LARGE ARRAY

• Problem Description

  
  Read in "n" integer numbers into an array and find the average of two largest given numbers without sorting the array. The program should output the given the average

• CODING ARENA

• #include <stdio.h>

  #include <limits.h>

  
  

  int main()

  {

    int a[10], n;

    int l1,l2,i;

    float c;

    scanf("%d",&n);

    for(i=0;i<n;i++)

      scanf("%d",&a[i]);

    l1=l2= INT_MIN;

    for(i=0;i<n;i++)

    {

      if(a[i]>l1)

      {

        l2=l1;

        l1=a[i];

    }

        else if(a[i]>l2 && a[i]<l1)

        l2=a[i];

    }

    

    printf("First Largest=%d",l1);

    printf("\nSecond Largest=%d",l2);

    c=(float)(l1+l2)/2;

    printf("\nAverage=%.1f",c);

    return 0;

  }
