#include%26lt;iostream%26gt;
using namespace std;

int numCount, total;
double average;
cout %26lt;%26lt; "How many numbers do you want to average? ";
cin %26gt;%26gt; numCount;
for (int count = 0; count %26lt; numCount; count++)
{
int num;
cout %26lt;%26lt; "Enter a number: ";
cin %26gt;%26gt; num;
total += num;
}
average = total / numCount;
cout %26lt;%26lt; "The average is " %26lt;%26lt; average %26lt;%26lt; endl;
return 0;
}
What is wrong with this C++ program?
dude int total get initialized to garbage value..
so use
int numCount,total=0;
this should giv u the correct answer
#include%26lt;iostream%26gt;
using namespace std;
int main()
{
int numCount, total=0;
double average;
cout %26lt;%26lt; "How many numbers do you want to average? ";
cin %26gt;%26gt; numCount;
for (int count = 0; count %26lt; numCount; count++)
{
int num;
cout %26lt;%26lt; "Enter a number: ";
cin %26gt;%26gt; num;
total += num;
}
average = total / numCount;
cout %26lt;%26lt; "The average is " %26lt;%26lt; average %26lt;%26lt; endl;
return 0;
}
Reply:total/numCount is integer devided by integer wil result in fraction part truncated. Also all vaiables need to be initialized to 0.
Two Solutions
1. Use datatype casting: i.e., You can replace
average = total/numCount ;
with
average=(double)total / (double) numcount;
2. Initialize numcount and Total as double/float datatype
instead of integer.
Reply:It looks ok to me. The only thing I would suggest is initializing your variables to something so you know you don't have junk in them. So set numCount and total to 0 at the top and also set average to 0.0 and don't forget to set num = 0 in your for loop as well. I'm not sure exactly what the problem is or if there is one since you didn't mention a specific error.
Reply:Try placing the "int num;" outside of the for.
for total, make it "total = total + num;"
Remember to close everything, even "for" with a ";"
If this doesn't fix it, can you say what exactly the problem is when it runs?
It's been a long time since C++, sorry if I'm wrong.
