C Basic Declarations and Expressions: Exercise-132 with Solution

Write a Java program to find heights of the top three building 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;
  printf("Input heights(integer values) of the top eight buildings:\n");
  for(i=0;i<8;i++)
  { scanf("%d",&heights[i]); }
  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;
  }
  printf("\nHeights of the top three building:\n");
  printf("%d\n%d\n%d\n",heights[0],heights[1],heights[2]);

  return 0;
}

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

C Programming: Tips of the Day

Static variable inside of a function in C

The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().

The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.

The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
