Write a program in c language to find first and second largest number from array.

#include <stdio.h>
#include <conio.h>
int main()
{
    int i, a[10], loc1=0, loc2=0, max1=0, max2=0;
    for(i=1; i<=5; i++)
    {
             printf("Enter number: ");
             scanf("%d", &a[i]);
    }
    for(i=1; i<=5; i++)
    {
             if(max1<a[i])
             {
                    max2=max1;
                    max1=a[i];
                    loc2=loc1;
                    loc1=i;
             }
             if(max2<a[i] && a[i]<max1)
             {
                     max2=a[i];
                     loc2=i;
             }
    }
    printf("First largest is %d  at %d and Second largest is %d at %d",max1, loc1, max2, loc2);
    getch();
}
