C Exercises: Find heights of the top three building in descending order from eight given buildings
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

For more Practice: Solve these Related Problems:
- Write a C program to sort an array of building heights in descending order and print the top three values.
- Write a C program to use selection sort to determine the three maximum values from an array of eight building heights.
- Write a C program to scan building heights into an array, then iterate to extract and display the top three heights without sorting the entire array.
- Write a C program to use a temporary array to store and then display the three tallest building heights from user input.
