Find heights of top three tallest buildings

Write a C program to find the heights of the top three buildings in descending order from eight given buildings.

Input:
0 <= height of building (integer) <= 10,000

Sample Solution:

C Code:

#include<stdio.h>

int main(){

  int heights[10], i, j, h, max_heights;

  // Prompt the user to input heights of the top eight buildings
  printf("Input heights (integer values) of the top eight buildings:\n");

  // Read the heights into the array
  for(i = 0; i < 8; i++){
    scanf("%d", &heights[i]);
  }

  // Sorting the heights in descending order
  for(i = 0; i < 8; i++){
    max_heights = i;
    for(j = i; j < 8; j++){
      if(heights[j] > heights[max_heights]){
        max_heights = j;
      }
    }
    h = heights[max_heights];
    heights[max_heights] = heights[i];
    heights[i] = h;
  }

  // Printing the heights of the top three buildings
  printf("\nHeights of the top three buildings:\n");
  printf("%d\n%d\n%d\n", heights[0], heights[1], heights[2]);

  return 0; // End of program
}

Sample Output:

Input heights(integer values) of the top eight buildings:
25
15
45
22
35
18
95
65

Heights of the top three building:
95
65
45
