Answer / tata indicom
What if the first element which you are assigning to max and
secondmax is itself the largest number in array.....
In such a case you will not be able to find second largest in
the array.....

System.out.println("max::"+max);
if(max != scndMax)
{
System.out.println("scndMax::"+scndMax); }
else { System.out.println("scndMax does not
exist"); }
}
}
this will give output in all conditions..njoy

Answer / anand
Initializing second_largest to max negative number will ensure for all (+ve and -ve range of values).
int secondLargestNumber(int arr[],int numberOfValues)
{
int largest=arr[0];
int second_largest= -(2^(sizeof(int)*8 -1));
int i;
for(i=1;i<numberOfValues;i++)
{
if(a[i]>largest)
{
secondLargest=largest;
largest=a[i];
}
if(a[i]>secondLargest && a[i]<largest)
secondLargest=a[i];
}
return secondLargest;
}
