You need to read a number before you check its value.

Also you need to initialize sum with 0.

more explain plz

float num; leaves num uninitialized. Reading from it is actually not allowed and does chaotic stuff.

You need to put a value into in first.

Divide by the number of numbers you added. You'll need to add a separate variable for the counter that counts 1 up every time a variable is added and divide the sum by the counter at the end.

int main()
{
float num=1 ,sum=0,count=0,avg;
while(num!=0)
{
    cout<<"enter num\n";
    cin>>num;
    sum+=num;
    count++;
}
avg=sum/count;

cout<<"sum="<<sum<<"\n";
cout<<"avg="<<avg;

like that ?

[distant osprey]

Looks right

You don't need avg, you can do cout<<"avg="<< sum/count; directly.

Your code doesn't handle incorrect input, if someone presses just enter without entering a number or entering "Lol" your program will endlessly print "enter num". This might not matter if it's for an assignment that tells you not to care about that.
