entry point for the console application.

//

#include "stdafx.h"

#include <iostream>

#include <cstring>

#include <string>

using namespace std;

int * letterFrequency(char s[]);

int main()

{

  int *freq_letters;

  char *s = new char[100];

  freq_letters = new int[26];

  //To read the input string in order to find the frequency of each letter

  cout << "Enter a string: ";

  cin.getline(s, ' ');

  //call the function to find the occurrence of each alphabet

  freq_letters = letterFrequency(s);

  //Display the count

  cout << "Letter Frequency " << endl;

  for (int i = 0; i < 26; i++)

  {

      //Constriant to check if the letter appeared at least once in the string and so printing the frequency of its occurence

      if (freq_letters[i] != 0)

      cout << " " << static_cast<char>(i + 'a') << " " << freq_letters[i] << endl;

  }

  system("pause");

  return 0;

}

//Define the function to find occurrence of each letter in the input string

int * letterFrequency(char s[])

{

  int *occurrence_array;

//to store the output of occurrences for each alphabet

  occurrence_array = new int[26];

// to store the count of occurrence for each letter temporarily

  int letter_count;

  // for loop to check the occurrence for all 26 alphabets

 

  for (int i = 0; i < 26; i++)

  {

      letter_count = 0;

      for (int j = 0; j < strlen(s); j++)

      {

          /*comparing the ascii values of each alphabet with every character from the string by converting it to lower case i.e. case insensitive*/

          if (int('a') + i == int(tolower(s[j])))

              letter_count++;

      }

      occurrence_array[i] = letter_count;//To store the count calculated for each alphabet

  }

  return occurrence_array;

}

The following below code screenshot and output shows that when the string is entered, the output will shows each lettercount irrespective of whether the letter is in capitals or small and does not count non-letter characters (i.e spaces, punctuations etc.)

Write a program that reads a list of integers, and outputs those integers in reverse. The input begins with an integer indicatin
lyudmila [28]

Answer:

Following is the program in C language :

#include <stdio.h> // header file

#define n 5 //  macro

int main() main function

{

   int a[n],k1; // variable and array declaration

   printf("Enter the element:\n");

   for(k1=0;k1<n;++k1) //iterating the loop

   {

       scanf("%d",&a[k1]);//Read the values by user

   }

   printf("Output in Reverse Order:\n");

   for(k1=n-1;k1>=0;--k1)//iterating the loop

   {

   printf(" %d ",a[k1]); //Display the values

   }

   return 0;

}

Output:

Enter the element:

4

3

45

67

89

Output in Reverse Order: 89 67 45 3 4

Explanation:

Following is the description of the program

  • Define a macro "n" with value 5 after the header file.
  • Declared an array "a" and defined the size of that array by macro i.e "n".
  • Read the value by the user by using scanf statement in the array "a"
  • Finally In the last for loop display the values of array "a" by space.

* Create a list of places and situations in which we use a computer
Vinvika [58]

Answer:

Place:

Coffee shop. Railway Reservation System, Airport Reservation System, Machine learning and a long list follow.

Situation:

We find that there is a similar type of calculation and in bulk. Thus we can create a piece of software, and run that with the help of a computer to solve our problem of tackling the massive number of clients.

Description:

The situation demands a similar sort of calculation, and we can hence make a program or most favorably a software that can do all these calculations for us. A perfect example is a coffee shop, which has 100 to 1000 customers drinking coffee each second. And you can understand how badly they need a computer and software. This cannot be done manually.
