To find smallest and largest numbers out of 6 numbers by using not more than 6-8 line

[aimi95]

Hello all, I'm new here. I found these forums to be very useful so I decided to join.
My question is that, my teacher specially gave a task to me. We just started problem solving and C++ coding so I'm not very good at it but I'm good than rest of my class (according to my teacher) and he gives me certain tasks to do. My new task is to find smallest, largest and average of six numbers (we haven't studied arrays yet, so I'm bound not to use it)by usings 6-8 lines of main logic I tried to do it by this way:

 #include<iostream>
using namespace std;
 
void main()
{
int n1,n2,l=0,s=0,i;
 
cout<<"Enter Number: ";
cin>>n1;
 
for(i=2; i<=6; i++)
{
    cout<<"\nEnter next number: ";
    cin>>n2;
 
    if(n2>n1)
    {
        l=n2;
        s=n1;
    }
    else
    {
        l=n1;
        s=n2;
    }
    n1=n2;
}
cout<<"\nLargest number is"<<l<<"\nSmallest number is"<<s;
} 

but it gives me wrong results. It seems like the program is making decisions based on the last two values for variable n2. Is my logic correct? or should I make some changes within the program?
Thanks in advance for your valuable time .

Hello! You could solve this problem like this: use a for statement with i going from 1 to 6. At each iteration, input an integer and add it to a running total (initialized to 0). Also, if i is 1, initialize the largest and smallest variable with the current integer input. If not, check whether the current integer input is smaller than the smallest number so far. Apply the same logic for keeping track of the largest number. At the end of the for statement, find the average by dividing the running total by 6. =)

Without overthinking it, it looks like this won't work without using a third integer as your "random" number. Also, your For loop was a little messy. I've written the following code and I hope it helps you!

 {
int largeNumber;
int smallNumber;
int randomNumber;
int i;
 
cout<<"Enter Number: ";
cin>>randomNumber;
largeNumber = randomNumber;
smallNumber = randomNumber;
 
 for(i=0; i<5; i++)
{
    cout<<"\nEnter next number: ";
    cin>>randomNumber;
 
    if(randomNumber > largeNumber)
    {
        largeNumber = randomNumber;
    }
    else
        if(randomNumber < smallNumber)
    {
        smallNumber = randomNumber;
    }
}
cout<<"\nLargest number is"<<largeNumber<<"\nSmallest number is"<<smallNumber;
std::cin.get();
getchar();
} 

Edit**:
This line of code may not be necessary. I used it in Visual Studio so I could pause the output window:

std::cin.get();
getchar();

Visual Studio will pause the output window automatically if you select "run without debugging" as opposed to "run". No need for code you might have to take out as you move from development to release.

@weaknessforcat s, Thanks! I learn something new every day.
