Question

Write a C program to do the following: 1. Write a C function named find that receives a one-dimensional array of type character named arr and its size of type integer. After that, the function must select a random index from the array. The function must find if the character stored in the randomly selected index comes before all the characters to its left alphabetically. Finally, the function prints to the screen the element if the element meets the condition and "element does not meet the conditions" otherwise. Example arr = [b, c, a, d, e) if the randomly selected index was 2, the function must print element meets the condition to the screen because the character a comes before all the elements to its left (b, c) alphabetically. 2. Write a main function where you define an array of characters named myArr of size 10. Then fill the array from the user and call the function named find you defined in part 1 of this question.

Answer 1

// C code

#include<stdio.h>
#include <stdlib.h>
#include <time.h>
//function prototype
void find(char arr[], int size);
//Function definition
void find(char arr[], int size)
{
   int lower = 0;
   int upper = size - 1;
   //select index randomly
   int index = (rand() % (upper - lower + 1)) + lower;
  
   bool condition = false;
   for (int i = index-1; i >= 0; i--)
   {
       //Compare characteres
       // to check condition
       if ( arr[index]<arr[i])
       {
           condition = true;
          
       }
       else
       {
           condition = false;
       }
   }
   printf("index = %d is selected\n", index);
   if (!condition)
   {
       printf("element does not meet the conditions.\n");
   }
   else
   {
       printf("element meets the condition.\n");
   }
}

//main() function
int main()
{
   //to seed the random number with respect
   //to time
   srand(time(0));
   const int size = 10;
   //Create array of size 10
   char myArr[size];
   printf("Enter characters: \n");
   for (int i = 0; i < size; i++)
   {
       printf("Enter character %d: ", (i + 1));
       scanf_s(" %c", &myArr[i]);
      
   }
   //Print the array
   printf("myArr = [ ");
   for (size_t i = 0; i < size; i++)
   {
       printf("%c, ", myArr[i]);
   }
   printf(" ]\n");
   //Call function
   find(myArr, size);
   return 0;
}

//Output

Enter characters: Enter character 1: g Enter character 2: h Enter character 3: j Enter character 4: d Enter character 5: j Enter character 6: d Enter character 7: r Enter character 8: t Enter character 9: y Enter character 10: u myArr = [ g, h, j, d, j, d, r, t, y, u, ] index = 4 is selected element does not meet the conditions.
