Program to find largest and smallest among 5 numbers without using array

Question

Yesterday I went for an interview where I have been asked to create a program to find largest and smallest among 5 numbers without using array.

I know how to create

Answer 1

int findMin(int t1, int t2, int t3, int t4, int t5)
{
    int min1, min2, min3;

    min1 = std::min(t1, t2);
    min2 = std::min(t3, t4);
    min3 = std::min(min1, min2);
    return std::min(min3, t5);
}

int findMax(int t1, int t2, int t3, int t4, int t5)
{
    int max1, max2, max3;

    max1 = std::max(t1, t2);
    max2 = std::max(t3, t4);
    max3 = std::max(max1, max2);
    return std::max(max3, t5);
}

These functions are very messy but easy to follow and thus easy to remember and it only uses the simple min and max methods which work best for 2 values.

Answer 2

void main()
{
int a,b,c,d,e,max;
    max=a;
    if(b/max)
        max=b;
    if(c/max)
        max=c;
    if(d/max)
        max=d;
    if(e/max)
        max=e;
    cout<<"Maximum is"<<max;
}

Answer 3

Heres what I did, without using an array. This was a method to return the highest number of 5 scores.

double findHighest(double score1, double score2, double score3, double score4, double score5)
 {
   double highest = score1;
   if (score2 > score1 && score2 > score3 && score2 > score4 && score2 > score5)
      highest = score2;
   if(score3 > score1 && score3 > score2 && score3 > score4 && score3 > score5)
      highest = score3;
   if(score4 > score1 && score4 > score2 && score4 > score3 && score4 > score5)
      highest = score4;
   if (score5 > score1 && score5 > score2 && score5 > score3 && score5 > score4)
      highest = score5;
   return highest;
 }

An array is going to be far more efficient, but I had to do it for homework without using an array.
