    A Sorting is the best way to find the largest and second largest no in an array of any size
    ex: quick sort
    after performing the sorting
    directly printing the 1st and 2nd element in an array gives the answer....:)

    CpjJwWHV   Of course NOT sorting can be done in logn in best case,but this question can be solved in 2n only.

    CpjJwWHV   void max(int *a)
    {
    int first_max, second_max;
    if(a[0]>a[1])
    {
    first_max=a[0];
    second_max=a[1];
    }
    else
    {
    first_max=a[1];
    second_max=a[0];
    }
    for(i=2;i<n;i++)
    {
    if(a[i]>second_max)
    {
    second_max=a[i];
    if(second_max>first_max)
    swap(second_max,first_max);
    }
    }
    printf("first_max=%d,second_max=%d",first_max,second_max);
    }

    A #include<stdio.h>
    #include<conio.h>
    int main()
    {
    int max1=0,max2=0,arr[100],n,i=0;
    printf("\n enter the number of elements: \n" );
    scanf("%d",

    CpjJwWHV   very bad approach... wenever changing the largest variable, add dis statement after dat
    slargest= largest; dis will automatically make slargest to second largest element.
