Question

C Programming. Do not use a function in the solution.

Assignment 6 This assignment focuses on using arrays.

Instructions Create a program called arrays.c that does the following:

1. Prompt the user for a string (<= 100 characters). (using the attached file: AS06Data.txt)

AS06Data.txt file contains the text "

Instructions: When your executing program displays "Enter string 1:" starting with T, select the line of text below, copy with ctrl-c, then  type ctrl-v



THIS IS a test of string 0123456789  +~_!)@()#($*%&^ stuff"

2. Display the frequency table showing the total number of characters entered by the user, the count for each character entered by the user, and the percentage of the total count that is attributed to each character. Display in the same order as the sample output below

The absolute frequency of a character is the number of times the character appears. For example, in the string "aaab" the absolute frequency of 'a' is 3, and the absolute frequency of 'b' is 1.

The relative frequency of a character is the absolute frequency divided by the total number of characters. For example, in the string "aaab" the relative frequency of 'a' is 3/4 = 0.75, and the relative frequency of 'b' is 1/4 = 0.25. Relative frequency * 100 will give you the result in percentage

Please look at my code and in case of indentation issues check the screenshots.

---------------arrays.c----------------

#include <stdio.h>

int main()
{
   char inputString[1000];                       //create char array to store input string
   printf("Enter string 1: ");
  
   fgets(inputString, 1000, stdin);           //read string
   inputString[strlen(inputString)-1] = '\0';   //set newline into null character

   // Declaration and initialization of an array to store the char frequency
   int frequency[256] = {0};                   //we will use ASCII number of a character as an input

   int i;

           percent = (float) frequency[i]/ (float) total * 100;       //computer percent
           printf("\"%c\" \t %d \t %.2f \n", i, frequency[i], percent);
       }

   return 0;
