Need help finding error in persons code

Question

#include <iostream>
using namespace std;
in main()
{
int numCount, total;
double average;

cout << "How many numbers do you want to average? " ;
cin >> numCount;

for (int count =0; count < numcount; count++)
{
int num;
cout << "Enter a number: " ;
cin >> num;
total += num;
count ++;
}
average = total / numCount;
cout << "The average is" << average << endl;

system ("pause");
return 0;
}

Answer 1

the / operator's behavior depends on the operands' type. In your case you have int / int and it will return the result of floor division ( 7/2 = 3 ). To return the real average either cast or declare the total as double.

Answer 2

I don't know C++
I can demonstrate in C

#include<stdio.h>

main()
{
int n , i ;
double avg , sum = 0 ,o ;
puts("Enter number of observation");
scanf("%d",&n);
puts("Enter your Observations");
for(i=1;i<n;i++)
{ scanf("%f",&o);
sum += o;
}
avg = sum/n;
printf("The average is %f ",avg);
}

Answer 3

#include <iostream>
#include <stdlib.h>
using namespace std;
int main()
{
int numCount, total;
double average;

total=0;
cout << "How many numbers do you want to average? " ;
cin >> numCount;

for (int count =0; count < numCount; count++)
{
int num;
cout << "Enter a number: " ;
cin >> num;
total += num;
}
average = total / numCount;
cout << "The average is : " << average << endl;

system ("pause");
return 0;
}
it is a correct code

Answer 4

I spotted a 1, maybe 2 if we count the typo,errors there.
Instead of asking around, why not learn how to use a debugger?

Answer 5

besides that is it fine ?

Answer 6

#include <iostream>
using namespace std;
in main()
{
int numCount, total, num;
double average;

cout << "How many numbers do you want to average? " ;
cin >> numCount;

for (int count =0; count < numcount; count++){

cout << "Enter a number: " ;
cin >> num;
total += num;
// delete this line count ++;
}
//average = total / numCount;
average = double(total) / double(numCount);
cout << "The average is" << average << endl;

system ("pause");
return 0;
}
