cout << the sum is <

cout<< the average is << average;

cout << the largest is <
cout << the smallest is << Snumber;

return 0;






and this is how my output supposed to look.


How many number do you wish to enter 6
Enter a number: 4
Enter a number: 11
Enter a number: 2
Enter a number: 15
Enter a number: 7
Enter a number: 12

The sum is 51
The average is 8.50
The largest is 15
The smallest is 2

The guy above me is exactly right, you should have set the variable called sum to 0 first, otherwise the program will use whatever junk value is already stored within it.
When you are finished using a particular bit of memory and delete the contents, you aren"t actually getting rid of the content, the memory is just flagged as available for writing to and the contents remain until they are written over.
The memory allocated to sum will have been used for something else previously, this could be anything at all: a variable in another one of your programs or something completely unrelated in some other software It"s always a good idea to initialise your variables on declaration if possible.

Another thing I"ve just noticed is the classic =/== error in your if statements. = operator is assignment, which will evaluate to true, you need == to test for equality. It"s nothing to be ashamed of as every programmer has and still does make this mistake from time to time, no exceptions.

Hope this helps.

I am a beginner myself but I think you need to set sum to 0 to start.

int sum = 0

1. on the first line i replaced the int with double, because the result of an integer division is different from the result of a double division.
2. all variables became inititalized to zero with exception of Lnumber and Snumber
3. Lnumber is initialized to an arbitrary value defined in limits.h LONG_MIN
4. Snumber is initialized to an arbitrary value defined in limits.h LONG_MAX.
5. the average calculated by your formula is different from the average output in your sample screen.
6. In case the first number entered is smaller than LONG_MIN or larger than LONG_MAX this code won"t work.
7. In front of the cout section (where you output your results) I closed the for loop.

#include
#include
#include
using namespace std;

int main()

double Hmany = 0.0,
Enumber = 0.0,
sum = 0.0,
Lnumber=LONG_MIN,
Snumber = LONG_MAX;
double average = 0.0;

cout << How many numbers do you wish to enter ;
cin >> Hmany;

for (int i=0; i cout << Enter a Number: ;
cin >> Enumber;
sum = sum + Enumber;

if (Lnumber Lnumber = Enumber;

if (Snumber>Enumber)
Snumber = Enumber;


cout << the sum is < average = sum/Enumber;
cout<< the average is << average << endl;
cout << the largest is < cout << the smallest is << Snumber << endl;
system(Pause);
return 0;

A couple minor things first:
- Initialize your variables to 0 first
- NULL is for pointers, check if the number is 0
- In the if( ) statements, you want == not =, assignments are always true
- you never figure out the average, but you print it anyway

but your biggest logic problem is probably this:

if (Lnumber=NULL)
Lnumber=Enumber;
else;

I don"t think you want the semicolon after the else, it makes for a null else clause

You have a number of problems here:
- not initializing variables
- missing on your "for" statement
- using = instead of == for equality check ( = is assignment )
- using the last number entered for your avg caculation, instead of Hmany
- using integer arithmetic for your avg calculation

Your code should look something like this:

#iinclude
#include
#include

using namespace std;

int main(int argc, char *argv[])
int Hmany, Enumber,sum = 0,
Lnumber = INT_MIN, Snumber = INT_MAX;
double average;

cout << How many numbers do you wish to enter ;
cin >> Hmany;

for (int i = 0; i < Hmany; i++)
cout << Enter a Number : ;
cin >> Enumber;
sum += Enumber;
Lnumber = max(Enumber, Lnumber);
Snumber = min(Enumber, Snumber);


cout << endl << the sum is << sum << endl;
average = static_cast(sum) / Hmany;
cout << the average is << average << endl;
cout << the largest is << Lnumber << endl;
cout << the smallest is << Snumber << endl;

return 0;


#if 0

Sample run:

How many numbers do you wish to enter 6
Enter a Number : 4
Enter a Number : 11
Enter a Number : 2
Enter a Number : 15
Enter a Number : 7
Enter a Number : 12

the sum is 51
the average is 8.5
the largest is 15
the smallest is 2

#endif
