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

• Test Case 1

  
  Input (stdin)

  4
  
  80 23 79 58
  
  

  Expected Output

  First Largest=80
  
  Second Largest=79
  
  Average=79.5

• Test Case 2

  
  Input (stdin)

  5
  
  180 23 179 58 43
  
  

  Expected Output

  First Largest=180
  
  Second Largest=179
  
  Average=179.5

• Program

• #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;
